How to convert this code to fit in Yii

Hi, All any help asap will be highly appreciated.

here my issue is converting this code to yii way especially the mysql_num_rows

public function votedBefore($item_id){

    $ip = $_SERVER['REMOTE_ADDR'];

    $query = "SELECT * FROM {{item_votes}} WHERE ip = '$ip' AND classified = '$item_id'";

    $result = mysql_query($query);

    if(mysql_num_rows($result)>0){ // already voted

    return true;

    } elseif(mysql_num_rows($result)==0){ // haven't voted

    return false;




How can this be converted to yii way again - mysql_fetch_assoc.

public function countUpVotes($item_id) {

    $query = "SELECT * FROM {{votes}} WHERE item_id= '$item_id' AND `vote_value`>0";

    $result = mysql_query($query);

    $votes = 0;

    while($row = mysql_fetch_assoc($result)){



    return (int) $votes;

First, use MySQL aggregate functions to retrieve data you really need:

SELECT COUNT(*) FROM item_votes WHERE id=...

SELECT SUM(vote_value) FROM votes WHERE item_id=...

then read the DAO section of guide.

Thanks I got it working by doing some research. And here is the final code.

I don’t know if this is ok.

Now i need to get the results via Ajax.

 public function voteUp($vote)


    $ip = $_SERVER['REMOTE_ADDR'];

    $criteria = new CDbCriteria;

    $criteria->condition='itme_id = :itemId AND ip_address = :Ip';

    $criteria->params=array(':itemId'=>$this->id, ':Ip' => $ip);

    $votes =  Votes::model()->count($criteria); 

    if($votes == 0){

    $vote->classified_id = $this->id;

    $vote->ip_address = $ip;



    return false;
