TalkPHP - Jquery ajax forms in PHP MVC app

I was wondering about this since I am very new to javascript and Jquery in general.

My app uses the MVC approach. Using the ajax. method for submitting a form in Jquery means I need to make the request to a php page. I have tried sending it to site.com/mycontroller/mymethod but it always fails.

If I send it over to a seperate PHP page outside of the MVC app however, it works. Strangely though, even if that page does nothing but return false it still says it works.

Maybe I am not doing this right, but here is the jquery...

Code:

$(document).ready(function(){



        // Hide status message by default

        $(".error").hide();

        $("#error").hide();

        $("#success").hide();



        // Create content

        $("#submit").click(function(){                

        

                // Hide status message by default

                //$("#error").hide();

                //$("#success").hide();

                

                var hasError = false;

                

                // Check that we have a title

                var title = $("#title").val();

                if(title == '') {

                        $("#title_error").show();

                        hasError = true;

                }        

                // Check that we have a url

                var url = $("#url").val();

                if(url == '') {

                        $("#url_error").show();

                        hasError = true;

                }        

                // Check that the full story and short story was not left blank

                var short = $('#short').val();

                var full = $('#full').val();

                if(short == '' && full == '') {

                        $("#short_error").show();

                        $("#full_error").show();

                        hasError = true;

                }        

                // Get form data

                var formData = $('#create_form').serialize(); 

                

                // Check that we dont have errors

                if(hasError == false) {

                        $(this).hide();

                        

                        $.ajax({

                                type: "POST",

                                url: "http://localhost/framework2/public/js/ajax/php/content_create.php",

                                data: formData,

                                cache: false,

                                success: function(){

                                        $('#success').fadeIn("slow");

                                },

                                error: function() {

                                        $('#error').fadeIn("slow");

                                }

                        });

                }

                else {

                        $('#error').fadeIn("slow");

                        $(this).show();

                }

                return false;

        });                                                   

});

Anyone here help with this? I followed a mixture of tutorials to learn how to do this, but honestly most of this was thrown together without the tutorial (all the error checking stuff mostly).

Am I missing anything here? Shouldn't returning false trigger the error option in Jquery? Also, is it possible to send the request to a method in my MVC app? I would much prefer to keep this in the APP so I don't have to get a new instance of the database and have access to all my helpers.
