wordpress如何在后台直接显示文章相关信息（分类id、标签id、用户id等）

wordpress如何在后台直接显示文章相关信息，其中包括（文章id、页面id、分类id、标签id和用户id等）。下面web建站小编给大家详细介绍一下具体实现方法！

在当前主题的functions.php文件中新增以下代码：

function ssid_column($cols) {
  $cols['ssid'] = 'ID';
  return $cols;
}

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;
}

function ssid_css() {
?>
<style type="text/css">
  #ssid { width: 50px; }
</style>
<?php
}

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');
