过滤器在Yii CGridView中不起作用

Question

I am new to Yii. I am displaying some data in my view. I have added filters in my View, But it seems not working. Please help me solving this.

My View:

<?php
/* @var $this NimsoftHostsDetailsController */
/* @var $model NimsoftHostsDetails */
$this->breadcrumbs=array(
    'Nimsoft Hosts Details'=>array('index'),
    $model->id,
);

$this->menu=array(
    array('label'=>'List NimsoftHostsDetails', 'url'=>array('index')),
    array('label'=>'Create NimsoftHostsDetails', 'url'=>array('create')),
    array('label'=>'Update NimsoftHostsDetails', 'url'=>array('update', 'id'=>$model->id)),
    array('label'=>'Delete NimsoftHostsDetails', 'url'=>'#', 'linkOptions'=>array('submit'=>array('delete','id'=>$model->id),'confirm'=>'Are you sure you want to delete this item?')),
    array('label'=>'Manage NimsoftHostsDetails', 'url'=>array('admin')),
);
?>

<h1>View NimsoftHostsDetails - </h1><h3><?php echo "Host Name - ".$host_name;?></h3>
<?php 
      if(Yii::app()->user->hasFlash('error'))
        {

?>

My view displays data, but in filtering part, If I input any text, its does not return anything. Please help me. Thanks in advance.

Answer 1

make sure that the values you are using in your filter goes inside your model

public function search()
     {
    // @todo Please modify the following code to remove attributes that should not be searched.

    $criteria=new CDbCriteria;

    $criteria->compare('id',$this->id);
    $criteria->compare('host_id',$this->host_id);
    $criteria->compare('host_start_date',$this->host_start_date,true);
    $criteria->compare('host_end_date',$this->host_end_date,true);

    return new CActiveDataProvider($this, array(
        'criteria'=>$criteria,
    ));
}

i'm having a hard time to read your code. So what field did you add to use as filter? is it by default included in your model?
