so if the blocked user can see the activity events from the blocker, are they able to comment on them there?

Erro in Elgg 2.3.2

Can someone help me with this problem? Any idea? Important network user may be able to block another user. Does anyone have any type and block on the network that can help?

Hi @Vagsiarom, The plugin worked fine with Elgg 2.3.3. I blocked a user and then I tried to view the user profile and it showed me the blocked page with the message "You are trying to view content from or perform an action on a user that you have blocked. To see this user's content, you must first unblock the user."

Do let me know how did you got the error? What action were you performing? A little more details would help.

Only looked at the code and not tried myself. But I think it might help to change line 172 of start.php a little bit. The modified code would be

function check_page_owner($event, $type, $return) {
    $page_owner = elgg_get_page_owner_entity();
    if ((!$page_owner) || (!$page_owner instanceof \ElggUser)) {
        return null;
    }

checking also if $page_owner is a user entity (as this might not be always the case - for example not in groups).

Iionly! Now another problem with user lock plugin. When you are going to send a message to a new name, see the error below:

$user = get_user_by_username(get_input('recipient_username'));

I think in later versions of the messaging plugin the input changed, you'll need to see what is passed and correct accordingly.  There is no get_input('recipient_username') so $user ends up being null which triggers the error.

I think it should work with modifying the messages_send_action() function in start.php to

function messages_send_action($hook, $type, $return, $params) {
    $recipients = (array) get_input('recipients');

    if (empty($recipients)) {
        register_error(elgg_echo("messages:user:blank"));
        forward("messages/compose");
    }

    $recipient = (int) elgg_extract(0, $recipients);
    $user = get_user($recipient);

    if (is_blocked(elgg_get_logged_in_user_entity(), $user)) {
        elgg_make_sticky_form('messages');
        register_error(elgg_echo('block_users:blocked_content_notice'));
        return false;
    }
}

But as I don't use this plugin I haven't tested the code.

Thank you Matt.

Blocked user can comment on my blog from the activity stream. That sort of defeats the purpose of blocking,
