Question

I’m trying to validate a field if a file fields is not empty. So if someone is trying to upload a file, I need to validate another field to make sure they selected what they are uploading, however I don’t know how to check to see, or run a rule only if the field is not empty.

public function rules()
{
    // NOTE: you should only define rules for those attributes that
    // will receive user inputs.
    return array(
        array('full_name, gender_id','required'),
        array('video', 'file', 'types'=>'mp4', 'allowEmpty' => true),
        array('audio', 'file', 'types'=>'mp3', 'allowEmpty' => true),
        array('video','validateVideoType'),
    );
}

public function validateVideoType() {
    print_r($this->video);
    Yii::app()->end();
}

So this->video is always empty whether I just uploaded something or not. How do I check to see if that variable is set?

Answer 1

Custom validation function must be defined properly. It has two parameters always $attribute & $params.

public function validateVideoType($attribute, $params) {
    print_r($this->video);
    Yii::app()->end();
}

Now in this you should write your custom way to validate.
I am sure that would work fine.
