大挖的后台今天突然发现了一处报错，if($unread_count = $wpjam_topic_messages[‘unread_count’]){刚开始以为是WPJAM BASIC插件的七牛云存储插件的问题，但是通过再次的设置并没有得到有效的解决，通过百度错误提示，发现了问题所在。

大挖安装的是WPJAM BASIC插件比较旧的版本的，只有2.6.2，通过代码的查看是因为一个WP问题的代码函数出现了问题，因为WPJAM BASIC插件的作品提供了一个简单的问答社区功能，但是其它大挖并不需要，所以直接在后台进行了注释隐藏，问题就有效的解决了。

通过插件的问题目标，找到路径所描述的插件”wpjam-basic/include/topic.php“文件，可以插件找到如下代码（大概在第83行到112行）：

add_filter(‘wpjam_pages’, ‘wpjam_topic_admin_pages’); add_filter(‘wpjam_network_pages’, ‘wpjam_topic_admin_pages’); function wpjam_topic_admin_pages($wpjam_pages){ $subs = array(); $menu_title = ‘WP问题’; if(wpjam_topic_get_weixin_user()){ $wpjam_topic_messages = wpjam_get_topic_messages(); if($unread_count = $wpjam_topic_messages[‘unread_count’]){ $menu_title .= ‘’.$unread_count.'’; } $subs[‘wpjam-topics’] = array(‘menu_title’=> ‘所有问答’, ‘function’=>’wpjam_topics_page’, ‘capability’ => ‘read’); $subs[‘wpjam-topic’] = array(‘menu_title’=> ‘我要提问’, ‘function’=>’wpjam_topic_edit_page’,’capability’ => ‘read’); $subs[‘wpjam-topic-user’] = array(‘menu_title’=> ‘个人资料’, ‘function’=>’wpjam_topic_user_page’,’capability’ => ‘read’); if(isset($_GET[‘page’]) && ($_GET[‘page’] == ‘wpjam-topic-messages’)){ $subs[‘wpjam-topic-messages’] = array(‘menu_title’=> ‘消息提醒’, ‘function’=>’wpjam_topic_messages_page’,’capability’ => ‘read’); } } $wpjam_pages[‘wpjam-topics’] = array( ‘menu_title’ => $menu_title, ‘icon’ => ‘dashicons-wordpress’, ‘subs’ => $subs, ‘capability’ => ‘read’ ); return $wpjam_pages; }

add_filter(‘wpjam_pages’, ‘wpjam_topic_admin_pages’);add_filter(‘wpjam_network_pages’, ‘wpjam_topic_admin_pages’);function wpjam_topic_admin_pages($wpjam_pages){ $subs = array(); $menu_title = ‘WP问题’; if(wpjam_topic_get_weixin_user()){ $wpjam_topic_messages = wpjam_get_topic_messages(); if($unread_count = $wpjam_topic_messages[‘unread_count’]){ $menu_title .= ‘’.$unread_count.‘’; } $subs[‘wpjam-topics’] = array(‘menu_title’=> ‘所有问答’, ‘function’=>‘wpjam_topics_page’, ‘capability’ => ‘read’); $subs[‘wpjam-topic’] = array(‘menu_title’=> ‘我要提问’, ‘function’=>‘wpjam_topic_edit_page’,‘capability’ => ‘read’); $subs[‘wpjam-topic-user’] = array(‘menu_title’=> ‘个人资料’, ‘function’=>‘wpjam_topic_user_page’,‘capability’ => ‘read’); if(isset($_GET[‘page’]) && ($_GET[‘page’] == ‘wpjam-topic-messages’)){ $subs[‘wpjam-topic-messages’] = array(‘menu_title’=> ‘消息提醒’, ‘function’=>‘wpjam_topic_messages_page’,‘capability’ => ‘read’); } } $wpjam_pages[‘wpjam-topics’] = array( ‘menu_title’ => $menu_title, ‘icon’ => ‘dashicons-wordpress’, ‘subs’ => $subs, ‘capability’ => ‘read’ ); return $wpjam_pages;}

将上面的所有代码注释掉或删除掉即可，上面的代码应该是将“WP问题”这个按钮添加到后台左侧导航的意思，只要将该函数删除即不会在左侧添加按钮了，也不影响插件的其他正常运行。为了插件的安全起见，我没有直接删除代码，而是选择注释。
