yii database query inside loop - loops

Question

I didn't get the correct filter out for the following action. Here $val is an array of checked values. But the query executes only for the last element of the array even though I used the foreach loop. Please, can anyone help me?
if( isset($_POST['state']) && count($_POST['state']) > 0 ){
foreach($_POST['state'] as $row => $val ){
$criteria = new CDbCriteria;
$criteria->select='*';
$criteria->condition='pjt_user_id=:pjt_user_id && pjt_pdt_status=:pjt_pdt_status';
$criteria->params=array(':pjt_user_id'=> $user_id, ':pjt_pdt_status'=> $val);
$criteria -> order = 'pjt_id';
$projects= ProjectModel::model() -> findAll($criteria);
}
$this->render('index', array('projects'=>$projects));

Thanks Martin Komara....
I got the solution ...
I just use OR condition in SQL.
if(isset($_POST['state']) && count($_POST['state']) > 0 ){
$i = 0;
foreach($_POST['state'] as $data){
$condit[":$data"] = $data;
if($i!=0){
$var .= ' || ';
}
$var .= " pjt_pdt_status=:$data";
$i++;
}
$var = ' AND (' .$var.' )';
}
$criteria = new CDbCriteria;
$criteria->select='*';
$criteria->condition='pjt_user_id=:pjt_user_id' .$var ;
$criteria->params=$condit;
$criteria -> order = 'pjt_id';
$projects= ProjectModel::model() -> findAll($criteria);

This would be better - much more readable:
if (isset($_POST['state']) && count($_POST['state']) > 0 ) {
$criteria = new CDbCriteria;
$criteria->addInCondition('pjt_pdt_status', $_POST['state']);
$criteria->addColumnCondition(array('pjt_user_id' => $user_id));
$criteria->order = 'pjt_id';
$projects = ProjectModel::model()->findAll($criteria);
}
