Websolutionstuff | Nov-24-2022 | Categories : Laravel PHP

In this article, we will see the laravel 9 livewire crud operation. we will learn about livewire crud operation in laravel 9 and how to create crud operation using livewire in laravel 9. Also, see how to install livewire in laravel 9. In this laravel 9 application, we will perform insert, update delete functionalities without page refresh.

Livewire is a full-stack framework for Laravel that makes building dynamic interfaces simple, without leaving the comfort of Laravel. Livewire makes an AJAX request to the server with the updated data. The server re-renders the component and responds with the new HTML.

So, let's see the livewire crud in laravel 9, and how to create a livewire crud operation in laravel 9.

 

Laravel 9 CRUD Operation Using Livewire

 

Step 1: Install Laravel 9

In this step, we will install the laravel 9 application using the following command.

composer create-project laravel/laravel laravel_9_livewire_crud_example

 

Step 2: Create Migration and Model

Now, we will create a post table and model. So, we will create migration and Post model.

php artisan make:migration create_posts_table

 

 

<?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');
    }
};

Now, we will migrate the posts table using the following command.

php artisan migrate

Now, we will create Post Model using the below 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

In this step, we will install the livewire package using the composer command.

composer require livewire/livewire

 

 

Step 4: Create Post Component

Now, we will create a livewire posts component using the following command. So, run the below command in the terminal and create a crud operation.

php artisan make:livewire posts

 

Step 5: Update Component File

In this step, we will update the Posts.php 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()
    {
        $validatedData = $this->validate([
            'title' => 'required',
            'body' => 'required',
        ]);
  
        Post::create($validatedData);
  
        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()
    {
        $validatedData = $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 6: Update Blade Files

In this step, we will update the posts.blade.php file. we will update the listing page, create page, and update page.

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('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="update()" class="btn btn-dark">Update</button>
    <button wire:click.prevent="cancel()" class="btn btn-danger">Cancel</button>
</form>

 
Step 7: Update Welcome Blade File

In this step, we will update the welcome.blade.php file and in this file, we will include the livewire style, livewire script, and form.

resources/views/welcome.blade.php
