    {
        $criteria = new CDbCriteria();
        $criteria->params=(array(':account_type'=>'credit'));
        $dataProvider=new CActiveDataProvider('Payments');
    $this->render('index',array(
        'dataProvider'=>$dataProvider,
    )); 
    }

I want to display all the rows in payment page those which are given credit. I'am a beginner to yii. can anyone please help me to solve my problem? This is my view file.

Answer 1

try this:

public function actionPayment()
{
    $criteria = new CDbCriteria();
    $criteria->condition = "account_type = :account_type";
    $criteria->params=(array(':account_type'=>'credit'));
    $dataProvider=new CActiveDataProvider('Payments',array(
        'criteria'=>$criteria,
    ));
    $this->render('index',array(
        'dataProvider'=>$dataProvider,
    )); 
}

Answer 2

You can also use this

$criteria->compare('account_type', 'credit');

Against

$criteria->condition = "account_type = :account_type";
$criteria->params=(array(':account_type'=>'credit'));

Full example:

criteria = new CDbCriteria();
$criteria->compare('account_type', 'credit');
$dataProvider=new CActiveDataProvider('Payments',array(
    'criteria'=>$criteria,
));
