Updating field in database

[Anon]

Hi,
i have a form which inserts data into a database. One of the fields in the database is called "replies". Everytime the user submits something i want "1" added to the replies field. To do this i am using a hidden field. My question is what do i need to do to the script to update the database for each form submission?

Thanx

$sql=mysql_query("UPDATE topic SET replies=replies+1 WHERE topic_id='$tid'");

or something similar

So you do not need a hidden field 🙂
