I'm sending the variable like this:
xmlhttp.open("GET","insert-karma.php?pid=<? echo $pid; ?>",true);
The AJAX part doesn't seem to be the problem, if I check the Sript the PHP is echoing the integer correctly. (It displays the url as: insert-karma.php?pid=5
). However the PHP isn't getting the variable. (I tried echoing and it does't show anthing)
This is the PHP file:
// Connect to db;
$pid = $_POST['pid'];
$sql="UPDATE Poems SET Karma = Karma + 1 WHERE Pid = '$pid'";
// Disconnect form database;
What am I doing wrong? How do I manage to send $pid
to the PHP update-karma.php?
