Re: Can functions in bp_template_tags.php be applied to a specific user ID?
As Paul said, those functions are intended to be used in a theme template. More specifically: they’re meant to be used inside of a member/group/activity/etc loop. So if you’re inside of a member loop
functions like bp_member_name() will automatically detect which member is currently being processed. There’s no need for a $user_id argument.
Most of the bp_has_x functions take arguments for specific members. For instance, bp_has_members( ‘include=3,7,24’ ) will make a loop of just those three members. Inside of that loop you can use any of the templatetags functions.
