将下面的代码添加到当前 functions.php 主题文件中,之后会在后台文章、分类等列表后面直接显示ID号:
// Prepend the new column to the columns array function ssid_column($cols) { $cols['ssid'] = 'ID'; return $cols; } // Echo the ID for the new column function ssid_value($column_name, $id) { if ($column_name == 'ssid') echo $id; } function ssid_return_value($value, $column_name, $id) { if ($column_name == 'ssid') $value = $id; return $value; } // Output CSS for width of new column function ssid_css() { ?> <style type="text/css"> #ssid { width: 50px; } /* Simply Show IDs */ </style> <?php } // Actions/Filters for various tables and the css output function ssid_add() { add_action('admin_head', 'ssid_css'); add_filter('manage_posts_columns', 'ssid_column'); add_action('manage_posts_custom_column', 'ssid_value', 10, 2); add_filter('manage_pages_columns', 'ssid_column'); add_action('manage_pages_custom_column', 'ssid_value', 10, 2); add_filter('manage_media_columns', 'ssid_column'); add_action('manage_media_custom_column', 'ssid_value', 10, 2); add_filter('manage_link-manager_columns', 'ssid_column'); add_action('manage_link_custom_column', 'ssid_value', 10, 2); add_action('manage_edit-link-categories_columns', 'ssid_column'); add_filter('manage_link_categories_custom_column', 'ssid_return_value', 10, 3); foreach ( get_taxonomies() as $taxonomy ) { add_action("manage_edit-${taxonomy}_columns", 'ssid_column'); add_filter("manage_${taxonomy}_custom_column", 'ssid_return_value', 10, 3); } add_action('manage_users_columns', 'ssid_column'); add_filter('manage_users_custom_column', 'ssid_return_value', 10, 3); add_action('manage_edit-comments_columns', 'ssid_column'); add_action('manage_comments_custom_column', 'ssid_value', 10, 2); } add_action('admin_init', 'ssid_add');
代码来自插件:Simply Show IDs
当然你也可以直接安装该插件。
