JToolBarHelper::cancel() how to pass parameters?

[Mike]

How can I pass a parameter with joomla's dot notation using JToolBarHelper::cancel()?

In my controller, I'm using a required parameter in the cancel() method.  Here's my code:

public function cancel($groupid)

{

     $app = JFactory::getApplication();

     $link = 'index.php?option=com_mycomponent&view=group&groupid=' . $groupid;

     $app->redirect($link, NULL, NULL, FALSE);

}

In my view.html.php file, I've added:

JToolBarHelper::cancel('item.cancel', 'JTOOLBAR_CANCEL');

How/where can I include the $groupid parameter to cancel()?  Or is there somewhere else I can set the redirect url?

Thanks!

Hi.

You cannot. You should pass it in the hidden field and then retrieve in controller.

Dimitri,

What's the "hidden" field and how do I pass the info?  What does the code look like?

Thanks!

For sure you are using form. When cancel button is clicked, form is submitted. So you can pass input field inside your form like:

<input type="hidden" name="groupid" value="yourgroupid" />

Then retrieve it in controller using JInput.
