**Example 9: Linking to a controller action via POST with confirmation dialog**

Delete actions created using gii require the delete request be sent via POST to help prevent deleting objects by accident. Below is an example how to create a link that sends the request via POST and also asks for confirmation. Where you are redirected after the delete depends on your delete action.
 
 
```php 
<?php echo CHtml::link('Delete',"#", array("submit"=>array('delete', 'id'=>$data->ID), 'confirm' => 'Are you sure?')); ?Note that the `id` link parameter below is a GET type parameter (submit URL will be something like `http://example.com/post/delete/id/100`).
 
 
```php 
<?php echo CHtml::link('Delete',"#", array("submit"=>array('delete', 'id'=>$data->ID), 'confirm' => 'Are you sure?')); ?>
 
```
 
If you are using CSRF protection in your application do not forget to add csrf parameter to the htmlOptions array.
 
 
```php 
<?php echo CHtml::link('Delete',"#", array("submit"=>array('delete', 'id'=>$data->ID), 'confirm' => 'Are you sure?', 'csrf'=>true)); ?>
 
```

**Example 10: Linking to a controller action via POST with POST parameters**
 
 
If you need to make POST request with arbitary link with additional POST parameters you should use following code (submit URL will be something like `http://example.com/blog/deletePost/param/100`).
 
 
 
```php 
<p><?php echo lnk('Delete blog post', '#', array(
 
'submit'=>array('blog/deletePost', 'param'=>100),
 
'params'=>array('id'=>$post->id, 'status'=>Post::STATUS_DELETED_BY_OWNER),
 
'csrf'=>true,
 
)); ?></p>
```

```
