Submit CGridView Checked Values ​​Using Form

I have a CigridView wigdet with CCheckBoxColumn like this:

$this->widget('zii.widgets.grid.CGridView', array(
    'dataProvider'=>$dataProvider,
    'columns'=>array(
        array(
            'class'=>'CCheckBoxColumn',
        ),
        'title',
        ....
    ),
));

Question: how to feed validated values ​​to the controller action? I understand that I need a form, a submit button, but I need a clear explanation of where to put things so that the search boxes are displayed on top.

Thanks in advance.

You don't need a completely different shape. You can just use the link with additional javascript attached to it.

To get checked values, you can call javascript function $.fn.yiiGridView.getChecked(containerID,columnID)

, see here , it returns an array containing ids.

Complete example (with ajax):

In your opinion:

<?php
$this->widget('zii.widgets.grid.CGridView', array(
   'id'=>'example-grid-view-id', // the containerID for getChecked
   'dataProvider'=>$dataProvider,
   'columns'=>array(
       array(
           'class'=>'CCheckBoxColumn',
           'id'=>'example-check-boxes' // the columnID for getChecked
       ),
       'title',
       ....
   ),
));
?>
<div id="for-link">
<?php
   echo CHtml::ajaxLink('SomeLink',Yii::app->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
        )
   );
?>
<div>


In your controller:

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

You can also use a json string instead of a simple string in the data we ajax pass (from the view), but explode()

you have to use json_decode()

(in the controller) instead . It would also be better to check / sanitize IDs before use.

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

Note that the example is a bit rough, as I did not put checks on an empty array of checked ids.

This works with CSRF protection and updates the GridView.



<?php
echo CHtml::ajaxLink('ClickMe',Yii::app()->createUrl('controller/action'),
array(
'type'=>'POST',
'data'=>'js:{"ids" : $.fn.yiiGridView.getChecked("grid_view_id","check_box_id").toString(),"YII_CSRF_TOKEN" : "'.Yii::app()->request->csrfToken.'"}',
'success'=>"$('#grid_view_id').yiiGridView.update('grid_view_id')"
));
?>

If you wrap the Gridview in a simple form, you can submit the checkboxes selected to value,

Example:

View

<form id="frmSubmit">
<?php
echo CHtml::dropDownList('user_id'
        , null
        , CHtml::listData(User::model()->findAll(), 'USER_ID', 'FULLNAME')
);

echo CHtml::ajaxSubmitButton('Save'
                            , Yii::app()->createUrl('query/ajaxUpdate')
                            , array('success' => 'js:reloadGrid', )
                            , array('class' => 'btn btn-success'));

$this->widget('zii.widgets.grid.CGridView', array(
    'id'=>'query-grid',
    'dataProvider'=>$model->search(),
    'filter'=>$model,
    'columns'=>array(
        array(
            'id' => 'query',
            'class'=>'CCheckBoxColumn',
            'selectableRows' => '2',
        ),
        'Contact',
        'Email',
        'Company',
    ),
)); ?>
</form>

<script type="text/javascript">
function reloadGrid(data) {
    $.fn.yiiGridView.update('query-grid');
}
</script>

controller

public function actionAjaxUpdate()
{
    var_dump($_POST);
}
