我有一些代码，可以将自定义字段添加到自定义帖子类型的快速编辑和批量编辑部分。以下是我使用的内容：https://github.com/bamadesigner/manage-wordpress-posts-using-bulk-edit-and-quick-edit

一切都很好，只是我无法从快速编辑中保存。批量编辑可以正常工作并保存，只是快速编辑不会保存任何更改。以下是我认为相关的代码。谁能告诉我做错了什么吗？

完整更新了下面的代码。

PHP for Quick Edit Plugin

<?php

/**
 * Plugin Name: Manage WordPress Posts Using Bulk Edit and Quick Edit
 * Description: This is the code for a tutorial WP Dreamer wrote about managing WordPress posts using bulk and quick edit.
 * Author: WP Dreamer
 * Author URI: http://wpdreamer.com/2012/03/manage-wordpress-posts-using-bulk-edit-and-quick-edit/
 */

/**
 * I decided to convert the tutorial to a plugin format
 * so I could easily monitor it on my development environment
 * and store it on GitHub.
 *
 * With that said, you could easily take this code and paste it
 * into your theme\'s functions.php file. There is, however,
 * an included javascript file so be sure to check the
 * manage_wp_posts_be_qe_enqueue_admin_scripts()
 * function to confirm you\'re enqueueing the right javascript file.
 *
 * Also, after a few requests for custom field examples other than
 * text boxes, I updated the tutorial to include a select dropdown
 * and a radio button.
 *
 * Custom Fields:
 * \'Release Date - input text
 * \'Coming Soon\' - input radio
 * \'Film Rating\' - select dropdown
 *
 * If you find any issues with the tutorial, or code, please let me know. Thanks!

/**
 * Since Bulk Edit and Quick Edit hooks are triggered by custom columns,
 * you must first add custom columns for the fields you wish to add, which are setup by
 * \'filtering\' the column information.
 *
 * There are 3 different column filters: \'manage_pages_columns\' for pages,
 * \'manage_posts_columns\' which covers ALL post types (including custom post types),
 * and \'manage_{$post_type_name}_posts_columns\' which only covers, you guessed it,
 * the columns for the defined $post_type_name.
 *
 * The \'manage_pages_columns\' and \'manage_{$post_type_name}_posts_columns\' filters only
 * pass $columns (an array), which is the column info, as an argument, but \'manage_posts_columns\'
 * passes $columns and $post_type (a string).
 *
 * Note: Don\'t forget that it\'s a WordPress filter so you HAVE to return the first argument that\'s
 * passed to the function, in this case $columns. And for filters that pass more than 1 argument,
 * you have to specify the number of accepted arguments in your add_filter() declaration,
 * following the priority argument.
