In which template are you trying to accomplish this? If it is inside some postbit template then
You could also add
$post['usergroup']
and $post['additionalgroups']
are the two variables you need.<if $post['usergroup'] == 1 || my_strpos(','.$post['additionalgroups'].',', ',1,') then>
foo
</if>
You could also add
is_member()
to the white list file of functions allowed. Or perhaps it is already there, I don't know.
