Repeat Password does not work in Yii2

Question

I have written rules in the model as:

    public $password_repeat;

/**
 * @inheritdoc
 */
public function rules()
{
    return [
        ....
        ....  
        ['password', 'required'],
        ['password', 'string', 'min' => 6],
        ['password_repeat', 'compare', 'compareAttribute'=>'password', 'message'=>"Passwords don't match" ],
    ];
}

If I use different password in Password and Password Repeat field, it gives error. So, that's mean it works. But problem is that, it does not give any error if Password Repeat field is empty.

Answer 1

Add a required tag for password_repeat as well. Shown below

return [
        ....  
        ['password', 'required'],
        ['password', 'string', 'min' => 6],
        ['password_repeat', 'required'],
        ['password_repeat', 'compare', 'compareAttribute'=>'password', 'message'=>"Passwords don't match" ],
    ];
