Download New Laravel Project

First of all we need to create a fresh laravel project, download and install Laravel 8 using the below command

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

1	composer create-project --prefer-dist laravel/laravel laravel-demo

Update Database Details

Now, lets create a MySQL database and connect it with laravel application. After creating database we need to set database credential in application’s .env file.

DB_CONNECTION=mysql
DB_HOST=127.0.0.1
DB_PORT=3306
DB_DATABASE=DB_Name
DB_USERNAME=DB_Username
DB_PASSWORD=DB_Password

DB_CONNECTION=mysql

DB_HOST=127.0.0.1

DB_PORT=3306

DB_DATABASE=DB_Name

DB_USERNAME=DB_Username

DB_PASSWORD=DB_Password

Create Migration and Model

Now, in this step we will create model and migration file. Please run the following command:

php artisan make:model Blog -m

1	php artisan make:model Blog -m

Now open app/Models/Blog.php file, and define the values that you want to add in database table.

<?php

namespace App\Models;

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


class Blog extends Model
{
    use HasFactory;
    
    protected $fillable = [ 
        'title', 
        'slug',
        'details' 
    ];

    public $timestamps = false;

    protected static function boot()
    {
        parent::boot();
        static::created(function ($blog) {
            $blog->slug = $blog->initSlug($blog->title);
            $blog->save();
        });
    }

    private function initSlug($title)
    {
        if (static::whereSlug($slug = Str::slug($title))->exists()) {
            $max = static::whereName($title)->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}-1";
        }

        return $slug;
    }
}

<?php

namespace App\Models;

use Illuminate\Support\Str;

use Illuminate\Database\Eloquent\Factories\HasFactory;

use Illuminate\Database\Eloquent\Model;

class Blog extends Model

{

use HasFactory;

protected $fillable = [

'title',

'slug',

'details'

];

public $timestamps = false;

protected static function boot()

{

parent::boot();

static::created(function ($blog) {

$blog->slug = $blog->initSlug($blog->title);

$blog->save();

});

}

private function initSlug($title)

{

if (static::whereSlug($slug = Str::slug($title))->exists()) {

$max = static::whereName($title)->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}-1";

}

return $slug;

}

Open create_blogs_table.php migration file and update the function up() method as following:

<?php

use Illuminate\Database\Migrations\Migration;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Support\Facades\Schema;

class CreateBlogsTable extends Migration
{
    /**
     * Run the migrations.
     *
     * @return void
     */
    public function up()
    {
        Schema::create('blogs', function (Blueprint $table) {
            $table->id();
            $table->string('title', 120);
            $table->string("slug", 120);
            $table->text('details');             
            $table->timestamps();
        });
    }

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

<?php

use Illuminate\Database\Migrations\Migration;

use Illuminate\Database\Schema\Blueprint;

use Illuminate\Support\Facades\Schema;

class CreateBlogsTable extends Migration

{

/**

* Run the migrations.

* @return void

public function up()

{

Schema::create('blogs', function (Blueprint $table) {

$table->id();

$table->string('title', 120);

$table->string("slug", 120);

$table->text('details');

$table->timestamps();

});

}

/**

* Reverse the migrations.

* @return void

public function down()

{

Schema::dropIfExists('blogs');

}

Create Controller File

Now, lets create a controller named BlogController using command given below –

php artisan make:controller BlogController

1	php artisan make:controller BlogController

Once the above command executed, it will create a controller file BlogController.php in app/Http/Controllers/ directory. Open the BlogController.php file and put the following code in it.

app/Http/Controllers/BlogController.php

<?php

namespace App\Http\Controllers;
use Illuminate\Http\Request;
use App\Models\Blog;


class BlogController extends Controller
{
    public function index()
    {
        $blog = Blog::create([
            "title" => "The demo is in process",
            "slug" => "laravel-multiple-slug-urls-example",
            "details" => "Here is the slug demo"
        ]);

        dd($blog);
    }

}

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;

use App\Models\Blog;

class BlogController extends Controller

{

public function index()

{

$blog = Blog::create([

"title" => "The demo is in process",

"slug" => "laravel-multiple-slug-urls-example",

"details" => "Here is the slug demo"

]);

dd($blog);

}

Register New Route

After this, we need to define routes in “routes/web.php” file. Lets open “routes/web.php” file and add the following routes in it.

routes/web.php

<?php

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

/*
|--------------------------------------------------------------------------
| Web Routes
|--------------------------------------------------------------------------
*/

Route::get('/blog', [BlogController::class, 'index']);

<?php

use Illuminate\Support\Facades\Route;

use App\Http\Controllers\BlogController;

|--------------------------------------------------------------------------

| Web Routes

|--------------------------------------------------------------------------

Route::get('/blog', [BlogController::class, 'index']);

Run Development Server

Now we are ready to run our example so lets start the development server using following artisan command –

php artisan serve

1	php artisan serve

Now, open the following URL in browser to see the output –

http://127.0.0.1:8000/blog

1	http://127.0.0.1:8000/blog
