use Illuminate\Database\Eloquent\Model;

use Illuminate\Support\Str;

class Product extends Model

{

use HasFactory;

protected $fillable = [

'title', 'detail', 'slug'

];

/**

* Boot the model.

*/

protected static function boot()

{

parent::boot();

static::created(function ($product) {

$product->slug = $product->createSlug($product->title);

$product->save();

});

}

/**

* Write code on Method

*

* @return response()

*/

private function createSlug($title){

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

$max = static::whereTitle($title)->latest('id')->skip(1)->value('slug');

if (is_numeric($max[-1])) {

return preg_replace_callback('/(\d+)$/', function ($mathces) {

return $mathces[1] + 1;

<?php

namespace App\Http\Controllers;

use App\Models\Product;

use Illuminate\Http\Request;

class ProductController extends Controller

{

/**

* Display a listing of the resource.

*

* @return \Illuminate\Http\Response

*/

public function index()

{

$product = Product::create([

"title" => "Laravel 8 Image Upload"

]);

dd($product);

}

}
