validation du modèle Yii règles

Question

Salut à vous tous de grands développeurs php,

J'ai un problème dans une règle de validation de yu, j'ai créé un formulaire d'inscription avec un code promo pour mon produit. Lorsque l'utilisateur saisit un code promo, je veux vérifier si la valeur est présente dans la table des coupons ou non. Lorsque l'utilisateur saisit le code de validation je souhaite que ma règle de validation fonctionne, sinon l'utilisateur ne saisira pas le code cette règle de validation ne devrait pas fonctionner, pour l'inscription des membres j'ai un modèle membre et pour le coupon j'ai un modèle de coupon J'utilise cette méthode dans les règles de validation.

class MemberSignup extends CActiveRecord 
{ 
    public $couponcode; 

    public function rules(){ 
     array('couponcode', 'isCouponCodeExist'), 
    }//end rules 

    public function isCouponCodeExist($attribute, $params) 
    {  
     $record = Coupon::model()->findByAttributes(array('couponcode' => $this->couponcode)); 

     if($record === null){ 
      $this->addError($attribute, 'Invalid Coupon'); 
      return false; 
     } 

     return true; 
    } 
} //class end 

tout suggesstion sera helpfull pour moi

Answer 1

Si je vous ai bien compris, votre couponcode n'est pas nécessaire et que vous souhaitez valider le couponcode que si l'utilisateur a entré un.

public function rules() 
{ 
    return array(
     array('field1, field2, field3', 'required'), 
     array('couponcode', 'isCouponCodeExist'), 
    ); 
} 

EDIT:

En yu, toutes les méthodes de validation d'un modèle sera exécuté, même si n'est pas nécessaire le champ qui est en cours de validation. Même si votre champ couponcode n'est pas requis, la méthode de validation isCouponCodeExist() sera toujours exécutée.

Cela signifie que nous allons devoir modifier votre code dans la méthode isCouponCodeExist() pour permettre à un couponcode vide, un petit quelque chose comme ceci:

public function isCouponCodeExist($attribute, $params) 
{ 
    if(!empty($this->couponcode)) 
    {  
     $record = Coupon::model()->findByAttributes(array('couponcode' => $this->couponcode)); 

     if($record === null) 
     { 
      $this->addError($attribute, 'Invalid Coupon'); 
     } 
    } 
} 

En outre, vous n'avez pas retourner vrai ou faux méthodes de validation. Tout ce que vous devez faire est d'ajouter une erreur si quelque chose ne va pas.
