在第二个文件中，我想要回复一个链接，所以如果用户写错了，他点击该链接，返回编辑页面（编辑页面链接看起来像这样 - / admin / edit？id = 5＆amp;郎=臂）。我如何通过post方法发送$ _SERVER ['request_uri']但不是通过输入，我不想让它有另外的输入..或者你可以在这里给我任何解决方案吗？

最简单的方法是隐藏输入：
<input type="hidden" name="previous_page" value="<?=$_SERVER['REQUEST_URI']?>" />
然后，您可以通过$_POST['previous_page']访问上一页的URI。

在处理提交的文件中使用$_SERVER['HTTP_REFERER']。
