Question

我正在尝试从前端和wordpress中的后端向自定义表插入数据。下面是我的代码，如果我从后端插入数据它的工作，但如果我尝试从前端插入它给我错误404。

 <?php

我该如何解决这个问题？请帮帮我

我预计您遇到的问题与您使用'name'的“保留”帖子变量名称有关。

The WordPress Codex page for Register_Taxonomy()包含“保留条款”列表。

此外，form标记上的action attribute内容遗失了您的网址。这在当前的浏览器中处理正常，但在某些旧版浏览器中可能会导致意外行为，并且不能保证将来可以使用。

更好的做法是完全删除此属性，如果您不打算使用它，因为the spec strongly discourages authors from leaving it empty：

action和formaction内容属性，如果指定，必须的值为valid non-empty URL potentially surrounded by spaces。

（此信息取决于action属性，感谢@mercator和this answer）
