I’m going to show you about laravel 9 crud operation from scratch. this example will help you with information about Laravel 9 CRUD Example – Laravel 9 CRUD Beginners Tutorial.

In this post, we will give you information about Laravel 9 CRUD Example – Laravel 9 CRUD Beginners Tutorial. Here we will give you detail about Laravel 9 CRUD Example | Laravel 9 CRUD Beginners Tutorial And how to use it also give you a demo for it if it is necessary.

In this example, we will create a post-crud operation using laravel 9. we will create a posts table with title and body column using laravel 9 migration, then we will create routes, controller, view, and model files for the post module.

Let's start following step by step example:

Step 1: Download Laravel


Let us begin the tutorial by installing a new laravel application. if you have already created the project, then skip following step.

composer create-project laravel/laravel example-app

Step 2: Add Database Configuration

After the complete installation of laravel. we have to database configuration. now we will open the .env file and change the database name, username, password in the .env file. See below changes in a .env file.

.env

DB_CONNECTION=mysql

DB_HOST=127.0.0.1

DB_PORT=3306

DB_DATABASE=your-database-name

DB_USERNAME=your-database-user-name

DB_PASSWORD=your-database-password

Step 3: Add Table using migration

Create Post Model & Migration For Laravel 9 CRUD Application.

Open again your command prompt. And run the following command on it.

php artisan make:migration create_posts_table --create=posts

After that, open create_posts_table.php file inside LaravelCRUD/database/migrations/ directory. And the update the function up() with following code:

<?php

use Illuminate\Database\Migrations\Migration;

use Illuminate\Database\Schema\Blueprint;

use Illuminate\Support\Facades\Schema;

return new class extends Migration

{

/**

* Run the migrations.

*

* @return void

*/

public function up()

{

Schema::create('posts', function (Blueprint $table) {

$table->bigIncrements('id');

$table->string('title');

$table->text('body');

$table->timestamps();

});

}

/**

* Reverse the migrations.

*

* @return void

*/

public function down()

{

Schema::dropIfExists('posts');

}

};

php artisan migrate

Step 4: Add Resource Route

We have to need put below student resource route in routes/web.php

<?php

use Illuminate\Support\Facades\Route;

use App\Http\Controllers\PostController;

/*

|--------------------------------------------------------------------------

| Web Routes

|--------------------------------------------------------------------------

|

| Here is where you can register web routes for your application. These

| routes are loaded by the RouteServiceProvider within a group that

| contains the "web" middleware group. Now create something great!

|

*/

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

Step 5: Add Model and Controller

Here below command help to create the controller and model.

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

Post.php

<?php

namespace App\Models;

use Illuminate\Database\Eloquent\Factories\HasFactory;

use Illuminate\Database\Eloquent\Model;

class Post extends Model

{

use HasFactory;

protected $fillable = [

'title', 'body'

];

}

PostController.php

<?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()

{

$post = Post::latest()->get();

return view('post.index',compact('post'))

->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('post.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',

'body' => '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('post.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('post.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',

'body' => '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');

}

}

Step 6: Add Blade Files

1) layout.blade.php

2) index.blade.php

3) create.blade.php

4) edit.blade.php

5) show.blade.php

So let's just create the following file and put bellow code.

resources/views/post/layout.blade.php

<!DOCTYPE html>

<html>

<head>
