Yii form model validation- either one is required

Question

I have two fields on the form ( forgotpassword form ) username and email Id . User should enter one of them . I mean to retrieve the password user can enter user name or the email id . Could some one point me the validation rule for this?

Is there any inbuilt rule I can use?

I was trying to solve same problem today. What I've got is the code below.

public function rules()
{
    return array(
        // array('username, email', 'required'), // Remove these fields from required!!
        array('email', 'email'),
        array('username, email', 'my_equired'), // do it below any validation of username and email field
    );
}

public function my_required($attribute_name, $params)
{
    if (empty($this->username)
            && empty($this->email)
    ) {
        $this->addError($attribute_name, Yii::t('user', 'At least 1 of the field must be filled up properly'));

        return false;
    }

    return true;
}

General idea is to move 'required' validation to custom my_required() method which can check if any of field is filled up.

I see this post is from 2011 however I couldn't find any other solution for it. I Hope it will work for you or other in the future.

Enjoy.
