我正在使用插件：WP Post-Template，它允许我使用自定义帖子类型的模板。

目前该插件监视theme root directory 对于包含以下内容的页面：

<?php
/**
* WP Post Template:  Template Name
*/
?>

我正在尝试编辑插件，以便将模板文件存储在它们自己的子目录中。看看插件代码，我想我已经找到了控制在哪里监视文件的代码行，但修改它时遇到了困难

$base = array( trailingslashit(get_template_directory()), trailingslashit(get_stylesheet_directory()) );

我试图查看的文件夹是：/lp/

这段代码更改了目录，但我在查看页面时看到了白色的死亡屏幕

$base = array( trailingslashit(get_template_directory().\'/lp/\'), trailingslashit(get_stylesheet_directory().\'/lp/\') ); 

我唯一的猜测是插件代码中还有更多需要编辑的内容
