create $output as a regular array and use the native json_encode function.
return $this->renderText(json_encode($output));
That way you can have something like this in your actions...
if ($request->isXmlHttpRequest())
{
return $this->renderText(json_encode($output));
} else {
return sfView::SUCCESS;
}
Which makes debugging a LOT easier ;)
Having said that, I've never been able to get JSON output to work using headers
only - I've always just sent it as a regular response, without any layout or
template.

Subject: [symfony-users] Problem in sending JSON as AJAX response...???
Hello all,
I am using Symfony 1.2.2 with doctrine plugin and jQuery. I am trying
to create an small application making use of AJAX helper
submit_to_remote(). My response contains JSON format string so I need
to create a callback.
http://www.symfony-project.org/book/1_0/11-Ajax-Integration#chapter_11_json
In this part of documentation I read that the JSON format was being
passed from action directly bypassing the view layer entirely using
the following code
$output = '[["title", "My basic letter"], ["name", "Mr Brown"]]';
$this->getResponse()->setHttpHeader("X-JSON", '('.$output.')');
return sfView::HEADER_ONLY;
I want to send the JSON data using $this->renderText() function...so
will changing the code like this work ???
$output = '[["title", "My basic letter"], ["name", "Mr Brown"]]';
$this->getResponse()->setContentType("text/x-json"); // I am
changing the response header type here
return $this->renderText( $output ); // I am sending the json data
here
This doesn't work for me if I have a callback like this...
function updateJSON(request, json)
{
alert(json); // this displays null
}
Am I setting contentType wrong? or is there something else that I have
goofed up?
thanks and regards
Vikram
