Symfony2 Form with CSRF passed through JQuery AJAX
Try with the adequate JQuery function: submit() ^^ In my solution I suppose that your form has the id "comment_form". Works on all my sf2 projects:
$('#comment_form').submit(function(e) { var url = $(this).attr("action"); $.ajax({ type: "POST", url: url, // Or your url generator like Routing.generate('discussion_create') data: $(this).serialize(), dataType: "html", success: function(msg){ alert("Success!"); } }); return false;});The CSRF Field would normally be sent !
And don't forget to add the twig tag {{ form_rest(form) }} in your form template, that will generate all hidden field like CSRF.
