I didn’t mentioned that my ajaxable attribute is

public $ajaxable = array(’convert’=>array(’json’));

I've done it like this, but 3 problems occured:

My view script (convert.json.phtml in my case) is not rendered, even if I have:

class AjaxController extends Zend_Controller_Action { public $ajaxable = array('convert'=>array('json'));

public function preDispatch()
{
    $this->_request->setParam('format', 'json');
    $this->_helper->ajaxContext()->initContext();
}

...

}

I cannot acces post data in my controller with:

$this->getRequest('text');

even If $_POST['text'] is set and I can use it.

When I echo something in my ajax controller action, [] is appended to start of my response to the client. Headers are properly set to json.

Hi Sven,

The helper is intended to ensure that you can send back the correct format to the browser.

For the second point: I didn't handle html escaping properly here in the post whilst implementing the syntax highlighting. Should be fixed now.

Regards,

Rob..

A couple of questions:

If "This action is already "ajaxed"" then why do you need to use this ajax helper?
In the array you set up for $ajaxable why does feedback = &gt?

Can you put the code to download ? It could be nice so we can learn more about this interested helper.

One note — you don’t have to setup the helper in your bootstrap; helpers such as this one can be loaded on-demand in your controllers simply by invoking them: $this->_helper->ajaxContext->initContext().
