When you start learning any programming, you start building basic application functionalities. CRUD is the basic things you build in any application.

In this tutorial, I have created simple CRUD application for beginners from the scratch. So if you are new to Laravel, this tutorial will help you to understand the basic MVC structure of Laravel.

We are going to build blog application which includes creating, editing showing and deleting post. We will go through step by step from the starting. You can also build the Laravel CRUD application using this tutorial.

The tutorial will follows below steps:

• Step 1: Create new Laravel application
• Step 2: Configure database environment
• Step 3: Create and run database migration
• Step 4: Create Post model
• Step 5: Create application routes
• Step 6: Create PostController controller
• Step 7: Create blade view for payment button
• Step 8: Test CRUD application

Prerequisite: We assume that you have already installed LAMP server into your Ubuntu system. We also assument that you have installed Composer which is used to create Laravel application and managing PHP packages.

So, let's start from creating fresh Laravel application.

Step 1: Create new Laravel application

We are going to start tutorial from creating new Laravel 8 application. We will use Composer application command to create latest Laravel application. To start with tutorial, open the Terminal or CMD and run the below Composer command to create Laravel application.

composer create-project laravel/laravel blog --prefer-dist

After the project is created, change Terminal directory to project root.

cd blog

Step 2: Configure database environment

In the second step, we will setup database and configure into our Laravel application. Laravel database configuration are stored at .env file of root directory. Open the .env file and change the database with your MySQL database and credentials.

DB_CONNECTION=mysql
DB_HOST=127.0.0.1
DB_PORT=3306
DB_DATABASE=blog
DB_USERNAME=root
DB_PASSWORD=root

Step 3: Create and run database migration

After we have setup database, we need to create tables into database. For that first create migration class for database table. Run the following command into Terminal to create migration file.

php artisan make:migration create_posts_table

This will create migration file at database/migrations directory. Open that file and add new fields into up() method.

<?php

use Illuminate\Database\Migrations\Migration;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Support\Facades\Schema;

class CreatePostsTable extends Migration
{
    /**
     * Run the migrations.
     *
     * @return void
     */
    public function up()
    {
        Schema::create('posts', function (Blueprint $table) {
            $table->id();
            $table->string('title');
            $table->text('body');
            $table->timestamps();
        });
    }

    /**
     * Reverse the migrations.
     *
     * @return void
     */
    public function down()
    {
        Schema::dropIfExists('posts');
    }
}

Now run the migrate command into database.

php artisan migrate

This will create posts table into database with other few default tables.

Step 4: Create Post model

Model classes are used to communicate with database and stored at app/Models directory. Generate new Post model using following Artisan command:

php artisan make:model Post

Step 5: Create application routes

Now we need to create application routes. We are building CRUD application, so you can define resource route. Open application route file routes/web.php and add following new resource route.

<?php

use Illuminate\Support\Facades\Route;
use App\Http\Controllers\PostController;

Route::resource('post', PostController::class);

Step 6: Create PostController controller

We have defined routes which redirects to PostController controller class. So, create resource controller class using following Artisan command.

php artisan make:controller PostController --resource

This will create new resource controller class at app/Http/Controllers/PostController.php file. The resource class includes following methods with routes.

Verb URI Action Route Name

GET /post index post.index

GET /post/create create post.create

POST /post store post.store

GET /post/{id} show post.

GET /post/{id}/edit edit post.edit

PUT/PATCH /post/{id} update post.update

DELETE /post/{id} destroy post.destroy

Now add the below codes into each method.

<?php

namespace App\Http\Controllers;

use App\Models\Post;
use Illuminate\Http\Request;

class PostController extends Controller
{
    /**
     * Display a listing of the resource.
     *
     * @return \Illuminate\Http\Response
     */
    public function index()
    {
        $posts = Post::orderBy('id', 'desc')
            ->get();

        return view('post.index', compact('posts'));
    }

    /**
     * Show the form for creating a new resource.
     *
     * @return \Illuminate\Http\Response
     */
    public function create()
    {
        return view('post.create');
    }

    /**
     * Store a newly created resource in storage.
     *
     * @param  \Illuminate\Http\Request  $request
     * @return \Illuminate\Http\Response
     */
    public function store(Request $request)
    {
        $input = $request->validate([
            'title' => 'required',
            'body' => 'required',
        ]);

        Post::create($input);

        return redirect()->route('post.index');
    }

    /**
     * Display the specified resource.
     *
     * @param  int  $id
     * @return \Illuminate\Http\Response
     */
    public function show($id)
    {
        $post = Post::find($id);

        return view('post.show', compact('post'));
    }

    /**
     * Show the form for editing the specified resource.
     *
     * @param  int  $id
     * @return \Illuminate\Http\Response
     */
    public function edit($id)
    {
        $post = Post::find($id);

        return view('post.edit', compact('post'));
    }

    /**
     * Update the specified resource in storage.
     *
     * @param  \Illuminate\Http\Request  $request
     * @param  int  $id
     * @return \Illuminate\Http\Response
     */
    public function update(Request $request, $id)
    {
        $input = $request->validate([
            'title' => 'required',
            'body' => 'required',
        ]);

        Post::where('id', $id)
            ->update($input);

        return redirect()->route('post.index');
    }

    /**
     * Remove the specified resource from storage.
     *
     * @param  int  $id
     * @return \Illuminate\Http\Response
     */
    public function destroy($id)
    {
        Post::find($id)
            ->delete();

        return redirect()->route('post.index');
    }
}

Your Post model file is at app/Models/Post.php. Add $fillable attribute array with posts table fields name in the model.

protected $fillable = [
    'title',
    'body',
];

Step 7: Create blade view

Now we need to create blade view files to show and handle the data. Laravel view files are stored at /resource/views/ directory. We need following blade files.

File Used for

layouts/app.blade.php main layout file

post/index.blade.php show list for posts

post/show.blade.php show specific post

post/create.blade.php create post

post/edit.blade.php edit post

layouts/app.blade.php

<html>
<head>
	<meta charset="utf-8">
	<title>Post</title>
	<link href="https://cdn.jsdelivr.net/npm/[email protected]/dist/css/bootstrap.min.css" rel="stylesheet">

	<div class="container mt-5">

					</td>
				</tr>
			@empty
			    <tr>
			    	<td colspan="4" class="text-center">No posts found.</td>
			    </tr>
			@endforelse
		</tbody>
	</table>

Step 8: Test CRUD application

SO far we need to completed the CRUD application. Now we need to test the application. First, start the Laravel server using below command.

php artisan serve

And in your browser window, run the url http://localhost:8000/post and try to add, edit and remove post.

Conclusion

Finally, we have completed the Laravel 8 simple CRUD operation tutorial. So this way, you can implement the CRUD operation in your learning curves. I hope this tutorial is helpful for those who are new and want to start from the scratch into Laravel.
