[SOLVED]Validation Requirement

Yii 1.1 General Discussion

Hi,

I have a rather complex validation requirement.

A Portfolio must have at least one image associated with it. If there isn’t an image associated with it, I need to make the File Input required. Once the user has submitted a file I need to validate it against CFileValidator.

Pseudo Code:




    public function rules()

    {

        // NOTE: you should only define rules for those attributes that

        // will receive user inputs.

        return array(

            array('imageList', 'validateFile', 'on' => 'manageImages');

    }


    public function validateFile()

    {

        $fileValidator = CValidator::createValidator('CFileValidator', $this, 'imageList');


        if (count($this->images) === 0)

        {

            CMap::mergeArray($this->rules(),

                    array(array('imageList', 'file', 'types' => 'jpg, gif, png',

                            'allowEmpty' => false, 'maxFiles' => 4)));

        }

        else

        {

            CMap::mergeArray($this->rules(),

                    array(array('imageList', 'file', 'types' => 'jpg, gif, png',

                            'allowEmpty' => true, 'maxFiles' => 4)));

        }


        $fileValidator->validate($this, array('imageList'));

    }

Notice that if there are no images associated with the Portfolio, allowEmpty = false.

Could someone point me in the right direction to get this started?

Cheers.

Like most things with Yii, I solved it with a simple solution:




public function rules()

    {

        // NOTE: you should only define rules for those attributes that

        // will receive user inputs.

        return array(

            array('imageList', 'file', 'types' => 'jpg, gif, png',

                'allowEmpty' => $this->isFileRequired(), 'maxFiles' => 4, 'on' => 'manageImages',

                'message' => 'Please select image(s) to upload'),

        );

    }


    public function isFileRequired()

    {

        if (count($this->images) == 0)

            return false;

        else

            return true;

    }

Cheers
