我想创建一个WP自定义帖子类型插件。我尝试过使用ACF插件并生成自定义字段：http://pastebin.com/Nz7f8ARw。
我不知道如何使用上面生成的字段创建独立的插件而不使用ACF插件。
我尝试使用以下代码，但不知道如何继续进行。
<?php
/*Plugin Name: CNSLounge
Description: This plugin registers the 'Authors CNSLounge' post type.

// Register Custom Post Type
function CNSLounge() {
$labels = array(
'name' => _x( 'Authorz', 'Post Type General Name', 'text_domain' ),
'singular_name' => _x( 'Authorz', 'Post Type Singular Name', 'text_domain' ),

function CNSLounge() {
