Hello.
I'm trying to create a custom widget [1]. This "widget" is actually a
mini-form with his own submit button, which posts to its own
controller method. I configure it in the form::configure as:
'app_icon' => new
WidgetFormInputAjaxUpload(array('post_url' =>
url_for('apps/upload').'?id='.$this->getObject()->getId()))
Now, I need the "widget" to know the csrf token, so that I can
validate it in the upload action. But, I don't know how to get to the
csrf token when I'm building the form, to set it on the widget. How
can I obtain it?
(In essence, I need to be able to pass the "app[_csrs_token]" and the
token value to some methods during the form::configure, but I don't
know how to access either the 'app[_csrs_token]' string, nor the token
itself. If I just hardcode those strings in the widget, it works.)
Regards,
Luis.
[1] the widget is based on the AJAUpload solution presented in
http://valums.com/ajax-upload/. The idea is to be able to change an
icon without having to submit the whole form, so that the user can
upload and see previews of his upload before sending the whole form.
