Laravel 9 Livewire CRUD

Hello Dev, Today now in this i will give you an example of laravel 9 livewire crud example. From here you can understand a concept of crud application by using the livewire laravel 9 example. we can understand a concept of laravel 9 livewire tutorial example. So let’s discuss about the livewire crud laravel 9 example.

Alright, let’s dive into the steps.

Step 1: Install Laravel 9

At first of all we have to get the fresh Laravel version application by using the bellow command. So open your terminal OR command prompt and then run the bellow command:

composer create-project laravel/laravel livewire
Step 2: Create Migration and Model

Here, i have to create the database migration for “posts” table and also i will create the model for files table.

php artisan make:migration create_posts_table

Migration:

<?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->id();
            $table->string('title');
            $table->text('body');
            $table->timestamps();
        });
    }
  
    /**
     * Reverse the migrations.
     *
     * @return void
     */
    public function down()
    {
        Schema::dropIfExists('posts');
    }
};
php artisan migrate

now i will be create “Post” model by using the following command:

php artisan make:model Post

App/Models/Post.php

<?php
  
namespace App\Models;
  
use Illuminate\Database\Eloquent\Factories\HasFactory;
use Illuminate\Database\Eloquent\Model;
  
class Post extends Model
{
    use HasFactory;
  
    /**
     * The attributes that are mass assignable.
     *
     * @var array
     */
    protected $fillable = [
        'title', 'body'
    ];
}
Step 3: Install Livewire

So now in this step, i will simply install the livewire to our laravel application by using the bellow command:

composer require livewire/livewire
Step 4: Create Post Component

Now here i will create the livewire component by using their command. So just run the bellow command to create post crud application component.

php artisan make:livewire posts

Now it will created fies on both path:

app/Http/Livewire/Posts.php
resources/views/livewire/posts.blade.php
Step 4: Update Component File

Here, i will be write render(), resetInputFields(), store(), edit(), cancel(), update() and delete() method for my crud application.

So, let, update the following file.

app/Http/Livewire/Posts.php

<?php
  
namespace App\Http\Livewire;
  
use Livewire\Component;
use App\Models\Post;
  
class Posts extends Component
{
    public $posts, $title, $body, $post_id;
    public $updateMode = false;
   
    /**
     * The attributes that are mass assignable.
     *
     * @var array
     */
    public function render()
    {
        $this->posts = Post::all();
        return view('livewire.posts');
    }
  
    /**
     * The attributes that are mass assignable.
     *
     * @var array
     */
    private function resetInputFields(){
        $this->title = '';
        $this->body = '';
    }
   
    /**
     * The attributes that are mass assignable.
     *
     * @var array
     */
    public function store()
    {
        $validatedDate = $this->validate([
            'title' => 'required',
            'body' => 'required',
        ]);
  
        Post::create($validatedDate);
  
        session()->flash('message', 'Post Created Successfully.');
  
        $this->resetInputFields();
    }
  
    /**
     * The attributes that are mass assignable.
     *
     * @var array
     */
    public function edit($id)
    {
        $post = Post::findOrFail($id);
        $this->post_id = $id;
        $this->title = $post->title;
        $this->body = $post->body;
  
        $this->updateMode = true;
    }
  
    /**
     * The attributes that are mass assignable.
     *
     * @var array
     */
    public function cancel()
    {
        $this->updateMode = false;
        $this->resetInputFields();
    }
  
    /**
     * The attributes that are mass assignable.
     *
     * @var array
     */
    public function update()
    {
        $validatedDate = $this->validate([
            'title' => 'required',
            'body' => 'required',
        ]);
  
        $post = Post::find($this->post_id);
        $post->update([
            'title' => $this->title,
            'body' => $this->body,
        ]);
  
        $this->updateMode = false;
  
        session()->flash('message', 'Post Updated Successfully.');
        $this->resetInputFields();
    }
   
    /**
     * The attributes that are mass assignable.
     *
     * @var array
     */
    public function delete($id)
    {
        Post::find($id)->delete();
        session()->flash('message', 'Post Deleted Successfully.');
    }
}
Step 5: Update Blade Files

Here, i will be update the following list of files for our listing page, create page and then update page.

So, let’s update all the files as like as bellow:

resources/views/livewire/posts.blade.php

<div>
  
    @if (session()->has('message'))
        <div class="alert alert-success">
            {{ session('message') }}
        </div>
    @endif
  
    @if($updateMode)
        @include('livewire.update')
    @else
        @include('livewire.create')
    @endif
  
    <table class="table table-bordered mt-5">
        <thead>
            <tr>
                <th>No.</th>
                <th>Title</th>
                <th>Body</th>
                <th width="150px">Action</th>
            </tr>
        </thead>
        <tbody>
            @foreach($posts as $post)
            <tr>
                <td>{{ $post->id }}</td>
                <td>{{ $post->title }}</td>
                <td>{{ $post->body }}</td>
                <td>
                <button wire:click="edit({{ $post->id }})" class="btn btn-primary btn-sm">Edit</button>
                    <button wire:click="delete({{ $post->id }})" class="btn btn-danger btn-sm">Delete</button>
                </td>
            </tr>
            @endforeach
        </tbody>
    </table>
</div>
resources/views/livewire/create.blade.php
<form>
    <div class="form-group">
        <label for="exampleFormControlInput1">Title:</label>
        <input type="text" class="form-control" id="exampleFormControlInput1" placeholder="Enter Title" wire:model="title">
        @error('title') <span class="text-danger">{{ $message }}</span>@enderror
    </div>
    <div class="form-group">
        <label for="exampleFormControlInput2">Body:</label>
        <textarea type="email" class="form-control" id="exampleFormControlInput2" wire:model="body" placeholder="Enter Body"></textarea>
        @error('body') <span class="text-danger">{{ $message }}</span>@enderror
    </div>
    <button wire:click.prevent="store()" class="btn btn-success">Save</button>
</form>
resources/views/livewire/update.blade.php
<form>
    <input type="hidden" wire:model="post_id">
    <div class="form-group">
        <label for="exampleFormControlInput1">Title:</label>
        <input type="text" class="form-control" id="exampleFormControlInput1" placeholder="Enter Title" wire:model="title">

        @error('body') <span class="text-danger">{{ $message }}</span>@enderror
    </div>
    <button wire:click.prevent="update()" class="btn btn-dark">Update</button>

                            </div>
                        @endif
