gistfile1.php

i have a file called wantbtn.php that has this in it

<?php $wantclick = mysql_query("INSERT INTO user (itemtype, totalcost, karmacost, imagename. namebrand, wantedstatus)
SELECT itemtype, totalcost, karmacost, imagename. namebrand, wantedstatus
FROM allitems") 
or die(mysql_error());
?>

when you click wantIt, i want the above to happen

This is the JS I tried
<script>
  	$('.item').each(function(){
		    $('.wantIt', this).click(function(e){
		        e.preventDefault();
		        $.post(
		            'includes/wantbtn.php'
		        );
		    });
		});
	</script>

<script> $(function(){ $('.wantIt').click(function(e){ e.preventDefault(); $.post( 'includes/wantbtn.php' ); }); }); </script>
