Yii CGridview没有过滤

Question

I'm trying to work with a YII CGridview to display some data.

This is home my model search function looks like:

/**
 * Retrieves a list of models based on the current search/filter conditions.
 * @return CActiveDataProvider the data provider that can return the models based on the search/filter conditions.
 */
public function search()
{
    $criteria=new CDbCriteria;
    $criteria->compare('ip',$this->ip,true);
    $criteria->compare('first_use',$this->first_use,true);
    $criteria->compare('last_use',$this->last_use);
    $criteria->compare('memberid',$this->memberid);
    $criteria->compare('countryid',$this->countryid);
 
    return new CActiveDataProvider(get_class($this), array(
        'criteria'=>$criteria,
));
}

And this is how my view looks like

$this->widget('zii.widgets.grid.CGridView', array(
        'id'=>'iplog-grid',
        'dataProvider'=>$oIPLog->search(),
        'filter'=>$oIPLog,
        'summaryText' => 'showing you {start} - {end} of {count} logged Ips',
        'columns'=>array(
            array(
                'name'=>'ip',
                'type'=>'raw',
),
            array(
                'name'=>'first_use',
                'type'=>'datetime',
),
            array(
                'name'=>'last_use',
                'type'=>'datetime',
),
),
));

Displaying the CGridview works, but I can't seem to get the filter on top of it to work. It sends the call and I don't get any error as reponse, it just returns the whole unfiltered data again..

Any clues?

Answer 1

And how exactly does your controller look like?

For the CGridview filter to work you need to check in your controller if there are any filters set and then return the filtered object.

To clarify, something like this should be placed into your controller action

$oObject = new Object('search');
if (isset($_GET['Object'])) {
    $oObject->attributes = $_GET['Object'];
}

Hope this helps
