Check if a field is in a given set

[DeNasio]

Hello,

How do you check if a field is in a given set? I thought it was like this:

mysql_query("UPDATE Topics SET locked='yes' WHERE account='$account' AND topicid IN [".implode(",",$_POST['locked'])."]");

but I guess I was wrong.

could you please echo the query so that we can see what mysql sees?

you need () not []
