I have a fairly complex bit of data I'd like to pass over as a session variable. Ideally, I'd pass an array. When I do that, the FC.json.custom_fields gives me a value of 1 for that session variable.
http_build_query(array("h:addon" => $addon));
$addon is a decent sized array of data.
Do I need to think of a different way to do this? An ajax request back to my server?
