Perform Validation On An Array

Im trying to perform an validation on an array but not getting the desired results. Here is my modal.


<?php


/**

 * This is the model class for table "userGameNumber".

 *

 * The followings are the available columns in table 'userGameNumber':

 * @property integer $id

 * @property integer $userId

 * @property integer $gameId

 * @property string $number

 * @property integer $megaball

 */

class UserGameNumber extends CActiveRecord

{

	/**

	 * Returns the static model of the specified AR class.

	 * @param string $className active record class name.

	 * @return UserGameNumber the static model class

	 */

	public static function model($className=__CLASS__)

	{

		return parent::model($className);

	}

	

	/**

	 * @return string the associated database table name

	 */

	public function tableName()

	{

		return 'userGameNumber';

	}


	/**

	 * @return array validation rules for model attributes.

	 */

	public function rules()

	{

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

		// will receive user inputs.

		return array(

			array('number, megaball', 'required'),

                        

                          array('number', 'numberCount'),

			array('userId, gameId, megaball', 'numerical', 'integerOnly'=>true),

			array('', 'length', 'max'=>255),

			// The following rule is used by search().

			// Please remove those attributes that should not be searched.

			array('id, userId, gameId, number, megaball', 'safe', 'on'=>'search'),

		);

	}


	/**

	 * @return array relational rules.

	 */

	public function relations()

	{

		// NOTE: you may need to adjust the relation name and the related

		// class name for the relations automatically generated below.

		return array(

                    'player'=>array(self::BELONGS_TO, 'User', 'userId'),

		);

	}


	/**

	 * @return array customized attribute labels (name=>label)

	 */

	public function attributeLabels()

	{

		return array(

			'id' => 'ID',

			'userId' => 'User',

			'gameId' => 'Game',

			'number' => 'Number',

			'megaball' => 'Megaball',

		);

	}


	/**

	 * Retrieves a list of models based on the current search/filter conditions.

	 * @return CActiveDataProvider the data provider that can return the models based on the search/filter conditions.

	 */

	public function search()

	{

		// Warning: Please modify the following code to remove attributes that

		// should not be searched.


		$criteria=new CDbCriteria;


		$criteria->compare('id',$this->id);

		$criteria->compare('userId',$this->userId);

		$criteria->compare('gameId',$this->gameId);

		$criteria->compare('number',$this->number,true);

		$criteria->compare('megaball',$this->megaball);


		return new CActiveDataProvider($this, array(

			'criteria'=>$criteria,

		));

	}

        //serialize the data before save to database

        public function beforeSave()

        {

            $this->number= serialize($this->number);

            return parent::beforeSave();

        }

        //transform the serialized data back into its normal form after find

        public function afterFind()

        {

            $this->number= unserialize($this->number);

            return parent::afterFind();

        }

        public function numberCount($attribute)

        {

            if (count($attribute) != 5)

            {

                $this->addError($attribute, 'you did not select enough numbers!');

            }

              

            

        }

}

i want the numberCount function to validate if there are 5 array elements in my number attribute if not generate an error. Looks like its serialized before its validated. What can i do?
