BuddyPress.org

Hey all I’m attempting to modify the content returned by BuddyPress’ default ‘@’ mention notification. I’m using this as part of a custom profile page and would like to modify the “username mentioned you’ text to something more personalized based on post type.

// Change mention output
function format_mention_notifications( $action, $item_id, $secondary_item_id, $total_items, $format = 'string', $component_action, $component_name, $notification_id) {
    if ( $component_action === 'new_at_mention') { // User mentioned notification

        $mentioned_source_type = get_post_type($item_id);
        $username = wl_get_username($secondary_item_id);
        $mention_avatar = wl_get_avatar($secondary_item_id);
        $mention_title = '';
        $mention_text = $username;

        if ($mentioned_source_type == 'topic') {
            $mention_title = bbp_get_topic_title( $item_id );
            $mention_text .= ' mentioned you in the forum post ';
            $mention_source_link = ''; // link to topic
        } else if ($mentioned_source_type == 'reply') {
            $parent_topic_id = bbp_get_reply_topic_id( $item_id );
            $mention_title = bbp_get_topic_title( $parent_topic_id );
            $mention_text .= ' mentioned you in their response to the forum post ';
            $mention_source_link = bbp_get_reply_url( $item_id ); // link to reply
        } else if ($mentioned_source_type == 'comment') {
            $comment = get_comment($item_id);
            $mention_text .= ' mentioned you in their comment';
            $mention_source_link = get_comment_link($comment);

        } else {
            $mention_avatar = '';
            $mention_title = get_the_title($item_id);
            $mention_text = 'You were mentioned in ';
            $mention_source_link = get_permalink($item_id);
        }

        $mention_source_link = wp_nonce_url( add_query_arg( array( 'action' => 'read', 'notification_id' => $notification_id), $mention_source_link ), 'bp_notification_mark_read_' . $notification_id);

        // WordPress Toolbar
        if ( 'string' === $format ) {
            $return = apply_filters( 'bp_activity_single_at_mentions_notification', '<a href="' . esc_url( $mention_source_link ) . '" title="New mention">'. $mention_avatar . esc_html( $mention_text ) . '<span class="activity-title">'.$mention_title.'</span></a>', (int) $total_items, $mention_text, $mention_source_link );

        // Deprecated BuddyBar
        } else {
            $return = apply_filters( 'bp_activity_single_at_mentions_notification', array(
                'text' => $mention_text . $mention_title,
                'link' => $mention_source_link
            ), $mention_source_link, (int) $total_items, $mention_text, $mention_title );
        }
    }

    return $return;

}
add_filter( 'bp_notifications_get_notifications_for_user', 'format_mention_notifications', 100, 8 );

What I’ve tried so far:
– Changing the priority of the filter
– Moving my logic into the activity_format_notifications action with various different priorities
– All of the above in a custom plugin file, bp-custom.php, and my themes’ function.php file

I’ve used a similar filter for custom notifications and that aspect works great. I just can’t seem to override the default content with my own. My thoughts are that the the filters/actions run too late to be noticed by BuddyPress.

Many thanks for your help.
