Laravel 8 CRUD Tutorial Step By Step

Laravel 8 crud example tutorial. In this post, i will show you from scratch on how to build/make simple crud application in laravel 8 with validation.

The crud means create, read, update and delete records from database.

In this example post, i will create blog post crud (create , read, update and delete) app in laravel with validation.

This tutorial will completely guide you from scratch to create crud app in laravel 8 for beginners.

Laravel 8 CRUD – Simple CRUD Example Tutorial

• Step 1 – Install Laravel 8 Application

• Step 2 – Configuring Database using Env File

• Step 3 – Create Post Model & Migration

• Step 4 – Create Routes

• Step 5 – Creating Resource Controller

• Step 6 – Create Blade Views File

• Step 7 – Start Development Server

• Step 8 – Run Laravel 8 CRUD App On Browser

Step 1 – Install Laravel 8 Application

In step 1, open your terminal and navigate to your local web server directory using the following command:

//for windows user
cd xampp/htdocs

//for ubuntu user
cd var/www/html

Then install laravel 8 latest application using the following command:

composer create-project --prefer-dist laravel/laravel Laravel8Crud

Step 2 – Configuring Database using Env File

In step 2, open your downloaded laravel 8 app into any text editor. Then find .env file and configure database detail like

DB_CONNECTION=mysql
DB_HOST=127.0.0.1
DB_PORT=3306
DB_DATABASE=db name
DB_USERNAME=db user name
DB_PASSWORD=db password

Step 3 – Create Post Model & Migration

In step 3, open command prompt and navigate to your project by using the following command:

cd / Laravel8Crud

Then create model and migration file by using the following command:

php artisan make:model Post -m

The above command will create two files into your laravel 8 form validation application, which is located inside the following locations:

• Laravel8Crud/app/Models/Post.php

• Laravel8Crud/database/migrations/create_posts_table.php

Now, find Post.php model file inside Laravel8Crud/app/Models directory. And open it then add the fillable property code into Post.php file, like following:

<?php

namespace App\Models;

use Illuminate\Database\Eloquent\Factories\HasFactory;
use Illuminate\Database\Eloquent\Model;

class Post extends Model
{
    use HasFactory;

    protected $fillable = [
        'title', 'description'
    ];
}

Then, find create_posts_table.php file inside Laravel8Crud/database/migrations/ directory. Then open this file and add the following code into function up() on this file:

 public function up()
    {
        Schema::create('posts', function (Blueprint $table) {
            $table->id();
            $table->string('title');
            $table->text('description');
            $table->timestamps();
        });
    }

Now, open again your terminal and type the following command on cmd to create tables into your selected database:

php artisan migrate

Step 4 – Create Routes

In step 4, open your web.php file, which is located inside routes directory. Then add the following routes into web.php file:

use App\Http\Controllers\PostCRUDController;

Route::resource('posts', PostCRUDController::class);

Step 5 – Creating Resource Controller

In step 5, create resource controller by using the following command:

php artisan make:controller PostCRUDController --resource

The above command will create PostCRUDController.php file, which is located inside LaravelForm/app/Http/Controllers/ directory.

The following laravel validation rules will validate form data before store into database in laravel:

$request->validate([
            'title' => 'required',
            'description' => 'required',
        ]);

So open PostCRUDController.php file and add the following code into it:

<?php
  
namespace App\Http\Controllers;
   
use App\Models\Post;
use Illuminate\Http\Request;
  
class PostCRUDController extends Controller
{
    /**
     * Display a listing of the resource.
     *
     * @return \Illuminate\Http\Response
     */
    public function index()
    {
        $data['posts'] = Post::orderBy('id','desc')->paginate(5);
    
        return view('posts.index', $data);
    }
     
    /**
     * Show the form for creating a new resource.
     *
     * @return \Illuminate\Http\Response
     */
    public function create()
    {
        return view('posts.create');
    }
    
    /**
     * Store a newly created resource in storage.
     *
     * @param  \Illuminate\Http\Request  $request
     * @return \Illuminate\Http\Response
     */
    public function store(Request $request)
    {
        $request->validate([
            'title' => 'required',
            'description' => 'required',
        ]);
    
        Post::create($request->all());
     
        return redirect()->route('posts.index')
                        ->with('success','Post has been created successfully.');
    }
     
    /**
     * Display the specified resource.
     *
     * @param  \App\post  $post
     * @return \Illuminate\Http\Response
     */
    public function show(Post $post)
    {
        return view('posts.show',compact('post'));
    } 
     
    /**
     * Show the form for editing the specified resource.
     *
     * @param  \App\post  $post
     * @return \Illuminate\Http\Response
     */
    public function edit(Post $post)
    {
        return view('posts.edit',compact('post'));
    }
    
    /**
     * Update the specified resource in storage.
     *
     * @param  \Illuminate\Http\Request  $request
     * @param  \App\post  $post
     * @return \Illuminate\Http\Response
     */
    public function update(Request $request, Post $post)
    {
        $request->validate([
            'title' => 'required',
            'description' => 'required',
        ]);
    
        $post->update($request->all());
    
        return redirect()->route('posts.index')
                        ->with('success','Post updated successfully');
    }
    
    /**
     * Remove the specified resource from storage.
     *
     * @param  \App\Post  $post
     * @return \Illuminate\Http\Response
     */
    public function destroy(Post $post)
    {
        $post->delete();
    
        return redirect()->route('posts.index')
                        ->with('success','Post has been deleted successfully');
    }
}

Step 6 – Create Blade Views File

In step 6, create one directory name posts inside resource/views directory. Then create new 3 blade views file that named create.blade.php, edit.blade.php and index.blade.php inside resources/views/posts directory.

The following code display error message in laravel add and edit blog post forms. So do not forget to add the following code laravel add edit blog posts forms:

  @if ($errors->any())
        <div class="alert alert-danger">
            <strong>Whoops!</strong> There were some problems with your input.<br><br>
            <ul>
                @foreach ($errors->all() as $error)
                    <li>{{ $error }}</li>
                @endforeach
            </ul>
        </div>
    @endif

Don’t worry i have already added the validation error message display code along with each form fields.

So, you can add the following php and html form code into create.blade.php, edit.blade.php and index.blade.php:

posts/create.blade.php

Step 7 – Start Development Server

Finally, open your command prompt again and run the following command to start development server for your simple laravel 8 crud app:

php artisan serve

Step 8 – Run Laravel 8 CRUD App On Browser

In step 8, open your browser and fire the following url into your browser:

http://127.0.0.1:8000/posts

When you fire the above given url on browser, simple laravel 8 crud app will look like in the following images:
