WordPress后台直接显示文章、页面、分类、标签和用户等ID号
有时我们需要查看某篇文章或者分类的ID,需要将鼠标放在文章或者分类名称上,然后查看浏览器状态栏上链接中的数字才能获得ID号,不够直观,可以将下面的代码添加到当前主题 functions.php 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’);
