How to make CRUD Laravel 8 clean Code for beginner
Hello everybody, I write a tutorial about How to make CRUD laravel 8
if you have trouble learning laravel this tutorial is perfect for you
okee first we can install laravel with code in the below
so before you install laravel with this code make sure you have composer installed in your computer
first
composer create-project — prefer-dist laravel/laravel project_name
if you are using xampp, go to the folder xampp/htdoc/project_name
and open the folder app
if you are using Laragon, go to the folder laragon/www/project_name
Open this app, I use Visual studio code for this text editor
Next we can open cmd and start the app with
php artisan serve
Wow amazing app,
next we can start make model,controller and database in the same time with this magic code
php artisan make:model Post -mc
we can add -mc (M for model and C for controller)
open folder if you want to see model
Model : app/models/Post.php
Controller : app/Http/controllers/PostController.php
Migration : database/migrations/2021_10_07_032242_create_posts_table
Oke let’s start make sure you have created a database
change .env file and search DB_DATABASE= your database
Open migration file and change like below :
<?php
use Illuminate\Database\Migrations\Migration;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Support\Facades\Schema;class CreatePostsTable extends Migration
{
/**
* Run the migrations.
*
* @return void
*/
public function up()
{
Schema::create(‘posts’, function (Blueprint $table) {
$table->id();
$table->string(‘title’);
$table->text(‘post_content’);
$table->timestamps();
});
}/**
* Reverse the migrations.
*
* @return void
*/
public function down()
{
Schema::dropIfExists(‘posts’);
}
}
let’s start with this code to make migration
php artisan migrate
oke we have created tables
you can check to your database there is multiple tables.
next add property in model Post.php
Add protected $guarded = [];
<?php
namespace App\Models;
use Illuminate\Database\Eloquent\Factories\HasFactory;
use Illuminate\Database\Eloquent\Model;
class Post extends Model
{
use HasFactory;
protected $guarded = [];
}
Oke next to write code
open your browser with link like http://127.0.0.1:8000
oke we have opened laravel project, oke next
open route file : routes/web.php
change with this
I just add namespace for the route like this
namespace App\Http\Controllers;
<?php
namespace App\Http\Controllers;
use Illuminate\Support\Facades\Route;
Route::get(‘/’, function () {
return view(‘welcome’);
});
Route::get(‘/post’,[PostController::class,’index’])->name(‘post.index’);
Route::get(‘/post/create’,[PostController::class,’create’])->name(‘post.create’);
Route::post(‘/post’,[PostController::class,’store’])->name(‘post.store’);
Route::get(‘/post/{post}/edit’,[PostController::class,’edit’])->name(‘post.edit’);
Route::put(‘/post/{post}/update’,[PostController::class,’update’])->name(‘post.update’);
Route::delete(‘/post/{post}/delete’,[PostController::class,’destroy’])->name(‘post.destroy’);
next open PostController.php
change to this :
Code : copy this text to your text editor
<?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(‘post.index’,compact(‘posts’));
}
public function create()
{
return view(‘post.create’);
}
public function store(Request $request)
{
$this->validate($request,[
‘title’ => ‘required’,
‘post_content’ => ‘required’
]);
$data = $request->all();
Post::create($data);
return redirect()->route(‘post.index’)->with(‘success’,’Success created post’);
}
public function edit(Request $request,Post $post)
{
return view(‘post.edit’,compact(‘post’));
}
public function update(Request $request,Post $post)
{
$this->validate($request,[
‘title’ => ‘required’,
‘post_content’ => ‘required’
]);
$data = $request->all();
$post->update($data);
return redirect()->route(‘post.index’)->with(‘success’,’Success updated post’);
}
public function destroy(Request $request,Post $post)
{
if($post){
$post->delete();
return redirect()->route(‘post.index’)->with(‘success’,’Success deleted post’);
}
}
}
Next, I can make content with dynamic content with @yield
open folder resources/views/ create folder post
resources/views/post
again, create folder layouts inside views
the structure is like this
And then create file like below
first open folder layouts/app.php
I use bootstart 4 for UI you can copy in the link below
!DOCTYPE html>
<html lang=”en”>
<head>
<meta charset=”UTF-8">
<meta name=”viewport” content=”width=device-width, initial-scale=1.0">
<meta http-equiv=”X-UA-Compatible” content=”ie=edge”>
<link rel=”stylesheet” href=”https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0/css/bootstrap.min.css" integrity=”sha384-Gn5384xqQ1aoWXA+058RXPxPg6fy4IWvTNh0E263XmFcJlSAwiGgFAW/dAiS6JXm” crossorigin=”anonymous”>
<title>Post CRUD</title>
</head>
<body>
// yield for dynamic content
@yield(‘content’)
<script src=”https://code.jquery.com/jquery-3.2.1.slim.min.js" integrity=”sha384-KJ3o2DKtIkvYIK3UENzmM7KCkRr/rE9/Qpg6aAZGJwFDMVNA/GpGFF93hXpG5KkN” crossorigin=”anonymous”></script>
<script src=”https://cdnjs.cloudflare.com/ajax/libs/popper.js/1.12.9/umd/popper.min.js" integrity=”sha384-ApNbgh9B+Y1QKtv3Rn7W3mgPxhU9K/ScQsAP7hUibX39j7fakFPskvXusvfa0b4Q” crossorigin=”anonymous”></script>

</body>
</html>
Next step, open index file in the post folder resources/views/post/index.blade.php
change with this :
I use @extends call to layouts.app
and and to add content to yield we can use @section(‘content’)
Code :
@extends(‘layouts.app’)
@section(‘content’)
<section class=”container”>
@if (Session::has(‘success’))
<div class=”alert alert-success mt-3">
{{ Session::get(‘success’) }}
</div>
@endif
<div class=”card mt-5">
<div class=”card-header”>
<h5>Data Post</h5>
</div>
<div class=”card-body”>
<a href=”{{ route(‘post.create’) }}” class=”btn btn-success mb-3">+ Create Post</a>
<div class=”table-responsive”>
<table class=”table table-striped table-inverse table-responsive d-table”>
<thead>
<tr>
<th>No</th>
<th>Title</th>
<th>Content</th>
<th>Action</th>
</tr>
</thead>
<tbody>
<?php $no = 1; ?>
@forelse ($posts as $post)
<tr>
<td>{{ $no++ }}</td>
<td>{{ $post->title }}</td>
<td>{{ $post->post_content }}</td>
<td>
<a href=”{{ route(‘post.edit’,$post) }}” class=”btn btn-warning btn-sm”>Edit</a>
<form action=”{{ route(‘post.destroy’,$post) }}” method=”post” style=”display: contents;”>
@csrf
@method(‘DELETE’)
<button type=”submit” class=”btn btn-danger btn-sm”>Delete</button>
</form>
</td>
</tr>
@empty
<tr>
<td colspan=”4">No data.</td>
</tr>
@endforelse
</tbody>
</table>
</div>
</div>
</div>
</section>
@endsection
Next step, open create file in the post folder resources/views/post/create.blade.php
Change like this :
Code :
@extends(‘layouts.app’)
@section(‘content’)
<section class=”container”>
<div class=”card mt-5">
<div class=”card-header”>
<h5>Create Post</h5>
</div>
<div class=”card-body”>
@if ($errors->any())
<div class=”alert alert-danger”>
<ul>
@foreach ($errors->all() as $error)
<li>{{ $error }}</li>
@endforeach
</ul>
</div>
@endif
<form action=”{{ route(‘post.store’) }}” method=”post”>
@csrf
<div class=”form-group”>
<label for=””>Title</label>
<input type=”text” name=”title” value=”{{ old(‘title’) }}” class=”form-control” placeholder=”Title Post”>
</div>
<div class=”form-group”>
<label for=””>Post Content</label>
<textarea name=”post_content” value=”{{ old(‘post_content’) }}” class=”form-control” placeholder=”Post Content”></textarea>
</div>
<button type=”submit” class=”btn btn-success”>CREATE</button>
</form>
</div>
</div>
</section>
@endsection
Last step, open edit file in the post folder resources/views/post/edit.blade.php
Code like below :
@extends(‘layouts.app’)
@section(‘content’)
<section class=”container”>
<div class=”card mt-5">
<div class=”card-header”>
<h5>Update Post</h5>
</div>
<div class=”card-body”>
@if ($errors->any())
<div class=”alert alert-danger”>
<ul>
@foreach ($errors->all() as $error)
<li>{{ $error }}</li>
@endforeach
</ul>
</div>
@endif
<form action=”{{ route(‘post.update’,$post) }}” method=”post”>
@method(‘PUT’)
@csrf
<div class=”form-group”>
<label for=””>Title</label>
<input type=”text” name=”title” value=”{{ old(‘title’,$post->title) }}” class=”form-control” placeholder=”Title Post”>
</div>
<div class=”form-group”>
<label for=””>Post Content</label>
<textarea name=”post_content” value=”” class=”form-control” placeholder=”Post Content”>{{ old(‘post_content’,$post->post_content) }}</textarea>
</div>
<button type=”submit” class=”btn btn-success”>UDPATE</button>
</form>
</div>
</div>
</section>
@endsection
Oke finish, you just created a laravel project with clean code, but I don’t use the route resource, if you want to use it, you can use a code like this
php artisan make:controller PostController -r
and then route file just
Route::resource(‘post’,PostController::class);
oke, Thank you for reading this tutorial, hopefully friends are always healthy and happy. See you next tutorial
