php - How to set multiple condition on criteria for CActiveDataProvider?

Question

I'm on project of YII. I have Production table, where I have category_id and brand_id two column. Now what I want to do is, just use the CActiveDataProvider to fetch those particular rows to the $dataprovider which has those category_id and brand_id in my $cat and $brnd array. I made it for category_id, but I am not getting any thing how to put both of them on the condition. Here is my code, please help.

$dataProvider=new CActiveDataProvider(Production::model(),
      array(
     'criteria'=>array('condition' => 'category_id IN ('.implode(',',$cat).')'),
     'pagination' => array('pageSize'=>Yii::app()->params['productsPerPage']),
    )
);

Answer 1

Use addInCondition of CDbCriteria:

$criteria=new CDbCriteria;
$criteria->addInCondition('category_id',$cat,'AND');
$criteria->addInCondition('brand_id',$brnd,'AND');
$dataProvider=new CActiveDataProvider(
    'Production',
    array(
        'criteria'=>$criteria,
        'pagination' => array('pageSize'=>Yii::app()->params['productsPerPage']),
    )
);

The last parameter of addInCondition specifies how the condition will be appended to the existing conditions, so if you want

category_id IN (x,y,z) AND brand_id IN (a,b,c)

i.e AND then you don't need to specify the 3rd parameter (default is AND), but if you want OR, as in

category_id IN (x,y,z) OR brand_id IN (a,b,c)

then you need to use

$criteria->addInCondition('brand_id',$brnd,'OR');
