将值从JQuery .post传递给PHP

Question

I just started picking up JQuery today, and for some reason I can't get this simple $.post to work when a form is submitted.

I want to pass the value of 2 as star to my PHP page "update_item.php".

I added an alert and saw that when I clicked submit it would give me the alert, but for some reason the value of 2 just doesn't pass to the php page.

Here's what I have with JQuery:

$('#form_edit_item').submit(

    function(){     
        alert("submitting");     
        $.post(
        "edititem.php",
            {star: "2"}, 
        );
    }); 

Here's what I have in update_item.php:

$star = $_POST['star'];
echo "Star value: " .$star. "";

What am I doing wrong? Your help would be very much appreciated! Thanks!

$.post(url, data, callback, "json");
