how to count $dataProvider items

Question

how can i count data that will retrieved by $dataProvider ? i've tried to use this code,

       $dataProvider = new CActiveDataProvider('Model');
       $dataProvider->totalItemCount;

Answer 1

In yii2

For total count use

$dataProvider->getTotalCount()

For page count then

$dataProvider->getCount()

Refrence page http://www.yiiframework.com/doc-2.0/yii-data-basedataprovider.html#getTotalCount()-detail

Answer 2

I think you have to first fill the dataprovider with data then get the count:

 $dataProvider->getData();
 var_dump($dataProvider->totalItemCount);

or use the function to retrieve directly:

 var_dump($dataProvider->getTotalItemCount());
