forum-specific advertising code

[woodysfj40]

Right now, I'm doing this by creating multiple templates....

template1 is the standard with google
template2 adds intellitxt
template3 is google/intellitxt free

I presently control ad display for usergroups with:
<if condition="is_member_of($bbuserinfo, 1,2,3,4,6,29)">adcode</if>

I'd also like to control ad display by forum, and am experimenting with some code that Dismounted has posted in the past...


<if condition="$foruminfo['forumid'] == 8">
adcode
<else />
altadcode
</if>

This works perfectly for the single forumid listed, however, I've yet to figure out how to apply the <if> statement to multiple forumid's....ie:

<if condition="$foruminfo['forumid'] == 8,27,56,4">

thanks for any assistance!
