首先，您需要根据当前用户生成自定义设置。因此，需要满足两个条件：该设置必须仅可供当前用户访问，并且该设置必须是唯一的。

// Only do this for contributors and up
if (current_user_can(\'edit_posts\')) {
   // retrieve author id
   global $current_user;
   get_currentuserinfo();
   $author_id = $current_user->ID
   // generate customizer setting for this author only
   $wp_customize->add_setting( \'header_color_\' . $author_id , array(
     \'default\' => \'#000\',
     \'sanitize_callback\' => \'sanitize_hex_color\',
     \'capability\' => \'edit_posts\',
     ));

$author_id = get_the_author_meta(\'ID\');
get_mod(\'header_color_\' . $author_id);
