jQuery not sending form correctly

Everytime I submit this form, instead of it POSTing to the server, for some reason it re-loads the page and adds all the data as a GET

I was wondering if anyone see an error in the following code.

$("#updatebusiness").live('click', function(event){

        var tradingname = $('#tradingname').attr('value');
        var website     = $('#website').attr('value');

Have you ever tried using jQuery's build in $.post() method?

you could easily shrink the code down to:

$("#updatebusiness").live('click', function(event){
$.post("system/classes/core.php", $("#your-form-id").serialize(), function(data) {
if((data) == 1) {
loadadminlayout();
//  alert(data);
}
else
{
alert(data);    
}
});
});

Is your $("#updatebusiness") an plain link (<a href="#" id="updatebusiness"> the user has to click? If yes then you should add and event.preventDefault() to prevent the browser from going anywhere, or rather use a <button> instead.

also: try .serialize() instead!

Since you are doing a POST .ajax is expecting the "data" property of the object you are passing it. You are setting the method to post and then setting up the url you are posting to as a get. You need to serialize your form and assign it to the data property or you need to change your ajax type to "GET"
