On my Prayer request site, i let users Click a button to Pray for somone that has posted a pray, i got that all set up but.

Code: // connect to db...

if ($_GET['id']) {
$id = (int) $_GET['id'];
$sql = "update table set column=column+1 where id=$id";
mysql_query($sql);
}
I want my users to beable to only Pray for a user once each, and then not beable to prayer for that user anymore, for each session
