Hello,

Please use the following code. It will send email notification to all group members on new activity update,

function buddydev_mail_on_new_group_activity( $user_ids, $args ) {

	if ( empty( $user_ids ) ) {
		return;
	}

	$user_emails = array_map( function ( $user_id ) {
		$user = get_user_by( 'id', $user_id );

		if ( ! $user ) {
			return;
		}

		return $user->user_email;
	}, $user_ids );

	$user_emails = array_filter( $user_emails );

	if ( ! $user_emails ) {
		return;
	}

	$group                      = new BP_Groups_Group( $args['group_id'] );
	$loggedin_user_display_name = bp_get_loggedin_user_fullname();

	$activity = new BP_Activity_Activity( $args['activity_id'] );

	$activity_content   = $activity->content;
	$activity_permalink = bp_activity_get_permalink( $activity->id, $activity );

	$subject = sprintf( '%1$s posted to %2$s', $loggedin_user_display_name, $group->name );

	$message = <<<MAIN
Hi,
	
{$loggedin_user_display_name} posted...
	
{$activity_content}

Link: {$activity_permalink}
MAIN;

	wp_mail( $user_emails, $subject, $message );
}
add_action( 'bp_group_activities_notify_members', 'buddydev_mail_on_new_group_activity', 10, 2 );

Please do let me know if it works or not.

Regards
Ravi

Hello,

I use this plugin to generate group notification in Buddypress.
But when user publish post with picture or document without text, the pluggin use an old activity id.
Have you tested this problem ?

Thanks
