Forum laravel 4.2 custom observer event

posted 10 years ago

Hi every body. I have a directory under my app folder named observers and I listen for various events such as created , updated , ... and I handle them ! my observer events bootstrap is in my model boot function ! for example I have User Model under models folder and I have UserObserver under observers folder! now I need to add my specific event to eloquent observer ! consider I want fire event when one column such as "enable" of my user table has changed. I know I should extend eloquent Model and add a function like userchangestate() coz I already have looked up Eloquent Model it has a function for every event ('creating' , 'created' , 'saving' , 'saved' , ....) but still I'm not sure how handle it ! thanks !

Solution

thanks to http://stackoverflow.com/users/1010632/david-barker now I got the answer : this is my observer :

class NewsObserver {

protected $events;

public function __construct(Dispatcher $dispatcher)
{
    $this->events = $dispatcher;
}

public function saving($model)
{
    if ($model->isDirty(['publish']))
    {
        $this->changeState($model->publish);
    }
}	

public function changeState($value)
{
    echo 'event fired and I got it';
}

}

and this is my model

use Illuminate\Events\Dispatcher; class News extends Magniloquent {

protected $fillable = [];
public $table = 'news';


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

    News::observe(new NewsObserver(new Dispatcher));
}
