How To Generate Multi Unique Slug On Page Load In Laravel 8?

Hi friends,

This example is how to generate multi unique slug on page load in laravel 8?.

We will elaborate how to generate dynamic multiple slug in the Laravel 8 application.

The specific keyword or id denotes the slug. You most probably use it when you want to refer to an item while retaining the ability to see at it.

So let's start following step.

Step 1 - Install Freash Laravel Application

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

Move into laravel app.

cd MyBlog

Step 2 - Set Database Connection

You can use MAMP or XAMPP as a local web server, insert the database name, username and password in the .env file.

DB_CONNECTION=mysql
DB_HOST=localhost
DB_PORT=3306
DB_DATABASE=laravel_db
DB_USERNAME=root
DB_PASSWORD=

Step 3 - Create Model and Migration

In this step, you have to generate model and migration files. It can be done by using a single command, hence execute the following command.

php artisan make:model Post -m

After running the suggested command, new model and migration files have been generated, and you will add values in these files to create a table in the database.

Update code in app/Models/Post.php file.

<?php

namespace App\Models;

use Illuminate\Support\Str;
use Illuminate\Database\Eloquent\Factories\HasFactory;
use Illuminate\Database\Eloquent\Model;

class Post extends Model
{
    use HasFactory;
    
    protected $fillable = [ 
        'name', 
        'slug',
        'description' 
    ];

    public $timestamps = false;

    protected static function boot()
    {
        parent::boot();

        static::created(function ($post) {
            $post->slug = $post->generateSlug($post->name);
            $post->save();
        });
    }

    private function generateSlug($name)
    {
        if (static::whereSlug($slug = Str::slug($name))->exists()) {
            $max = static::whereName($name)->latest('id')->skip(1)->value('slug');
            if (isset($max[-1]) && is_numeric($max[-1])) {
                return preg_replace_callback('/(\d+)$/', function($mathces) {
                    return $mathces[1] + 1;
                }, $max);
            }
            return "{$slug}-2";
        }

        return $slug;
    }    

}

Now, get into the app/database/migrations/create_posts_table.php, and you have to insert the table values into this migration file.

<?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('name', 150);
            $table->string("slug", 150);
            $table->text('description');            
            $table->timestamps();
        });
    }

    /**
     * Reverse the migrations.
     *
     * @return void
     */
    public function down()
    {
        Schema::dropIfExists('posts');
    }
}

Step 4 - Run Database Migration

All the migration and model files have been updated now, and you have to execute the command to run migrations.

php artisan migrate

Step 5 - Create Controller

Let us generate a new controller file using the following composer command.

php artisan make:controller PostController

Next, you have to open the app/Http/Controllers/PostController.php and update the file with the given code.

<?php

namespace App\Http\Controllers;

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

class PostController extends Controller
{

    $post = Post::create([
        "name" => "This is my post",
        "slug" => "laravel-generate-multi-slug-on-load",
        "description" => "This is just the laravel generate multi slug example"
    ]);

    dd('Successfully Slug Store.');

}

Step 6 - Add Route

Now, you need to have a route defined in the routes/web.php file, and this route will be the endpoint or url for generating the slug.

<?php

use Illuminate\Support\Facades\Route;
use App\Http\Controllers\PostController;

/*
|--------------------------------------------------------------------------
| Web Routes
|--------------------------------------------------------------------------
|
| Here is where you can register web routes for your application. These
| routes are loaded by the RouteServiceProvider within a group which
| contains the "web" middleware group. Now create something great!
|
*/

Route::get('/post', [PostController::class, 'index']);

Step 7 - Start Laravel Application

php artisan serve

Then open the browser and type the url on the address bar.

http://localhost:8000/post

Output:

I hope it can help you......
