Yii Framework - Using CCheckBoxColumn to delete multiple - php

Question

I'm just trying to wrap my head around the yii framework at the moment and I've created a function to delete multiple database records at once. In the view I've got a grid with a reference to each item and a checkbox next to it
<?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',
),
),
Then further down the page I want a button (delete selected) which sends an array of all of the items to a delete function. My thoughts were it would be something akin to this:
<a href="
<?php echo Yii::app()->createUrl('.../item/bulkDelete','array("id" => $data->id)')?>"
class="btn">Delete Selected</a>
But I don't understand how to get a reference for each checked item instead of :
"id" => $data->id
as I used to call pass an item to the view function earlier. If anyone can help it will be greatly appreciated.
Edit:
View:
$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');
$this->endWidget();
Controller:
public function actionBulkDelete()
{
if(isset($_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'));
}
}

Wrap the grid view inside a form, and do the following changes in your columns array:
$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');
$this->endWidget(); // end form
And in your Controller's myAction:
public function actionmyAction()
{
if(isset($_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.
}
}
