我几周前添加了这段代码，但它昨晚突然停止工作，怎么可能呢？它在本地服务器上运行正常，但在共享主机上运行不正常。本地运行PHP 5.5.3并且主机运行5.4，但我现在提出将该特定子域升级到5.5的请求以防万一正在运行。
使用子主题。父主题创建一个名为Portfolio的自定义帖子类型，其中所有帖子的slug为/ portfolio-item /。在我的孩子主题中，我添加了两件事：1。一个名为Hidden Pages的新自定义帖子类型，我使用了我在网上发现的代码删除了slug，所以它只是domain.com/page-name。 2.我添加了更多代码，引用了投资组合类型，这也删除了slug。
一切都工作得很好，但突然之间，所有标准页面404（并隐藏在后端，但不在数据库中，这不是数据库问题！），并且投资组合的帖子被神奇地移动到了博客（常规标准帖）。如果您注释掉custom_pre_get_posts行（132），则问题将解决。但客户需要网站清洁而没有slu ..所以我不想保持原样。

这是指这一行：
$post_name = end(explode('/', trim($post_path, '/')));
这仍然在错误日志中，但在更改后，它不在管理员端，是否意味着它已修复？
子主题代码来自此处：https://gist.github.com/stefanbc/6620151和http://www.markwarddesign.com/2014/02/remove-custom-post-type-slug-permalink/
因此，如果有人知道如何修改此文件以将所有内容恢复到完美的工作状态，那就太好了。实际上，我们距离发射还有几天的时间。 EEP。谢谢！
答案 0 :(得分：0)
问题不在于Wordpress，因为错误说明了，它都是纯PHP。你应该在那一行做一点改动（用括号包裹explode()）：
$post_name = end((explode('/', trim($post_path, '/'))));
答案 1 :(得分：0)
鉴于我的PHP级别并且不想重写涉及父级和子级主题功能的代码，我无法找到解决此问题的方法。我最终删除了所有试图删除slug的代码。我越过我的手指安装了这个过时的插件，它工作。因此，对于任何未来参考的人，我想你可以避免代码而只是使用它！
