BuddyPress.org

Hello,

The ultimate goal is to mask the content and selector when a member arrives on the page of a public group to which it has not acceded. In fact he will see just the top of the page, and description button to join group

The idea is to reach over activities and other menu group visited oblige to register if he sees that description, avatar and the button to join

I found bp_group_is_member to test ()
http://buddypress.wp-a2z.org/oik_api/bp_group_is_member/
If I do not put any argument, I understand that it will test whether the member is party group (and I add the condition to be displayed in a group?

I have an error message:
« Fatal error: Call to undefined function bp_group_is_member() in /var/www/../wp-content/plugins/bp-custom.php on line 3 »

What I found to achieve the goal:

if ( !bp_group_is_member() || bp_is_active('groups') )
 {add_filter( 'bp_after_has_activities_parse_args', 'my_bp_activity_types_non-membre' );}
 
function my_bp_activity_types_non-membre( $retval ) {
    $retval['action'] = array(        
        //'activity_comment',
	//'activity_update',
	//'created_group',
	//'friendship_created', nouv relation entre membre
	//'joined_group',
	//'last_activity',
	//'new_avatar',
	//'new_blog_comment',
        //'new_blog_post',
	//'new_member',
	//'updated_profile',
	//'rtmedia_update'       
    ); 
    return $retval;

Regards
