YII CGridView的分析

<?php 
	$this->widget('zii.widgets.grid.CGridView', array(
    'dataProvider'=>$dataProvider,
    'pager'=>Yii::app()->params['pager'],     //定义在配置文件params.php里面
    'ajaxUpdate'=>false,
    'columns'=>array(
    	array(
    		'class'=>'CCheckBoxColumn',
    		'value'=>'$data->id',   //注意这里用的是$data
    		'htmlOptions'=>array(
    			'width'=>'5px',
    		),
    	),
    	array(
    		'name'=>'序号',
    		'value'=>'$row+1',         //序号$row+1;
    		'htmlOptions'=>array(
    			'width'=>'5px',
    		),
    	),
    	'title',                              //如无属性可直接写一个属性；可直接在数据库取得数据
    	array(
    		'name'=>'cid',
    		'value'=>'$data->category->title',
    		'htmlOptions'=>array(
    			'width'=>'80px',

    	array(
    		'class'=>'CButtonColumn',
    		'header'=>'缩略图',
    		'buttons'=>array(                                       //自定义按钮
    			'preview'=>array(    
    				'url'=>'',    //可以加createUrl链接 不能www
    				'imageUrl'=>BASEURL.'/resources/icons/picture.png',   //图标图片
    				'visible'=>'Yii::app()->controller->girdShowImg($data);',  //积累控制器方式，如果有缩略图就可见
    			),
    		),
    		'template'=>'{preview}',     //自定义一定要加上这句话
    	),
    	array(
    		'name'=>'hits',
    		'value'=>'$data->hits',
    		'htmlOptions'=>array(
    			'width'=>'40px',
    			'align'=>'center',

    		'value'=>'date("Y-m-d",$data->create_time)',
    		'htmlOptions'=>array(
    			'width'=>'70px',
    			'align'=>'center',
    		),
    		'visible'=>'false',
    	),
    	array(
    		'name'=>'update_time',
    		'value'=>'date("Y-m-d",$data->update_time)',
    		'htmlOptions'=>array(
    			'width'=>'70px',
    			'align'=>'center',
    		),
    		'visible'=>'false',
    	),

			"id"=>"$data->id","menupanel"=>"$_GET[menupanel]","cid"=>"$_GET[cid]","title"=>"$_GET[title]"))',//编辑 ，然后ajax删除。
    	),
    	
    ),
));
 ?>

基类控制器Controller代码：

	public function actionDelete($id)  //
	{
		if(Yii::app()->request->isPostRequest)
		{
			// we only allow deletion via POST request
			if($this->loadModel($id)->delete()){
				Yii::app()->user->setFlash('actionInfo',Yii::app()->params['actionInfo']['deleteSuccess']);
			}else {
				Yii::app()->user->setFlash('actionInfo',Yii::app()->params['actionInfo']['deleteFail']);
			}
			// if AJAX request (triggered by deletion via admin grid view), we should not redirect the browser
			if(!isset($_GET['ajax']))
				$this->redirect($_POST['returnUrl']);  
		}
		else
			throw new CHttpException(400,'Invalid request. Please do not repeat this request again.');
	}


	protected function girdShowImg($data)
	{
		if(!empty($data->imgurl))
			return true;
		else
			return false;
	}

	protected function showViewUrl($type,$data){
		return str_replace('admin.php','index.php',Yii::app()->createUrl("$type/view",array('id'=>$data->id))); //因为这是在admin环境下
	}

　　

扩展：

批量删除的使用：

array(
                            'selectableRows' => 2,
                            
                            'footer' => '<button type="button" onclick="GetCheckbox();" style="76px">批量删除</button>',
                            'class' => 'CCheckBoxColumn',
                            'headerHtmlOptions' => array('width'=>'1px'),
                            'checkBoxHtmlOptions' => array('name' => 'selectdel[]'),
                    ),

　　

 <script type="text/javascript">
    /*<![CDATA[*/
    var GetCheckbox = function (){
	         if (confirm("确定要删除此系别吗 ?")){
            var data=new Array();
            $("input:checkbox[name='selectdel[]']").each(function (){
                    if($(this).attr("checked")==true){
                            data.push($(this).val());
                    }
            });
            if(data.length > 0){
                    $.post('<?php echo CHtml::normalizeUrl(array('/article/delall/'));?>',
					{'selectdel[]':data}, 
					function (data) {
                          var ret = $.parseJSON(data);
                           if (ret != null && ret.success != null && ret.success) {

            }else{
                    alert("请选择要删除的关键字!");
            }
    }
	}
    /*]]>*/
    </script>

　　

ublic function actionDelall()
            {
                    if (Yii::app()->request->isPostRequest)
