Hi Dev,

This post is focused on laravel livewire crud example. This tutorial will give you simple example of crud application using livewire laravel example. we will help you to give example of laravel 7 livewire tutorial example. you can understand a concept of livewire crud laravel example.

Here, i will give you step by step crud operation using livewire in laravel 6, laravel 7, laravel 8 and laravel 9 example. you have to just follow few step to done this example.

Livewire is a full-stack framework for Laravel framework that makes building dynamic interfaces simple, without leaving the comfort of Laravel. if you are using livewire with laravel then you don't worry about writing jquery ajax code, livewire will help to write very simple way jquery ajax code using php. without page refresh laravel validation will works, form will submit etc.

In this example we will create post insert update delete module. we will take title and body as post field and you can create post, update post and delete that post.

So, let's follow bellow step and you will get bellow layout:

List View:

Create View:

Update View:

Step 1: Install Laravel

first of all we need to get fresh Laravel version application using bellow command, So open your terminal OR command prompt and run bellow command:

composer create-project laravel/laravel livewire

Step 2: Create Migration and Model

Here, we need create database migration for "posts" table and also we will create 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 we will create "Post" model by using 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

now in this step, we will simply install livewire to our laravel application using bellow command:

composer require livewire/livewire

Step 4: Create Post Component

Now here we will create livewire component using their command. so run bellow command to create post crud application component.

php artisan make:livewire posts

Now they created fies on both path:

app/Http/Livewire/Posts.php
resources/views/livewire/posts.blade.php

Step 4: Update Component File

Here, we will write render(), resetInputFields(), store(), edit(), cancel(), update() and delete() method for our crud app.

So, let, update 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, we will update following list of files for our listing page, create page and update page.

So, let's update all the files 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('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 6: Update Welcome Blade File

We will update laravel welcome blade file so it will load crud example on our main url.

here, we will update welcome.blade.php file. in this file we will use @livewireStyles, @livewireScripts and @livewire('contact-form'). so let's add it.

resources/views/welcome.blade.php

<!DOCTYPE html>
<html>
<head>
    <title>Laravel Livewire CRUD - ItSolutionStuff.com</title>
    <link href="https://stackpath.bootstrapcdn.com/bootstrap/4.5.0/css/bootstrap.min.css" rel="stylesheet">
    @livewireStyles
</head>
<body>
    <div class="container">
        <div class="row justify-content-center">
            <div class="col-md-8">
                <div class="card">
                    <div class="card-header">
                        <h2>Laravel Livewire CRUD - ItSolutionStuff.com</h2>
                    </div>
                    <div class="card-body">
                        @if (session()->has('message'))
                            <div class="alert alert-success">
                                {{ session('message') }}
                            </div>
                        @endif
                        @livewire('posts')
                    </div>
                </div>
            </div>
