Ajax script not working - php

Question

I know I should be more specific about the problem but I don't know what it is but once I have an answer I fix the post.
Here is the problem simple ajax script but somehow it isn't working. I can't see any error on the code =/
jQuery part:
$(document).ready(function()
{
var addFavPhp = '../functions/addfav.php';
var orange = 'orange';
var favLinkError = false;
var favNameError = false;
$('#addFavButton').click(function()
{
var favLink = $('.favLinkInput').val();
var favName = $('.favNameInput').val();
var fileName = $('.file').val();
if(favLink=="")
{
$('.favLinkInput').css('border-color',orange);
favLinkError = true;
}
if(favName=="")
{
$('.favNameInput').css('border-color',orange);
favNameError = true;
}
if((favLinkError==false) && (favNameError==false))
{
$.post(addFavPhp,{favLink:favLink,favName:favName,fileName:fileName},function(addFav)
{
$('.favLinkInput,.favNameInput').val('').css('border-color','');
$('.file option[value=""]').attr("selected", "selected");
location.reload();
});
}
});
});
and php part:
<?php session_start();
include('../functions/connect.php');
if(!empty($_SESSION['username']))
{
$username = $_SESSION['username'];
}else
if(!empty($_COOKIE['PHPCOOKID']))
{
$cookie = htmlspecialchars(trim($_COOKIE['PHPCOOKID']));
$explode = explode('-', $cookie);
$username = $explode['0'];
}
$favLink = htmlspecialchars(trim($_POST['favLink']));
$favName = htmlspecialchars(trim($_POST['favName']));
$fileName = htmlspecialchars(trim($_POST['fileName']));
$d = array($username,$favLink,$favName,$fileName);
$req = $DB->prepare('INSERT INTO favs (username,favLink,favName,favFile) VALUE (? , ? , ? , ?)');
$req->execute($d);
?>
What I figure out is that it stop working around $.post but I can't figure out why. And it works find on local server.
Thanks for any help.

looks like the line var addFavPhp = '../functions/addfav.php'; is wrong. you have to use http urls when doing ajax. somthing like /path/to/addfav.php
