所以我有一个自定义的帖子类型“推荐”，它有一些。。。有趣的行为。昨天晚上，我有了这种类型的比赛，并创作了两份推荐信，其中一份名为“詹姆斯·布莱克伍德”
后来，我在写一篇新的帖子，标题是“关于我们”，当Wordpress（4.9.4）分配了一个slug时，它出现在了“JamesBlackwood”——我在这里不知所措。有什么好处？
以下是推荐内容类型的代码：

但奇怪的是，这个行为似乎与一个单独的元盒相关联，我将其包含在其中，以控制页面上一些“附加”的外观。。。当我关闭这个“Show Page Extras”元数据库时，上述行为就会消失。但是，如果metabox在那里，我检查“Show Client Certificational”并从两个选项中选择一个，它将从Certificational中替换slug名称。但不管这两个选择中的哪一个，总是詹姆斯·布莱克伍德（身份证较低的那个）。下面是该元框（其中包含一些jQuery）的代码：
function page_extras_get_meta( $value ) {
global $post;
$field = get_post_meta( $post->ID, $value, true );
if ( ! empty( $field ) ) {
return is_array( $field ) ? stripslashes_deep( $field ) : stripslashes( wp_kses_decode_entities( $field ) );
} else {
return false;

从昨晚8点左右开始，我一直在用九种不同的方式来看待这个问题，我不知所措。我想我已经想得太多了。还有人有什么想法吗？
