Laravel 8 - CRUD application tutorial with Example

 

In this article, i will share with you how to make a simple CRUD operation application in laravel 8 with example. as you know laravel 8 already release with the many new features and functionality. this tutorial is for beginners. so, if any start learning laravel then it will be help of them. in this article, i will generate a very simple CRUD application from the start.

Step - 1 : Install Laravel 8

In the very first step, we need to create laravel 8 application in your local system using the following composer command in your terminal.

composer create-project --prefer-dist laravel/laravel laravel8crudapplication

Step - 2 : Database Configuration

now, just open your laravel applications .env file and make the following database related changes in it.

DB_CONNECTION=mysql
DB_HOST=127.0.0.1
DB_PORT=3306
DB_DATABASE=laravelcrud // your database name
DB_USERNAME=root // your database user name
DB_PASSWORD=root // your database password

Step - 3 : Create Migration

Now, need to create migration using the following artisan command in your project root directory.

php artisan make:migration create_post_tbl --create=posts

after running this command you see one migration file in the "database/migrations" folder. open it and make the following changes in it.

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

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

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

then run the following command for run migration

php artisan migrate

Step - 4 : Add Resource Route

Here, we need to create a resource route for our posts CRUS example. so, open your "routes/web.php" file and add the post resource route.

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

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

Step - 5 : Add Controller and Model

In this step, we will create our "PostController" and "Post" model using the following artisan command in terminal.

php artisan make:controller PostController --resource --model=Post

After, run the above artisan command then "app/Http/Controllers/PostController.php". file and "app/Models/Post.php" file created in laravel 8 application. 

In this controller will create seven methods by default as the below methods:

• 1)index()
• 2)create()
• 3)store()
• 4)show()
• 5)edit()
• 6)update()
• 7)destroy()

Now, open the "PostController.php" file and just copy past the following code into it.

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()
    {
        $data = Post::latest()->paginate(5);
    
        return view('posts.index',compact('data'))
            ->with('i', (request()->input('page', 1) - 1) * 5);
    }

    /**
     * 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 created successfully.');
    }

    /**
     * Display the specified resource.
     *
     * @param  \App\Models\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\Models\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\Models\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\Models\Post  $post
     * @return \Illuminate\Http\Response
     */
    public function destroy(Post $post)
    {
        $post->delete();
    
        return redirect()->route('posts.index')
                        ->with('success','Post deleted successfully');
    }
}

Ok, so after run bellow command you will find "app/Models/Post.php" and put bellow content in Post.php file:

namespace App\Models;

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

class Post extends Model
{
    use HasFactory;

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

Step - 6 : Add Blades Files

In the last step, we need to create all the blade files for post listing, post creates, post an update, so, create the four-blade file in our laravel application.

• 1) resources/views/posts/layout.blade.php
• 2) resources/views/posts/index.blade.php
• 3) resources/views/posts/create.blade.php
• 4) resources/views/posts/edit.blade.php
• 5) resources/views/posts/show.blade.php
