Sometime we need to create slug from title with your application. but you also need to create unique slug on that table. might be user will enter same title then it should automatically generate unique slug. i will give you simple example step by step how to generate unique slug in laravel using eloquent model events.

Let's see step by step to create unique slug in laravel example:

app/Models/Product.php

<?php
  
namespace App\Models;
  
use Illuminate\Database\Eloquent\Factories\HasFactory;
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;
                }, $max);
            }
  
            return "{$slug}-2";
        }
  
        return $slug;
    }
}

Controller Code:

<?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);
    }
}

now if you create multiple time same title record then it will create slug as bellow:

laravel-8-image-upload
laravel-8-image-upload-2
laravel-8-image-upload-3
laravel-8-image-upload-4

now you can try it and check it.

i hope it can help you...
