wordpress - WordPress 管理员过滤器在多重过滤中无法正常工作（仅读取最后一个过滤器）

Question

我创建了一个名为“cliente_finale”的自定义帖子类型。

我有一些自定义字段，一切正常。

我在“edit.php”中进行自定义过滤时遇到了麻烦。

我已经创建了 2 个自定义过滤器，如果单独使用或与其他所有默认 WordPress 过滤器一起使用，它们可以正常工作。但是当它们一起使用时，我只能看到最后的过滤结果（按钩子优先级排序）。

我认为我的查询结果在某种程度上被“最后一个”（优先级）过滤器覆盖。

我没有找到解决方案，可能是因为缺少 WordPress 核心功能。

这是此过滤器的代码...
