Submit CGridView Checked values using a form

Question

I have a CGridView wigdet with CCheckBoxColumn like this:

$this->widget(\'zii.widgets.grid.CGridView\', array(
    \'dataProvider\'=>$dataProvider,

You do not absolutely need another form. You can just use a link with additional javascript attached to it.

To get the checked values, you can call the javascript function $.fn.yiiGridView.getChecked(containerID,columnID), see here, it returns an array containing the ids.

Full example (with ajax):

In your view:

widget('zii.widgets.grid.CGridView', array(
   'id'=>'example-grid-view-id', // the containerID for getChecked
   'dataProvider'=>$dataProvider,
   'columns'=>array(
       array(
           'class'=>'CCheckBoxColumn',
           'id'=>'example-check-boxes' // the columnID for getChecked
       ),
       'title',
       ....
   ),
));
?>

createUrl('somecontroller/someaction'),
        array(
           'type'=>'POST',
           'data'=>'js:{theIds : $.fn.yiiGridView.getChecked("example-grid-view-id","example-check-boxes").toString()}'
           // pay special attention to how the data is passed here
        )
   );
?>

In your controller:

...
public function actionSomeaction(){
    if(isset($_POST['theIds'])){
          $arra=explode(',', $_POST['theIds']);
          // now do something with the ids in $arra
          ...
    }
    ...
}
...

You could also use json string, instead of simple string, in the data we pass by ajax (from the view), but then instead of explode(), you would use json_decode() (in the controller). Also it would be better to validate/sanitize the ids before use.

Check out the documentation for CHtml::ajaxLink to know more about ajax links.

Note that the example is a little crude, since i haven't put in checks for empty array of checked ids.
