php - yii2 user-defined validation of mobile number -


i new yii2. want validate mobile number custom validation function. how can validate mobile no in yii2 , how can use user-defined rule yii2 , how can add error message attribute in yii2 after form post? in advance

you need edit model. lets have following model:

class user extends activerecord implements identityinterface {     ...  /**  * @inheritdoc  */ public function rules() {     return [         [['email', 'password', 'id'], 'required'],         [['email', 'username'], 'unique'],         ['mobile', 'customvalidation'] //<----this custom validation }  public function customvalidation(){     //perform validation here     if(/*has error*/){         $this->adderror("mobile","your mobile number not valid.");     } }   }

the adderror method's first parameter atribute want add error , second parameter message want show.

hope helps ;)
