Question

我正在使用Yii，如果我点击更新图标，在CGridView中，id=之后没有任何内容（以quwey字符串形式）

URL?r=employes/update&id=

查看

<?php
 $this->widget('zii.widgets.grid.CGridView', array( 
 'id'=>'employee-grid',
 'dataProvider'=>$model->EmpList(),
 'columns'=>array(
  'employee_no', 
    ....
  'date_created',
  array(        
   'class'=>'CButtonColumn',
    'template'=>'{update} {delete}',
  ),            
 ),     ));
?>

有什么问题？

 public function actionIndex()
        {
                // here is your code for this action
                $model = new Emp;
                //              print_r ($_POST);
                if(isset($_POST['Emp'])) {

您没有将id值传递给网格中的更新按钮。如下所示更改您的网格视图：

......
......
'template'=>'{update} {delete}',
'buttons'=>array
        (
         'update'=>array
            (
                'url'=>'Yii::app()->createUrl("employes/update",$params=array("id"=>$data->emp_id))',
            ),
          'delete'=>array
          (
            'url'=>'Yii::app()->createUrl("employes/delete",$params=array("id"=>$data->emp_id))',
          )   
        )
......
