如果您使用的是WP 3.0+，则应该能够使用register\\u post\\u status（）方法将新状态注册为public。我还没有在法典中看到它，但下面是记录的内容：

/**
 * Register a post type. Do not use before init.
 *
 * A simple function for creating or modifying a post status based on the
 * parameters given. The function will accept an array (second optional
 * parameter), along with a string for the post status name.
 *
 *
 * Optional $args contents:
 *
 * label - A descriptive name for the post status marked for translation. Defaults to $post_status.
 * public - Whether posts of this status should be shown in the admin UI. Defaults to true.
 * exclude_from_search - Whether to exclude posts with this post status from search results. Defaults to true.
 *
 * @package WordPress
 * @subpackage Post
 * @since 3.0.0
 * @uses $wp_post_statuses Inserts new post status object into the list
 *
 * @param string $post_status Name of the post status.
 * @param array|string $args See above description.

function register_post_status($post_status, $args = array()) {....

function add_pitch_status() {
    register_post_status(\'pitch\', array(\'public\'=>true));
}
add_action(\'init\', \'add_pitch_status\');
