Question

我现在只是想绕着yii框架，我创建了一个删除多个数据库记录的功能。在视图中，我有一个网格，其中包含对每个项目的引用以及旁边的复选框

<?php $this->widget('zii.widgets.grid.CGridView', array(
    'dataProvider'=>$dataProvider,
    'htmlOptions'=>array(
        'class'=>''
    ),
    'columns'=>array(
...
array(
    'class'=>'CLinkColumn',
    'header'=>'Handle',
    'labelExpression'=>'$data->handle',
    'urlExpression'=>'Yii::app()->createUrl(".../item/view", array("id"=>$data->id))',
        ),
array(
    'class'=>'CCheckBoxColumn',
    'header'=>'Select',
    'selectableRows'=>'2',
        ),
    ),

然后在页面的下方我想要一个按钮（删除选中），它将所有项目的数组发送到删除功能。我的想法是类似于这个：

<a href="
<?php echo Yii::app()->createUrl('.../item/bulkDelete','array("id" => $data->id)')?>" 
class="btn">Delete Selected</a>

但我不明白如何获取每个已检查项目的参考，而不是：

"id" => $data->id

因为我以前调用将项目传递给视图函数。如果有人能提供帮助，将不胜感激。

修改

查看：

$form = $this->beginWidget('CActiveForm', array(
        'id' => 'itemForm',
        'action' => array('.../item/bulkDelete'),
        ));

$this->widget('zii.widgets.grid.CGridView', array(
    'dataProvider'=>$dataProvider,
    'htmlOptions'=>array(
        'class'=>''
    ),
array(
    'class'=>'CLinkColumn',
    'header'=>'Handle',
    'labelExpression'=>'$data->handle',
    'urlExpression'=>'Yii::app()->createUrl(".../item/view", array("id"=>$data->id))',
),
array(
    'class'=>'CCheckBoxColumn',
    'header'=>'Select',
    'selectableRows'=>'2',
),
... //More Columns
), //End of Grid
...
echo CHtml::SubmitButton('Delete Multiple');
$this->endWidget();

控制器：

public function actionBulkDelete()
{

    if(isset($_POST['id'])&& !empty($_POST['id'])) 
    { 
        Yii::app()->user->setFlash('success', 'Delete Items');
            $this->redirect(array('.../item/index'));
    } 
    else
    {
        Yii::app()->user->setFlash('success', 'No Items Selected');
            $this->redirect(array('.../item/index'));
    }


}

在表单中包装网格视图，并在columns数组中执行以下更改：

$form = $this->beginWidget('CActiveForm', array(
        'id' => 'some-grid-form',
        'action' => array('myController/myAction'),
));

 $this->widget('zii.widgets.grid.CGridView', array(
    'dataProvider'=>$dataProvider,
    'selectableRows' => 2,
    'columns'=>array(
     array(
            'id' => 'id',
            'class' => 'CCheckBoxColumn',
        ),
    //... rest of your columns
    ),
    array(
        'class'=>'CButtonColumn',
    ),
  ),
));

echo CHtml::SubmitButton('Multiple Delete');
$this->endWidget(); // end form

在你的控制器myAction中：

public function actionmyAction()
    {
        if(isset($_POST['id']) && !empty($_POST['id'])) { //you'll get all the ids in an array
            //print_r($_POST['id']); 
            //your delete function here, also add a few validation here to authenticate deletion
            $ids = $_POST['id'];
            $criteria = new CDbCriteria;
            $criteria->addInCondition('id',$ids);
            MyModel::model()->deleteAll($criteria);
            //.... render with success flash message etc.
        }
    }
