如何修改BuddyPress自定义通知链接实现点击后标记为已读

我在BuddyPress中创建了自定义通知，每当有新Topic发布时，内容会进入审核流程，所有版主都会收到通知和邮件，提醒其审核帖子。点击通知会跳转到对应话题页面，版主可在该页面执行批准或驳回操作，通知样式如下：

但我点击通知时，该通知不会被自动标记为已读。我了解到通知链接需要包含bbp_mark_read动作才能实现标记已读效果，但我找不到将该动作添加到通知URL的正确方法，我的代码如下：

// Display notification.
add_filter( 'bp_notifications_get_notifications_for_user', 'bbms_moderation_alert_notifications', 10, 5 );

function bbms_moderation_alert_notifications( $action, $item_id, $secondary_item_id, $total_items, $format = 'string' ) {

    // New custom notifications
    if ( 'bbms_moderation_alert_action' === $action ) {
        
        $post = get_post( $item_id ); //$item_id represents ID of the Topic
        $author_name = get_the_author_meta('display_name', $post->post_author);
        $custom_title = '[Moderate] ' .bp_core_get_user_displayname( $post->post_author ) . ' created a Topic "' . get_the_title( $item_id ) . '"';
        $custom_link  = get_permalink( $post ); //Need to create a wp_nonce_url with bbp_mark_topic action here
        $custom_text = '[Moderate] ' .bp_core_get_user_displayname( $post->post_author ) . ' created a Topic "' . get_the_title( $item_id ) . '"';

        // WordPress Toolbar
        if ( 'string' === $format ) {
            $return = apply_filters( 'bbms_moderation_alert_filter', '<a href="' . esc_url( $custom_link ) . '" title="' . esc_attr( $custom_title ) . '">' . esc_html( $custom_text ) . '</a>', $custom_text, $custom_link );
        // Deprecated BuddyBar
        } else {
            $return = apply_filters( 'bbms_moderation_alert_filter', array(
                'text' => $custom_text,
                'link' => $custom_link
            ), $custom_link, (int) $total_items, $custom_text, $custom_title );
        }

        return $return;
    }

    return $action;

}

我需要修改上述代码中的$custom_link变量，请问该如何操作？

直接替换原有$custom_link相关代码即可，修改后的完整代码如下：

// Display notification.
add_filter( 'bp_notifications_get_notifications_for_user', 'bbms_moderation_alert_notifications', 10, 5 );

function bbms_moderation_alert_notifications( $action, $item_id, $secondary_item_id, $total_items, $format = 'string' ) {

    // New custom notifications
    if ( 'bbms_moderation_alert_action' === $action ) {
        
        $post = get_post( $item_id ); //$item_id represents ID of the Topic
        $author_name = get_the_author_meta('display_name', $post->post_author);
        $custom_title = '[Moderate] ' .bp_core_get_user_displayname( $post->post_author ) . ' created a Topic "' . get_the_title( $item_id ) . '"';
        // 修改开始
        $base_permalink = get_permalink( $post );
        $custom_link = wp_nonce_url(
            add_query_arg(
                array(
                    'action' => 'bbp_mark_read',
                    'topic_id' => $item_id
                ),
                $base_permalink
            ),
            'bbp_mark_topic_' . $item_id
        );
        // 修改结束
        $custom_text = '[Moderate] ' .bp_core_get_user_displayname( $post->post_author ) . ' created a Topic "' . get_the_title( $item_id ) . '"';

        // WordPress Toolbar
        if ( 'string' === $format ) {
            $return = apply_filters( 'bbms_moderation_alert_filter', '<a href="' . esc_url( $custom_link ) . '" title="' . esc_attr( $custom_title ) . '">' . esc_html( $custom_text ) . '</a>', $custom_text, $custom_link );
        // Deprecated BuddyBar
        } else {
            $return = apply_filters( 'bbms_moderation_alert_filter', array(
                'text' => $custom_text,
                'link' => $custom_link
            ), $custom_link, (int) $total_items, $custom_text, $custom_title );
        }

        return $return;
    }

    return $action;

}

修改说明 #

1. 用add_query_arg方法在原话题永久链接上追加bbp_mark_read动作参数和对应话题ID参数，匹配bbPress原生的标记已读规则
2. 用wp_nonce_url生成带安全校验的链接，nonce规则bbp_mark_topic_{$item_id}完全匹配bbPress默认的校验逻辑，无需额外添加其他钩子即可生效
3. 版主点击通知后，bbPress会自动识别链接参数，校验通过后先将对应通知标记为已读，再跳转至话题详情页，不影响原有审核操作流程
