Yii 批量删除

1.首先，写button按钮：

视图中，columns下面声明checkbox代码：

array(
'class' => 'CCheckBoxColumn',
'selectableRows' => 2,
'footer' => '<button type="button" onclick="GetCheckbox();" style="width:76px">批量删除</button>',
'checkBoxHtmlOptions' => array('name' => 'id[]'), //name在js中会用到
),

例子如下：

<?php $this->widget('admin.widgets.GridView', array(

'id'=>'app-comment-grid',

'dataProvider'=>$model->search(),

'filter'=>$model,

'columns'=>array(

array(

'selectableRows' => 2,

'footer' => '<button type="button" onclick="GetCheckbox();" style="width:72px">批量删除</button>',

'class' => 'CCheckBoxColumn',

'headerHtmlOptions' => array('width'=>'33px'),

'checkBoxHtmlOptions' => array('name' => 'selectdel[]'),

),

array(

'header'=>'App图标',

'type'=>'raw',

'value'=>'CHtml::link(CHtml::image($data->app->getIcon57x57()), $data->app->getQianUrl(),array("target"=>"_blank"))',

'htmlOptions'=>array(

'width'=>'57',

'height'=>'57',

'style'=>'text-align:center',

),

array(

'header'=>'操作',

'class'=>'CButtonColumn',

'headerHtmlOptions'=>array(

'width'=>'40',

),

'template'=>'{update}{delete}', //默认显示的三个按钮，要去掉某个按钮，删除相应项即可

),

),

)); ?>

<script type="text/javascript">

/*<![CDATA[*/

var GetCheckbox = function (){

var data=new Array();

$("input:checkbox[name='selectdel[]']").each(function (){

if($(this).is(":checked")){

data.push($(this).val());

}

});

if(data.length > 0){

if(confirm('确定要删除选中的留言吗？')){

$.post('<?php echo CHtml::normalizeUrl(array('/admin/appComment/delall/'));?>',{'selectdel[]':data}, function (data) {

var ret = $.parseJSON(data);

if (ret != null && ret.success != null && ret.success) {

$.fn.yiiGridView.update('app-comment-grid');

}

});

}else

return false;

}else{

alert("请选择要删除的留言!");

}

}

/*]]>*/

</script>

2.js中post请求的控制器中写逻辑代码：

public
function actionDelall()
{

if
(Yii::app()->request->isPostRequest)
{

$criteria
=
new
CDbCriteria;

$criteria->addInCondition('id',
$_POST['id']);

News::model()->deleteAll($criteria);
//News换成你的模型

if
(isset(Yii::app()->request->isAjaxRequest))
{

echo CJSON::encode(array('success'
=>
true));

}
else

$this->redirect(isset($_POST['returnUrl'])
? $_POST['returnUrl']
: array('index'));

}

else

throw
new
CHttpException(400,
'Invalid request. Please do not repeat this request again.');

}
