<form name="frm2sub" id="frm2sub" action="page3.php" method="post">
<input type="submit" name="submit" value="Submit" id="submit" />
</form>
</div>

This is my jquery function:

$("#frm2sub").submit( function() {  
    var values = {};
values["fname"] = $("#fname").val();
});

I can do this for each one of the input boxes but I want to give all this data to the next page. So how do I put this array into $_POST? Btw, I've tried doing

var data = $("#reg2a").serialize();

and

var data = $(document).serialize();

Data ended up being empty. Any ideas? Thanks
