Doesn't seem to work!

No worries.

I found the bp_get_member_latest_update filter which I then used to return an empty string if the user (with the activity) is blocking you as the viewer.

Found the issue.
It seems I updated the wrong file and left out the function.

In the bpb-queries.php file there should be in the end:

/**
 * Block Activity View
 * If the user listed is blocking us, we will not be able to see
 * their activities.
 * @since 1.0
 * @version 1.0
 */
function bpb_remove_activity_if_blocked( $update_content ) {
	global $members_template;

	if ( !empty( $members_template->member->id ) )
		$user_id = $members_template->member->id;
	elseif ( bp_displayed_user_id() )
		$user_id = bp_displayed_user_id();

	$users_list = bpb_get_blocked_users( $user_id );
	if ( in_array( get_current_user_id(), $users_list ) && ! current_user_can( 'edit_users' ) )
		return '';

	return $update_content;
}

Are you going to update the repository?

It should be updated

Still not working on the activity stream! ??

I only added the filter for the members list page. I see what you mean now, I forgot the activity page. I’ll get on it.

I pushed though one solution for now. It is not perfect and could use a better approach but it is 4AM here so I will not get it done without some sleep. Any suggestions on how to best filter activities are welcomed. When it comes to members it was pretty easy to just hook into BP_User_Query but I cant find a way to do similar stuff with activities.

Hi Gabriel,
You are getting closer to resolving this. However there is no need for the block buttons on the activity or the message. Basically the entire activity needs to be blocked as if the person did not exist. That means no avatar of a blocked person, no message that they are blocked, and no button. I hope you get some rest and can figure this out when rested. You are so close to nailing this down. Thanks for the update, it definitely shows you are working to get this plugin on track!

After some good night sleep, I immediately found a way to hook in and filter our activities ??
So in Beta5. You can no longer see activities you block and activities of those who block you.

Also added a constant to allow you to set which capability to check for when it comes to who can not be blocked (as in admins).

Hi Gabriel,
I just tested beta5 and if you block a persons activity then the person that has been blocked can no longer see the person who blocked them’s activity. However I noticed some strange behavior. After the person that has blocked someone starts posting on the sitewide activity stream, it makes the person who was blocked activity stream start to diminish to where the person that was blocked does even see their own activities or the other users activities that has not blocked them. Your getting closer though. Hopefully you can find a fix! Thanks!

Hi just checking to see if you have found a solution to my last reply above? Thanks!
