在wordpres程序后台显示文章和页面列表的ID

id一直是开源程序的优化和特性在wordpress中也不例外，只是在wordpress中id隐藏在链接中挺链接查看id号已经成为wordpress开发者的下意识形为但是对刚刚接触到wordpress的小白这种体现方法不太适用，所以要把id列在后台的明显位置或是列表中这样不旦方便查看而且方便记录，只需要一段代码添加到functions.php函数尾部或是开发功能即可成生。简单实用

<?phpadd_filter('manage_posts_columns', 'wpjam_id_manage_posts_columns');add_filter('manage_pages_columns', 'wpjam_id_manage_posts_columns');function wpjam_id_manage_posts_columns($columns){$columns['post_id'] = 'ID';return $columns;}add_action('manage_posts_custom_column','wpjam_id_manage_posts_custom_column',10,2);add_action('manage_pages_custom_column','wpjam_id_manage_posts_custom_column',10,2);function wpjam_id_manage_posts_custom_column($column_name,$id){if ($column_name == 'post_id') {echo $id;}}?><?phpadd_filter('manage_posts_columns', 'wpjam_id_manage_posts_columns');add_filter('manage_pages_columns', 'wpjam_id_manage_posts_columns');function wpjam_id_manage_posts_columns($columns){$columns['post_id'] = 'ID';return $columns;}add_action('manage_posts_custom_column','wpjam_id_manage_posts_custom_column',10,2);add_action('manage_pages_custom_column','wpjam_id_manage_posts_custom_column',10,2);function wpjam_id_manage_posts_custom_column($column_name,$id){if ($column_name == 'post_id') {echo $id;}}?>
