Re: emptying session variables?

["Gideon van Gelder" <gideon@swingmaster.nl>]

I'm not sure, but I bet you could do this:

[set del]
&set=feedback_subject ""
[/set]

<input type="hidden" name="mv_check" value="del">

I think this first uses the former value and then, after update replaces it
with "".
