Hi Guys,
I'm trying to build an ajax application and am running into troubles
with ESI. Here's a simple version of what I'm trying to do:
4 content areas:
- Header
- Footer
- Sidebar
- Content
When a link is clicked, an ajax request is fired that gets the content
and updates the relevant page areas.
In my controller:
// If it's an ajax request, return a JSON structure with the seperate
page parts to update.
if ($request->isXmlHttpRequest())
{
$result = array();
$result['title'] = $title;
$result['page_header'] = $templating-
>render('LimelightBundle:Core:home_header.html.twig');
$result['page_content'] = $templating-
>render('LimelightBundle:Core:home_content.html.twig');
$response = new Response(json_encode($result));
$response->headers->set('Content-Type', 'application/
json');
return $response;
}
// Else it's a normal request, return the full response.
return $this->container->get('templating')-
>renderResponse('LimelightBundle:Core:home.html.twig', array('title'
=> $title), $response);
As you can see, I'm trying to return a JSON object with the relevant
properties filled with the relevant page sections. Now, in the
home_content.html.twig template I call a few ESI tags. They work fine
on a regular page load, but do not work when I try to use the method
above to return parts of the page via JSON.
It simply returns the json structure with the <esi src="" /> tags
without replacing the ESI tags with their actual content.
Any thoughts on how to fix this or the best way to go about doing
this? If anyone needs any clarification please let me know.
Thanks!
Marc
