CRUD Operations In Laravel 8

This tutorial is created to illustrate the basic CRUD (Create , Read, Update, Delete) operation using SQL with Laravel 8. Laravel is one of the fastest-growing frameworks for PHP. Laravel 8 continues the improvements made in the previous stable release. Refer release notes to see the changes made in Laravel 8.

In this tutorial, Youโ€™ll learn to create the basic CRUD operations in Laravel. Follow the step-by-step guide to implement CRUD in Laravel 8.

What is CRUD?

When we are creating any dynamic web applications, it deals with some database operations such as Create, Read, Update, and Delete which are the four basic functions that we implement with the model. Hence, Software Engineers or Computer scientists often refer to these functions with the acronym CRUD .

  1. Install Laravel

First, let install Laravel using the following command (Make sure you have installed composer in your PC). Click on Install Composer If you havenโ€™t installed Composer on your PC.

composer create-project --prefer-dist laravel/laravel stock_management
  1. Configure the Database

You need to create the database at MYSQL and then we need to connect that database to the Laravel project (You can also use phpmyadmin to create the database). Open the .env file inside Laravel project and add the database credentials as below.

.env

DB_CONNECTION=mysql DB_HOST=127.0.0.1 DB_PORT=3306 DB_DATABASE='Your DB Name' DB_USERNAME='Your DB UserName' DB_PASSWORD='Your DB Password'
Code language: JavaScript (javascript)
  1. Create the Stock Model and Migration

Next we are going to create the model using the following artisan command which will create the Model and the corresponding migration file.

php artisan make:model Stock -m
Code language: CSS (css)

Open app/Models/Stock.php file and define the modal values in the $fillable prop.

app\Models\Stock.php

<?php namespace App\Models; use Illuminate\Database\Eloquent\Factories\HasFactory; use Illuminate\Database\Eloquent\Model; class Stock extends Model { use HasFactory; public $fillable = [ 'product_name', 'product_desc', 'product_qty' ]; }
Code language: HTML, XML (xml)

The migration will be created under โ€œdatabase/migrationsโ€œ. Edit the file with the code below to create Stock Table.

database/migrations/timestamp_create_stocks_table.php

<?php use Illuminate\Database\Migrations\Migration; use Illuminate\Database\Schema\Blueprint; use Illuminate\Support\Facades\Schema; class CreateStocksTable extends Migration { /** * Run the migrations. * * @return void */ public function up() { Schema::create('stocks', function (Blueprint $table) { $table->increments('id'); $table->string('product_name'); $table->text('product_desc'); $table->integer('product_qty'); $table->timestamps(); }); } /** * Reverse the migrations. * * @return void */ public function down() { Schema::dropIfExists('stocks'); } }
Code language: HTML, XML (xml)

Type the following command to run the migration.

php artisan migrate
  1. Create Seeder

Next we are going to add some dummy data to the stock table using laravel Seeder using the following artisan command.

php artisan make:seeder StockTableSeeder
Code language: CSS (css)

All seeders generated will be placed in the database/seeders directory.

database\seeders\StockTableSeeder.php

<?php namespace Database\Seeders; use App\Models\Stock; use Illuminate\Database\Seeder; class StockTableSeeder extends Seeder { /** * Run the database seeds. * * @return void */ public function run() { Stock::create([ 'product_name' => 'Twinty Pencil', 'product_desc' => 'HB 5 Drawing Pencil', 'product_qty' => 100, ]); } }
Code language: HTML, XML (xml)

So, we have added the columns product_nameproduct_descproduct_qty values that will be stored in the database. Run the following command to execute StockTableSeeder :

php artisan db:seed --class=StockTableSeeder
Code language: JavaScript (javascript)
  1. Create Route and Resource Controller

Now, Itโ€™s time to create the logic for CRUD operations. We will use the Resource Controller to define the operations under the pre-defined methods within the Resource Controller. Run the following Artisan command to create the Stock resource controller.

php artisan make:controller StockController --resource
Code language: CSS (css)

In this step, Go to routes->web.php file, add the following line of code to direct the routes to Stock Controller.

<?php use App\Http\Controllers\StockController; use Illuminate\Support\Facades\Route; // Redirects to the Stock Resource Controller Route::get('/', function () { return redirect('/stocks'); }); Route::resource('stocks', StockController::class);
Code language: HTML, XML (xml)

Add the following lines of codes in StockController to manipulate the basic CRUD operations.

app\Http\Controllers\StockController.php

<?php namespace App\Http\Controllers; use App\Models\Stock; use Illuminate\Http\Request; class StockController extends Controller { public function index() { $stocks = Stock::latest()->paginate(5); return view('stocks.index',compact('stocks'))->with('i', (request()->input('page', 1) - 1) * 5); } public function create() { return view('stocks.create'); } public function store(Request $request) { $request->validate([ 'product_name' => 'required', 'product_desc' => 'required', 'product_qty' => 'required', ]); Stock::create($request->all()); return redirect()->route('stocks.index')->with('success','Created Successfully.'); } public function show(Stock $stock) { return view('stocks.show',compact('stock')); } public function edit(Stock $stock) { return view('stocks.edit',compact('stock')); } public function update(Request $request, Stock $stock) { $request->validate([ 'product_name' => 'required', 'product_desc' => 'required', 'product_qty' => 'required', ]); $stock->update($request->all()); return redirect()->route('stocks.index')->with('success','Updated Successfully.'); } public function destroy(Stock $stock) { $stock->delete(); return redirect()->route('stocks.index')->with('success','Student deleted successfully.'); } }
Code language: HTML, XML (xml)
  1. Create the Views

Finally, create a folder Inside the resources\views directory as stocks within that folder, create the following five files.

  1. layout.blade.php
  2. index.blade.php
  3. create.blade.php
  4. edit.blade.php
  5. show.blade.php

layout.blade.php

Installing PHP on Windows

What is PHP?

PHP is known to be one of the most commonly used server-side programming language on the web. It provides an easy to master with a simple learning curve. It has close ties with the MySQL database, and various libraries to cut your development time.

Two Ways to install PHP locally

There are several ways that we could install PHP locally. Here i have added two of the most common ways to install PHP as shown below.

  1. Installing a Web Server (XAMPP, WAMP etc)
  2. Implementing via PHP Installer
Installing a Web Server

There are many all-in-one packages are available for Windows and other OSโ€™s which comes with Apache, PHP, MySQL and other applications as a single file installer, e.g. XAMPP, WampServer, MAMP etc. There is no any issue in going with these packages, however manually installing Apache and PHP will help you to have more control and access to its configuration options.

XAMPP :
https://www.apachefriends.org/index.html

WampServer :
https://www.wampserver.com/en/

MAMP :
https://www.mamp.info/en/windows/

Implementing via PHP Installer

It provides several benefits for backing up, reinstalling, or moving the web server can be executed easily in a short amount of time and it provides more control over PHP and Apache configuration. In the Manual Installation, you need to configure several steps in order to install PHP successfully.

Step 1 : Download the PHP package & Extract THE FILES

Get the PHP version 8.0 or later (x64 Thread Safe) package zip file via navigating under the windows downloads URL mentioned in the link below.

https://www.php.net/downloads.php.

After, downloading the zip successfully to your PC, create a folder as “PHP” in any drive and extract the PHP package files into it.

STEP 2 : CONFIGURE PHP

Initially php.ini file doesn’t exist inside the php package files. so copy {drive_name}:\php\php.ini-development and rename it as {drive_name}:\php\php.ini whereas the default configuration provides a development setup.

To uncomment a setting inside the php.ini file you need to remove a leading semicolon (;). Uncomment the following lines to enable the required extensions whereas the following extensions are mostly required by many PHP frameworks and for other operations.

extension=curl extension=gd extension=mbstring extension=pdo_mysql
Step 3 : Add PHP to The environment variable

To access PHP globally at your PC add the PHP package path by following the steps below.

  • Step 1: Click the Windows Start button and type โ€œenvironmentโ€.
  • Step 2: Click Edit the system environment variables. Select the Advanced tab, and click the Environment Variables button.
  • Step 3: Scroll down the System variables list and click Path followed by the Edit button.
  • Step 4 : Click New and add {drive_name}:\php:

NOTE: You are not required to reboot the PC, but you may need to close and restart any cmd terminals if you have opened before.

STEP 4 : Test a PHP file

Create a new file named index.php and add the following lines of codes and save it.

<?php phpinfo(); ?>
Code language: HTML, XML (xml)

Run the PHP file by entering the following command in CMD where you have created the index.php file.

php index.php
Code language: CSS (css)

Programming is one of the most important skill to be mastered in todayโ€™s world. If you are new to the field of software engineering, the very first question comes to your mind is โ€œWhatโ€™s the best Programming Language to Master ?โ€ thatโ€™s an important question to decide your programming career. There are many popular programming languages to learn in 2020. Letโ€™s find out the best 5 programming languages to master.

Disclaimer :

The information provided in this article is my own personal opinion and it’s no mean of degrading any programming languages available today. Feel free to share your opinion in the comment section.

#1 Python

Python

Python is a high-level, general-purpose programming language which has been emerging in 2020 as one of the most frequently used language in the area of data science, Artificial Intelligence and Machine Learning. Created by Guido van Rossum. Python has been a growing programming language ever since the release. Python is largely used in web applications, desktop apps, network servers, machine learning and more. Python is considered to be the fastest language and it’s very easy to learn and it has fewer syntactical constructions than other languages.

Learn Python via Learn to CODE

Data scientists and people from Computer Science have involved in scripting based open-source language. to use it for their ML algorithms, techniques, and Jobs in Data Science.

Python is comparatively easy to learn and code with minimal syntax. It provides a huge array of in-built libraries and frameworks for Data Science which consist of Bokeh, Pandas, Numpy, Scipy, Matplotlib, StatsModel with extension framework for Deep learning include

  • Theano.
  • Lasagne.
  • Blocks.
  • TensorFlow.
  • Keras.
  • MXNet.
  • PyTorch.

Here is an example for a simple Python โ€œHello World!โ€ program:

print ("Hello World!")
Code language: PHP (php)
Learning CurveEasy to Learn
Job opportunityHigher

#2 JS

JS

JavaScript is used as the โ€œfrontendโ€ programming language in web apps. It’s most commonly used as a client-side scripting language. If you have mastered any other programming languages before, then learning JavaScript will be much easier for you.

Why JavaScript is Used?

JavaScript is commonly known for its usability for the front-end of the web. Although JS is used for many other areas. Along with the front-end of the web, It’s been widely used for the following areas.

JS powered Mobile Applications

Most of the Mobile Applications are developed using Native Languages which are provided by their OS (Operating System). Although Cross-Platform Development is widely used to get rid of the pain of coding more than once. The mobile JS frameworks like React Native and PhoneGap are created to facilitate Android and iOS development with one single code base. This helps the developers to use JS to build mobile applications easily.

Web Applications

JS is not only limited to front-end development for the interactive web. But the development of new frameworks and libraries are allowing users to develop a lot of back-end programs with JS. which includes interactive web apps and server apps. JS is widely used in previous years and it continues to grow because of its flexibility and speed. These are few of the JavaScript frameworks popularly used by developers today.

Games

Most of the developers are very familiar with JS than other languages. Due to this, It’s possible to develop games via JS. When it comes to the modern browsers They have the capability of rendering WebGL, they can render complex 3D and 2D graphics without the need for third-party applications. These are some of the JS engines to build games.

Here is an example of a simple JavaScript โ€œHello World!โ€ program:

<script> document.getElementById("demo").innerHTML = "Hello JavaScript!"; </script>
Code language: HTML, XML (xml)
Learning CurveIf you are fluent in any other languages. then it’s easy to learn.
Job opportunityHigh

#3 Java

Java is a general-purpose, high-level programming language. It’s intended to let application developers โ€œwrite once, run anywhereโ€ (WORA), meaning that compiled Java code can run on all platforms. Java was originally developed by James Gosling at Sun Microsystems (which has since been acquired by Oracle Corporation) and released in 1995.

Java is also widely used in Mobile Application Development, Web Application Development and Creating Desktop Applications.

  1. Desktop Base Applications :Desktop Applications can be created using libraries like Java Swing or JavaFX. They provide components to create text boxes, graphics and buttons for the GUI.
  2. Web Base Applications : Java provides support for web application through Servlets and JSPs.
  3. Mobile Base Applications : Native Android Applications are written in Java. Furthermore, Android Studio provides development tools for developing in Java.

Here is an example of a simple Java โ€œHello World!โ€ program:

class Hello { public static void main(String args[]){ System.out.println("Hello World"); } }
Code language: JavaScript (javascript)
Learning CurveIf you are good at OOP. then, It would be easy to learn.
Job opportunityHigher

#4 Kotlin

Kotlin

Kotlin is founded by JetBrains and it has been open source since 2012. It’s an Open Source, General Purpose statically typed pragmatic programming language for the Android and Java Virtual Machine. You can find the Open Source Kotlin Project on GitHub. Kotlin is becoming one of the trending languages in 2020.

Google Announced the support for Kotlin in Android Studio IDE three years back at I/O 2017. Which led the long-time preferred language Java for Android to switch into Kotlin.

The Syntax of Kotlin is minimal, clean and modern. It’s very easy to learn Kotlin because of it’s minimal and easy to understand nature. It’s similar to Apple’s Swift Language.

Here is an example of a simple Kotlin โ€œHello World!โ€ program:

println("Hello World!")
Code language: JavaScript (javascript)

The support of Kotlin Multiplatform aims to extend the compatibility to other platforms and it incorporates the developers to reuse the code and their expertise by reducing the tasks to implement twice or thrice.

With the swift growth of its presence among the developers, Kotlin is already in a phase of adapting to Data Science. Some of the following tools and libraries are now supporting data science as listed below.

  • Apache Spark & Apache Zeppelin: Kotlin is used in Spark Java API from both Jupyter and Zeppelin.
  • Jupyter: Now you can use Kotlin kernel for Jupyter notebooks by accessing third-party data science frameworks written in Java and Kotlin.

Learn the basics of Kotlin with Learn to CODE

Learning CurveRelatively easy to learn when comparing to other languages. The syntax is similar to JAVA.

#5 Swift

Swift is a high-level, Open Source, General-Purpose, Compiled programming language created for iOS Development, OS X, watchOS by Apple. Swift language is based on Objective-C, which was used for NeXTSTEP development. It’s an alternative to the Objective-C language which was the most popular language for building apps for Apple Platform.

Swift is easy to use and with syntactic simplicity to match Python. Which can be used to build apps much faster with less learning curve.

Here is an example of a simple Swift โ€œHello World!โ€ program:

import Swift print("Hello, World!")
Code language: JavaScript (javascript)
Learning CurveSoft Learning Curve.

PHP Array Functions and their usage with examples

This tutorial is created to give an abstract idea about commonly used PHP array function with examples. Through this tutorial you’ll be able to know, how to use array functions to make code more short and simple.

Note:

I’ll be only covering some of the basicย array functions, Which were frequently used by PHP developers. You can refer all the array functions from the officialย PHP Documentation. Feel free to share your opinion in the comment section.

Creating an Array in PHP

PHP array is created using an array() function. There are basically three types of arrays in PHP

  1. Indexed arrays – An array with a numeric index.
  2. Associative arrays – An array with named keys.
  3. Multidimensional arrays – An array containing one or more arrays.

To create an indexed array, add array values inside the parentheses, separated by commas.

$randomNames = array("Peace","Love","BH","Bishrul","Haq");
Code language: PHP (php)

OR

$randomNames = array(); $randomNames[0] = "Peace"; $randomNames[1] = "Love"; $randomNames[2] = "BH"; $randomNames[3] = "Bishrul"; $randomNames[4] = "Haq";
Code language: PHP (php)

Let’s look into some of the PHP functions in detail.

  1. List()

List function is used to Assign variables as if they were an array. It helps to insert without assigning values to each array index.

$names = array("Dev","BH","Peace"); // without list function() $one = $names[0]; $two = $names[1]; $three = $names[2]; // with list function() list($one,$two,$three) = $names; echo 'one : '. $one.' two : '. $two.' three : '. $three;
Code language: PHP (php)

Output

Array ( [0] => BH [1] => is [2] => Carm )
Code language: PHP (php)
  1. preg_slit() or explode()

These two functions are used to split a string by a given string. Which helps to skip string, if you don’t need them to be shown.

$words = 'BH|is|Carm'; $array = explode('|', $words); // exploded words are displayed in the array print_r($array);
Code language: PHP (php)

Output

one : Dev two : BH three : Peace
  1. extract()

extract() function is used to export an associative array to variables. For every array element, a variable will be created with the name of a key and value as a value of the element.

$details = [ 'name' => 'bishrul', 'age' => '24', 'color' => 'fair', ]; extract($details); echo("$name $age $color");
Code language: PHP (php)

Output

bishrul 24 fair
  1. compact()

It’s the exact opposite of explode() function, Which convert the given variables into an associative array.

$name = 'bishrul'; $age = '24'; $color = 'fair'; $array = compact('name', 'age', 'color'); print_r($array);
Code language: PHP (php)

Output

Array ( [name] => bishrul [age] => 24 [color] => fair )
Code language: PHP (php)
  1. array_combine()

Which creates an array by using one array for array keys and another for its array values.

$keys = ['name', 'age', 'color']; $values = ['bishrul', '24', 'fair']; $details = array_combine($keys, $values); print_r($details);
Code language: PHP (php)

Output

Array ( [name] => bishrul [age] => 24 [color] => fair )
Code language: PHP (php)
  1. array_merge()

To merge two or more arrays into one array array_merge() is used. values of arrays will be merged together, and values with the same keys will be overwritten with the last array.

$array1 = ['one' => '1', 'two' => '2', 'three' => '3']; $array2 = ['one' => '11', 'four' => '4', 'three' => '33']; $merge = array_merge($array1, $array2); print_r($merge);
Code language: PHP (php)

Output

Array ( [one] => 11 [two] => 2 [three] => 33 [four] => 4 )
Code language: PHP (php)
  1. array_sum() & array_product()

array_sum() is used to get the sum of given array values and array_product() to multiply the given array values.

PHP Program to remove empty or specific array elements.

This tutorial is created to remove specific or empty (NULL) array elements from the array.

  1. array_filter() to Remove Empty Elements

array_filter() function removes false values when declared using a callback function, however, If the callback function returns true, the current value from input is returned into the result array.

  1. $array (mandatory): This is where the input array is given.
  2. $callback_function (optional): The user-defined function is given . If the function is not given then all entries of the array equal to FALSE and will be removed.
  3. $flag (optional): The arguments passed to the callback function is defined.
    • ARRAY_FILTER_USE_KEY โ€“ Only key argument is passed to the callback function, instead of the value of the array.
    • ARRAY_FILTER_USE_BOTH โ€“ Both value and key as arguments to callback instead of the value.

Syntax :

array array_filter($array, $callback_function, $flag)
Code language: PHP (php)

Below is a program showing how to return filtered array elements using array_filter() function.

<?php // Declaring the array $array = array("bishrul", 27, '', null, "developer", 45,"for", 1994, false,); // Function to remove empty elements $filtered_array = array_filter($array); // Display the array var_dump($filtered_array);
Code language: HTML, XML (xml)

Output :

array(6) { [0]=> string(7) "bishrul" [1]=> int(27) [4]=> string(9) "developer" [5]=> int(45) [6]=> string(3) "for" [7]=> int(1994) }
Code language: PHP (php)
  1. unset() Function to Remove Empty Elements.

The Another way is to remove empty elements from array is using empty() function along with the unset() function. The empty() function is used to check whether the element is empty is not.

<?php // Declaring the array $array = array("bishrul", 27, '', null, "developer", 45,"for", 1994, false,); // Loop to find empty elements foreach($array as $key => $value) if(empty($value)){ unset($array[$key]); } // Displaying the array foreach($array as $key => $value) echo ($array[$key] . " , "); ?>
Code language: HTML, XML (xml)

Output :

bishrul , 27 , developer , 45 , for , 1994 ,

Removing a specific value using unset() function in PHP.

<?php // Declaring the array $array = array("bishrul", 27, '', null, "developer", 45,"for", 1994, false,); // Loop to find empty elements foreach($array as $key => $value) if($value == "bishrul"){ unset($array[$key]); } // Displaying the array foreach($array as $key => $value) echo ($array[$key] . " , "); ?>
Code language: HTML, XML (xml)

Output :

27 , , , developer , 45 , for , 1994 , ,

Connecting Multiple Databases in Laravel 5.8

This tutorial is created to implement multiple database connections using mysql. Letโ€™s see how to configure multiple database connections in Laravel 5.8.

# Laravel 5.8

Laravel 5.8 continues the improvements made in the previous release (version 5.7). Referย release notesย to see the changes made in Laravel 5.8.

  1. Install Laravel 5.8

First, let’s install Laravel 5.8 using the following command (Make sure to have composer installed in your PC) to Install Composer.

composer create-project --prefer-dist laravel/laravel multiDatabase
  1. Configure Database Details

You need to configure the databases at MYSQL and then we need to connect that database to the Laravel project (You can also use phpmyadmin to create the database). Open the .env file inside Laravel project and add the database credentials as below.

.env

DB_CONNECTION=mysql DB_HOST='Your DB Host' DB_PORT='Your DB Port' DB_DATABASE='Your DB Name' DB_USERNAME='Your DB UserName' DB_PASSWORD='Your DB Password' DB_CONNECTION_2=mysql DB_HOST_2='Your DB Host' DB_PORT_2='Your DB Port' DB_DATABASE_2='Your DB Name' DB_USERNAME_2='Your DB UserName' DB_PASSWORD_2='Your DB Password'
Code language: JavaScript (javascript)

In this step, Update โ€œconfig/database.phpโ€ with following code to create database connections.

config/database.php

'default' => 'mysql', 'connections' => [ 'mysql' => [ 'driver' => env('DB_CONNECTION'), 'host' => env('DB_HOST'), 'port' => env('DB_PORT'), 'database' => env('DB_DATABASE'), 'username' => env('DB_USERNAME'), 'password' => env('DB_PASSWORD'), .... ], 'mysql2' => [ 'driver' => env('DB_CONNECTION_2'), 'host' => env('DB_HOST_2'), 'port' => env('DB_PORT_2'), 'database' => env('DB_DATABASE_2'), 'username' => env('DB_USERNAME_2'), 'password' => env('DB_PASSWORD_2'), .... ] ]
Code language: PHP (php)
  1. Create the migration file.

Go to the terminal and type the following php artisan command to generate the model and migration file.

php artisan make:migration create_multi_data_table
Code language: CSS (css)

The migration will be created under “database/migrations”. Edit the file with the code below to Create Multi Data Table.

create_multi_data_table.php

<?php use Illuminate\Support\Facades\Schema; use Illuminate\Database\Schema\Blueprint; use Illuminate\Database\Migrations\Migration; class CreateMultiDataTable extends Migration { /** * Run the migrations. * * @return void */ public function up() { Schema::connection('mysql2')->create('multiData', function (Blueprint $table) { $table->increments('id'); $table->string('name'); $table->text('detail'); $table->timestamps(); }); } /** * Reverse the migrations. * * @return void */ public function down() { Schema::connection('mysql2')->dropIfExists('multiData'); } }
Code language: HTML, XML (xml)

Type the following command to run the migration.

php artisan migrate --database=mysql2
  1. Create Controller and model

If you encounter any errors, Clear the cache by running the following command.

php artisan config:cache
Code language: CSS (css)

Create the multiData model using the following command.

php artisan make:model multiData
Code language: CSS (css)

The model wil be generated in “app/multiData.php” Now, we will write the schema inside multiData.php file. Specify the โ€œ$connectionโ€ variable as shown below.

multiData.php

<?php namespace App; use Illuminate\Database\Eloquent\Model; class multiData extends Model { protected $connection = 'mysql2'; }
Code language: HTML, XML (xml)

Create the MultiDataController by typing the following command.

php artisan make:controller MultiDataController
Code language: CSS (css)

app/Http/Controllers/MultiDataController.php

<?php namespace App\Http\Controllers; use App\Student; use Illuminate\Http\Request; class MultiDataController extends Controller { public function yourMethod() { $multiData = new multiData; $multiData->setConnection('mysql2'); $multi = $multiData->find(1); return $multi; } }
Code language: HTML, XML (xml)

You can also define custom connection with query builder as shown below

DB::connection('mysql2')->select(...)->(...);
Code language: PHP (php)

Simple PHP MySQL CRUD Application

PHP is widely used by many developers today and it’s one of the easiest language to learn. This tutorial will help you to learn the basic CRUD (Create, Read, Update, Delete) operations in PHP using MYSQL.

PHP CRUD
  1. Create the DB(Database) file

Create the DB as ‘php_crud’ and run the following SQL query to create table users inside the MySQL ‘php_crud’ database.

Creating the DB
Creating the DB

SQL query to create a table named users

Table in PHP CRUD
Creating the Table
CREATE TABLE users ( id INT NOT NULL PRIMARY KEY AUTO_INCREMENT, name VARCHAR(100) NOT NULL, address VARCHAR(255) NOT NULL, age INT(10) NOT NULL );
Code language: PHP (php)

Now, It’s time to create the DB config.php file as shown below

config.php

<?php define('DB_SERVER', 'localhost'); define('DB_USERNAME', ''); define('DB_PASSWORD', ''); define('DB_NAME', 'php_crud'); $link = new mysqli(DB_SERVER, DB_USERNAME, DB_PASSWORD, DB_NAME); if ($link->connect_errno) { printf("Connect failed: %s\n", $link->connect_error); exit(); }
Code language: HTML, XML (xml)
  1. Creating the Pages

Create the landing page for the CRUD application that contains a table to show the records from the users table.

index.php

<?php require_once "config.php"; $sql = "SELECT * FROM users"; $result = $link->query($sql); ?> <!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>PHP CRUD : bishrulhaq.com</title> <link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0/css/bootstrap.min.css" integrity="sha384-Gn5384xqQ1aoWXA+058RXPxPg6fy4IWvTNh0E263XmFcJlSAwiGgFAW/dAiS6JXm" crossorigin="anonymous"> <style> .btn{ margin-left: 10px; } </style> </head> <body> <div class="wrapper"> <div class="container"> <div class="row"> <div class="col-md-12"> <div class="card" style="margin-top: 20px;margin-bottom: 20px;"> <div class="card-body"> <h2 class="pull-left">User Details <a href="create.php" class="btn btn-success pull-right">Add New User</a></h2> <h6>Find more interesting tutorials at <a href="https://bishrulhaq.com/">bishrulhaq.com</a></h6> </div> </div> <?php if ($result->num_rows > 0) { echo "<table class='table table-bordered table-striped'>"; echo "<thead>"; echo "<tr>"; echo "<th>#</th>"; echo "<th>Name</th>"; echo "<th>Address</th>"; echo "<th>Age</th>"; echo "<th>Action</th>"; echo "</tr>"; echo "</thead>"; echo "<tbody>"; while ($row = $result->fetch_assoc()) { echo "<tr>"; echo "<td>" . $row['id'] . "</td>"; echo "<td>" . $row['name'] . "</td>"; echo "<td>" . $row['address'] . "</td>"; echo "<td>" . $row['age'] . "</td>"; echo "<td>"; echo "<a href='read.php?id=" . $row['id'] . "' class='btn btn-primary'>Read</a>"; echo "<a href='update.php?id=" . $row['id'] . "' class='btn btn-info'>Update</a>"; echo "<a href='delete.php?id=" . $row['id'] . "' class='btn btn-danger'>Delete</a>"; echo "</td>"; echo "</tr>"; } echo "</tbody>"; echo "</table>"; // Free result set $result->free(); } else { echo "<p class='lead'><em>No records were found.</em></p>"; } $link->close(); ?> </div> </div> </div> </div> </body> </html>
Code language: HTML, XML (xml)

In this step, Let’s create the “create.php” and add the following code inside it.

create.php

<?php require_once "config.php"; if ($_SERVER["REQUEST_METHOD"] == "POST") { if (isset($_POST['name']) && isset($_POST['address']) && isset($_POST['age'])) { $sql = "INSERT INTO users (name, address, age) VALUES (?,?,?)"; if ($stmt = $link->prepare($sql)) { $stmt->bind_param("ssi", $_POST['name'], $_POST['address'], $_POST['age']); if ($stmt->execute()) { header("location: index.php"); exit(); } else { echo "Error! Please try again later."; } $stmt->close(); } } $link->close(); } ?> <!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>Create User : bishrulhaq.com</title> <link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0/css/bootstrap.min.css" integrity="sha384-Gn5384xqQ1aoWXA+058RXPxPg6fy4IWvTNh0E263XmFcJlSAwiGgFAW/dAiS6JXm" crossorigin="anonymous"> </head> <body> <div class="wrapper"> <div class="container"> <div class="row"> <div class="col-md-12"> <div class="page-header"> <h2>Create Users</h2> </div> <p>Fill this form to add users to the database.</p> <form action="<?php echo $_SERVER["PHP_SELF"] ?>" method="post"> <div class="form-group"> <label>Name</label> <input type="text" name="name" class="form-control" required> </div> <div class="form-group"> <label>Address</label> <textarea name="address" class="form-control" required></textarea> </div> <div class="form-group"> <label>Age</label> <input type="number" name="age" class="form-control" required> </div> <input type="submit" class="btn btn-primary" value="Submit"> <a href="index.php" class="btn btn-default">Cancel</a> </form> </div> </div> </div> </div> </body> </html>
Code language: HTML, XML (xml)

Create “delete.php” and add the following code inside it. Which will help to delete a particular user by passing the ID.

delete.php

<?php if (isset($_GET["id"]) && !empty($_GET["id"])) { require_once "config.php"; $sql = "DELETE FROM users WHERE id = ?"; if ($stmt = $link->prepare($sql)) { $stmt->bind_param("i", $_GET["id"]); if ($stmt->execute()) { header("location: index.php"); exit(); } else { echo "Error! Please try again later."; } } $stmt->close(); $link->close(); } else { echo "Error! Please try again later."; } ?>
Code language: HTML, XML (xml)

Now, Let’s Create the “read.php” and add the following code inside it.

read.php

<?php require_once "config.php"; if (isset($_GET["id"]) && !empty(trim($_GET["id"]))) { $sql = "SELECT * FROM users WHERE id = ?"; if ($stmt = $link->prepare($sql)) { $stmt->bind_param("i", $_GET["id"]); if ($stmt->execute()) { $result = $stmt->get_result(); if ($result->num_rows == 1) { $row = $result->fetch_array(MYSQLI_ASSOC); $name = $row["name"]; $address = $row["address"]; $age = $row["age"]; } else { echo "Error! Please try again later."; exit(); } } else { echo "Error! Please try again later."; exit(); } } $stmt->close(); $link->close(); } else { echo "Error! Please try again later."; exit(); } ?> <!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>View User : bishrulhaq.com</title> <link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0/css/bootstrap.min.css" integrity="sha384-Gn5384xqQ1aoWXA+058RXPxPg6fy4IWvTNh0E263XmFcJlSAwiGgFAW/dAiS6JXm" crossorigin="anonymous"> <style> label{ font-weight: bold; } </style> </head> <body> <div class="wrapper"> <div class="container"> <div class="row"> <div class="col-md-12"> <div class="card" style="margin-top: 20px;"> <div class="card-body"> <div class="page-header"> <h1>View User</h1> </div> <div class="form-group"> <label >Name</label> <p class="form-control-static"><?php echo $name; ?></p> </div> <div class="form-group"> <label>Address</label> <p class="form-control-static"><?php echo $address; ?></p> </div> <div class="form-group"> <label>Age</label> <p class="form-control-static"><?php echo $age; ?></p> </div> <p><a href="index.php" class="btn btn-primary">Back</a></p> </div> </div> </div> </div> </div> </div> </body> </html>
Code language: HTML, XML (xml)

Create “update.php” and add the following code inside it. Which will help to update the particular user data

update.php

<?php require_once "config.php"; if (isset($_GET['id'])) { $sql = "SELECT * FROM users WHERE id = ?"; if ($stmt = $link->prepare($sql)) { $stmt->bind_param("i", $_GET["id"]); if ($stmt->execute()) { $result = $stmt->get_result(); if ($result->num_rows == 1) { $row = $result->fetch_array(MYSQLI_ASSOC); $param_name = $row["name"]; $param_address = $row["address"]; $param_age = $row["age"]; } else { echo "Error!

Integrating Google ReCaptcha in Laravel 5.8

reCAPTCHA is a free service from Google. It’s a CAPTCHA-like system designed to recognize that the user is human and, at the same time, assist in the digitization of books. It helps to protects your website from spam and abuse.

Note :

If you’re running the Laravel Project at your Local Server. It’s also acceptable for testing Google reCAPTCHA.

In this tutorial, You’ll learn to integrate Google reCAPTCHA in your Laravel Project. Follow the step by step guide to create the application.

Google Recaptcha
Google Recaptcha
  1. Create reCAPTCHA for your Domain

First, You need to create reCAPTCHA for your domain by logging into Google reCAPTCHA Admin Console.

  1. Set the Keys in .env file

After creating the account, Obtain the Key and Secret. Add them to the .env file as shown below,

.env

RECAPTCHA_KEY='your recaptcha key' RECAPTCHA_SECRET='your recaptcha secret'
Code language: JavaScript (javascript)

You can name the key and secret as you like. I have named them as RECAPTCHA_KEY, RECAPTCHA_SECRET .It is required later in the validation form.

  1. Create the Form Request Validaiton

Create the Custom Validation Rules using form request validation in by typing the following command,

php artisan make:request ReCaptchaFormRequest
Code language: CSS (css)

The generated class will be stored in in the app/Http/Requests file directory. Open ReCaptchaFormRequest.php from the directory and add the validation rules inside the rules method

<?php namespace App\Http\Requests; use Illuminate\Foundation\Http\FormRequest; class ReCaptchaFormRequest extends FormRequest { public function authorize() { return true; } public function rules() { return [ 'g-recaptcha-response'=>'required|recaptcha' ]; } }
Code language: HTML, XML (xml)
  1. Create the Custom Validation with Guzzle

If you donโ€™t have Guzzle, Install it by typing the command below at your terminal

composer require guzzlehttp/guzzle
Code language: JavaScript (javascript)

After installing Guzzle, Create a directory as Validation, Inside the Validation folder, Create a PHP file as ReCaptcha.php and add the code below,

app/Validation/ReCaptcha.php

<?php namespace App\Validation; use GuzzleHttp\Client; class ReCaptcha { public function validate($attribute, $value, $parameters, $validator) { $client = new Client(); $response = $client->post( 'https://www.google.com/recaptcha/api/siteverify', ['form_params' => [ 'secret' => env('RECAPTCHA_SECRET'), 'response' => $value ] ] ); $body = json_decode((string)$response->getBody()); return $body->success; } }
Code language: HTML, XML (xml)

The next step is to register Validation in AppServiceProvider’s Boot method.

public function boot() { Validator::extend('recaptcha','App\\Validation\\ReCaptcha@validate'); }
Code language: CSS (css)
  1. Create the Captcha Controller

Type the following command at your terminal to create CaptchaController.php file in controllers

php artisan make:controller CaptchaController
Code language: CSS (css)

Create two methods as index and captcha in CaptchaController.

app/Http/Controllers/CaptchaController.php

<?php namespace App\Http\Controllers; use App\Http\Requests\ReCaptchaFormRequest; use Illuminate\Http\Request; class CaptchaController extends Controller { public function index() { return view('index'); } public function captcha(ReCaptchaFormRequest $reCaptchaFormRequest) { return "Done!"; } }
Code language: HTML, XML (xml)
  1. Create the Routes

In this step, Go to ‘routes->web.php’ file and add the following code.

Route::get('/','CaptchaController@index'); Route::post('/','CaptchaController@captcha');
Code language: PHP (php)
  1. Create the index.php View File

The final step is to create the index.php file in views directory

resources/views/index.blade.php

<!DOCTYPE html> <html> <head> <title>Laravel 5.8 GOOGLE RECAPTCHA - bishrulhaq.com</title> <link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0/css/bootstrap.min.css" integrity="sha384-Gn5384xqQ1aoWXA+058RXPxPg6fy4IWvTNh0E263XmFcJlSAwiGgFAW/dAiS6JXm" crossorigin="anonymous"> <script src='https://www.google.com/recaptcha/api.js'></script> </head> <body> <div class="container"> <div class="row" style="margin-top: 20px;"> <div class="col-12 "> @if (count($errors) > 0) <div class="alert alert-danger"> <ul> @foreach ($errors->all() as $error) <li>{{ $error }}</li> @endforeach </ul> </div> @endif </div> <div class="col-12 "> <div class="card"> <div class="card-body mx-auto"> <h3 class="text-center" style="font-weight: bold;padding-bottom: 10px;">GOOGLE ReCAPTCHA</h3> <form class="form-horizontal" action="" method="post"> {!! csrf_field() !!} <div class="form-group"> <div class="col-md-12"> <div class="g-recaptcha " data-sitekey="{{env('RECAPTCHA_KEY')}}"></div> </div> </div> <div class="form-group"> <button type="submit" name="submit" class="btn btn-success">Submit</button> </div> </form> </div> </div> </div> </div> </div> </body> </html>
