Question

I am developing a comments box that will save the comment through a JQuery AJAX call.

JQuery

Here\'s the JQuery code for that (this works seamle

Answer 1

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.
