我正在尝试清理错误日志。仍然会生成此错误：
[Tue Apr 24 06:09:32 2012] [error] [client 44.444.69.28] PHP Notice: Undefined index: current_id in /srv/www/virtual/website.com/htdocs/wp-content/themes/mimbo/sidebar.php on line 12
来自此代码：
$posts = get_posts('numberposts=4&exclude=' . isset($GLOBALS['current_id']) ? $GLOBALS['current_id'] : '' . '&category='. $category->term_id);
我也试过这个：
$posts = get_posts('numberposts=4&exclude=' . array_key_exists('current_id',$GLOBALS) ? $GLOBALS['current_id'] : '' . '&category='. $category->term_id);
我添加了if / else短码来检查我认为可以消除错误的当前id，但它仍然没有消失。
