Generate a unique slug for every post in Laravel

Normally we use post id to show a single post in Laravel. But it’s not SEO-friendly. So I’m going to write a post, on how you can generate a custom slug/URL for every post in your Laravel application. At first, the table field name should be a slug, and the form field name should be the title.

You’ve written the code into your Post model. It’s a first technique. It’ll generate slug like: lorem-ipsum, lorem-ipsum-1, lorem-ipsum-2

/** * Boot the model. */  
 protected static function boot(){  
   parent::boot();  
   static::created(function ($post) {  
   $post->update(['slug' => $post->title]); });  
 }   
 /** * Set the proper slug attribute. * * @param string $value */   
 public function setSlugAttribute($value){   
   if (static::whereSlug($slug = Str::slug($value))->exists()) {   
     $slug = $this->incrementSlug($slug);   
   }  
   $this->attributes['slug'] = $slug;   
 }   
 /** * Increment slug * * @param string $slug * @return string **/  
 public function incrementSlug($slug) {   
   // get the slug of the latest created post   
   $max = static::whereTitle($this->title)->latest('id')->skip(1)->value('slug'); if (is_numeric($max[-1])) {   
     return pred_replace_callback('/(\d+)$/',   
     function ($mathces) {   
       return $mathces[1] + 1;   
     }, $max);   
   } return "{$slug}-2";  
 } 

Second technique. It’ll generate a slug with your post id, like lorem-ipsum-18

 /** * Boot the model. */   
 protected static function boot(){   
   parent::boot();  
   static::created(function ($post) {  
     $post->update(['slug' => $post->title]);   
   });   
 }   
 /** * Set the proper slug attribute * * @param string $value */   
 public function setSlugAttribute($value){   
   if (static::whereSlug($slug = Str::slug($value))->exists()) {   
     $slug = "{$slug}-{$this->id}";   
   }   
   $this->attributes['slug'] = $slug;
