Laravel 11 CRUD

Creating a CRUD (Create, Read, Update, Delete) application in Laravel 11 involves several steps. Here’s a detailed guide to help you set up a basic CRUD system:

1. Set Up Laravel Project

If you haven`'t already set up a Laravel project, start by creating a new Laravel project:

bash

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


cd laravel-crud

2. Create a Migration

For example, if you’re creating a bb table:

bash

php artisan make:migration create_posts_table --create=posts

Edit the migration file located in database/migrations/xxxx_xx_xx_create_posts_table.php to define the schema:

bash


    // Example migration schema definition
    public function up() {
        Schema::create('posts', function (Blueprint $table) {
            $table->id();
            $table->string('title');
            $table->text('content');
            $table->timestamps();
        });
    }

Run the migration to create the table:

bash

php artisan migrate

3. Create a Model

Generate a model for your table:

bash

php artisan make:model Post

The model file will be located at app/Models/Post.php. Ensure it looks like this:

php

namespace App\
use Illuminate\
Database\
Eloquent\
Factories\
HasFactory;
use Illuminate\
Database\
Eloquent\
Model;
class Postextends Model {
use HasFactory;
protected $fillable = [
'title',
'content'
];
}

4. Create a Controller

Generate a controller to handle CRUD operations:

bash

php artisan make:controller PostController

Edit the controller file located at app/Http/Controllers/PostController.php:

php


    namespace App\Http\Controllers;

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

    class PostController extends Controller {
        public function index() {
            $posts = Post::all();
            return view('posts.index', compact('posts'));
        }

        public function create() {
            return view('posts.create');
        }

        public function store(Request $request) {
            $request->validate([
                'title' => 'required',
                'content' => 'required',
            ]
            Post::create($request->all());
            return redirect()->route('posts.index')->with('success', 'Post created successfully.');
        }

        public function show(Post $post) {
            return view('posts.show', compact('post'));
        }

        public function edit(Post $post) {
            return view('posts.edit', compact('post'));
        }

        public function update(Request $request, Post $post) {
            $request->validate([
                'title' => 'required',
                'content' => 'required',
            ])

            $post->update($request->all());
            return redirect()->route('posts.index')->with('success', 'Post updated successfully.');
        }

        public function destroy(Post $post) {
            $post->delete();
            return redirect()->route('posts.index')->with('success', 'Post deleted successfully.');
        }
    }

5. Define Routes

Add routes for your CRUD operations in routes/web.php:

php

use App\Http\Controllers\PostController;
Route::resource('posts', PostController::class);

6. Create Views

Create Blade templates for your views. Here’s a basic setup:

Index View ( resources/views/posts/index.blade.php):

blade


    <!DOCTYPE html>
    <html lang="en">
        <head>
            <meta charset="UTF-8">
            <meta name="viewport" content="width=device-width, initial-scale=1.0">
            <title>Posts</title>
        </head>
        <body>
            <h1>Posts</h1>
            <a href="{{ route('posts.create') }}">Create New Post</a>
            <table>
                <thead>
                    <tr>
                        <th>Title</th>
                        <th>Actions</th>
                    </tr>
                </thead>
                <tbody>
                    @foreach($posts as $post)
                        <tr>
                            <td>{{ $post->title }}</td>
                            <td>
                                <a href="{{ route('posts.show', $post->id) }}">View</a>
                                <a href="{{ route('posts.edit', $post->id) }}">Edit</a>
                                <form action="{{ route('posts.destroy', $post->id) }}" method="POST" style={{ display: 'inline' }}>
                                    @csrf
                                    @method('DELETE')
                                    <button type="submit">Delete</button>
                                </form>
                            </td>
                        </tr>
                    @endforeach
                </tbody>
            </table>
        </body>
    </html>

Create View ( resources/views/posts/create.blade.php):

blade

<!DOCTYPE html>
    <html lang="en">
        <head>
            <meta charset="UTF-8">
            <meta name="viewport" content="width=device-width, initial-scale=1.0">
            <title>Create Post</title>
        </head>
        <body>
            <h1>Create Post</h1>
            <form action="{{ route('posts.store') }}" method="POST">
                @csrf
                <label htmlFor="title">Title:</label>
                <input type="text" name="title" id="title" required />
                <label htmlFor="content">Content:</label>
                <textarea name="content" id="content" required></textarea>
                <button type="submit">Save</button>
            </form>
        </body>
    </html>

Edit View ( resources/views/posts/edit.blade.php):

blade

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>Edit Post</title>
</head>
<body>
    <h1>Edit Post</h1>
    <form action="{{ route('posts.update', $post->id) }}" method="POST">
        @csrf
        @method('PUT')
        <label htmlFor="title">Title:</label>
        <input type="text" name="title" id="title" value="{{ $post->title }}" required />
        <label htmlFor="content">Content:</label>
        <textarea name="content" id="content" required>{{ $post->content }}</textarea>
        <button type="submit">Update</button>
    </form>
</body>
</html>

Show View ( resources/views/posts/show.blade.php):

blade

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>Show Post</title>
</head>
<body>
    <h1>{{ $post->title }}</h1>
    <div>
        {!! $post->content !!}
    </div>
    <a href="{{ route('posts.edit', $post->id) }}">Edit</a>
    <form action="{{ route('posts.destroy', $post->id) }}" method="POST">
        @csrf
        @method('DELETE')
        <button type="submit">Delete</button>
    </form>
    <a href="{{ route('posts.index') }}">Back to Posts</a>
</body>
</html>
