WordPress網(wǎng)站后臺默認(rèn)情況下是不顯示分類目錄和文章的ID號的，有時我們在調(diào)用分類內(nèi)容時，需要使用到分類列表顯示ID號.

1.打開函數(shù)文件functions.；

2.在模板函數(shù)文件里添加以下的函數(shù)代碼，然后保存；

/*** 為WordPress后臺的文章、分類等顯示ID*/// 添加一個新的列 IDfunction?ssid_column($cols)?{$cols['ssid']?=?'ID';return?$cols;}// 顯示 IDfunction?ssid_value($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;}// 為 ID 這列添加cssfunction?ssid_css()?{?><style type="text/css">#ssid { width: 50px; } /* Simply Show IDs */</style><?}// 通過動作/過濾器輸出各種表格和CSSfunction?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-ments_columns',?'ssid_column');add_action('manage_ments_custom_column',?'ssid_value',?10,?2);}add_action('admin_init',?'ssid_add');

3.這樣自己的網(wǎng)站后臺就會顯示文章、分類列表ID了。
