Disable Smarty on a single page in ActiveCollab

I'm working on a system (ActiveCollab) that uses Smarty for templates. I want to output some JSON so I need to have it output by itself... no other cruft. However, if I do NOT provide a Smarty template file for the corresponding action I get an error output that ruins the JSON.

Does anyone know how to disable Smarty output on a case by case basis? In pseudocode, something like 

$this->smarty->disable();

Failing that, does anyone know how to have ActiveCollab not require a template file for output? Or even know of a better way to output JSON for consumption within ActiveCollab?

My main goal is to output json for use by jqgrid within ActiveCollab, in case that helps.

Thanks.

EDIT:

It turns out it's as simple as adding die(); after the desired output.

function bar(){
    echo $myoutput;
    die();
}

That's it. Why I always look for the "hard" answer when the solution is so basic I will never know... sigh.

Solution

  • activeCollab will automatically render page layout around page content only if action itself did not provide an exit before it ended execution. This exit may be:

    1. Serving some data with $this->serveData()
    2. Page redirection
    3. Simple printing of content + die()
    4. File forward, using download_file() and download_content() function
    5. Any other exist that stops execution of action (dies within it)

    In your case, you can use controller's serveData() method to serve JSON:

    function action() {
  $my_json_data = array('something');

  $this->serveData($my_json_data, null, FORMAT_JSON);
}

    This function will set proper HTTP headers and encode the value that you are sending.
