laravel model event static call issue - events

Question

Why my static method don´t work with a varible class?
/**
* Events
*/
public static function boot() {
parent::boot();
$class = get_called_class(); // The value os $class is: Product ( string)
// This work
Product::creating(function($model) {
return $model->validate();
});
// Don´t work, the closure never called!
$class::creating(function($model) {
return $model->validate();
});
$class::updating(function($model) {
return $model->validate(true);
});
}
Incredible, this work to:
$class = "Product"; //get_called_class();
Solution ( Not elegant , but ... )
On my Product model i put this, to share class name with Base model.
public static function boot() {
parent::$cls = "Product";
parent::boot();
}
but updating does not work yet!

Answer 1

Actually (since PHP 5.3) it should work to do:
$class = 'Product';
$class::creating(function($model){
return $model->validate();
});
But why not just use static:: to access the current class? This way you don't need get_called_class:
static::creating(function($model){
return $model->validate();
});
There's also call_user_func if everything else fails...
