本文介绍如何在Yii框架中实现GridView分页大小的自定义设置。通过修改控制器、模型及视图文件，可以为用户提供一个下拉框选择不同的页面大小，并将选择保存在用户状态中。

A convenient drop down to select page size and save in User state.

Step 1: On top of my controller action for the gridview (if you used CRUD, this isactionAdmin() ) i added:

 
// page size drop down changed
 
if (isset($_GET['pageSize'])) {
 
    Yii::app()->user->setState('pageSize',(int)$_GET['pageSize']);
 
    unset($_GET['pageSize']);  // would interfere with pager and repetitive page size change
 
}

Step2: In the model (e.g. model/User.php) the data provider in search() is configured like:

 
return new CActiveDataProvider(get_class($this),array(
 
    'pagination'=>array(
 
        'pageSize'=> Yii::app()->user->getState('pageSize',Yii::app()->params['defaultPageSize']),
 
    ),
 
    'criteria'=>$criteria,
 
));

Step 3: Now the view (e.g. views/user/admin.php) :

 
<?php
 
// put this somewhere on top
 
$pageSize=Yii::app()->user->getState('pageSize',Yii::app()->params['defaultPageSize']); ?>
 
 
 
<?php
 
// we use header of button column for the drop down
 
// so change the CButtonColumn in columns array like this:
 
...
 
array(
 
    'class'=>'CButtonColumn',
 
    'header'=>CHtml::dropDownList('pageSize',$pageSize,array(20=>20,50=>50,100=>100),array(
 
        // change 'user-grid' to the actual id of your grid!!
 
        'onchange'=>"$.fn.yiiGridView.update('user-grid',{ data:{pageSize: $(this).val() }})",
 
    )),
 
),

Step 4: And finally the application parameter

 
// Accessable with Yii::app()->params['paramName']
 
'params'=>array (
 
 
 
    'defaultPageSize'=>20,
