yii1的后台分页和列表

控制器：

public function actionIndex()
{
    $model = new Cases('search');
    $model->unsetAttributes(); // clear any default values
    if (isset($_GET['Cases'])) $model->attributes = $_GET['Cases'];
    $this->render('index', ['model' => $model]);
}

model：

public function rules()
{
    return array(
        array('title', 'required'),
        array('course_type', 'safe'),
        // The following rule is used by search().
        array('title', 'safe', 'on' => 'search'), //这个是用来搜索用的
    );
}

public function search($act='')
{
    $criteria=new CDbCriteria;
    $criteria->compare('id',$this->id);
    $criteria->compare('title',$this->title,true);
    $criteria->compare('time',$this->time,true);
    $criteria->compare('course_type',$this->course_type,true);

    if($act == 'list') $this->status = 1;
    if($act == 'recycle') $this->status = 0;
    $criteria->compare('status',$this->status);

    $criteria->order = ' id DESC ';
    return new CActiveDataProvider($this, array(
        'criteria'=>$criteria,
    ));
}

视图：

<div class="tab-pane active" id="list">
    <?php
    $this->widget ( 'zii.widgets.grid.CGridView', array (
        'id' => 'users-grid-list',
        'dataProvider' => $model->search('list'),
        'filter' => $model,
        'columns' => array (
            'title',
            array (
                'name' => 'course_type',
                'value' => array (
                    $this,
                    'getCourse'
                ),
                'filter' => $course_list
            ),
        )
    ) );
    ?>
</div>
