Php 通过post发送$服务器['；请求uri'；]

我得到了一个将值发送到php文件的常用表单

<form action=\"/admin/save\" method=\"post\" ENCTYPE=\"multipart/form-data\">
                            <div class=\"element\">
                        <label for=\"name\">Page ID <span class=\"red\">(required)</span></label>
                        <input id=\"id\" name=\"id\" value=".$edit['id']." class=\"text\" />

在第二个文件中，我想做一个链接返回，所以如果用户写错了什么，他点击那个链接，返回编辑页面（编辑页面链接看起来像这样-/admin/edit？id=5&lang=arm）。如何通过post方法而不是通过输入发送$\u SERVER['request\u uri']，我不想有其他输入。。或者你能在这里给我一些解决方案吗？

最简单的方法是有一个隐藏的输入：

<input type="hidden" name="previous_page" value="<?=$_SERVER['REQUEST_URI']?>" />

在您处理提交的文件中使用
$\u服务器['HTTP\u REFERER']
。
您是否考虑过使用？仅供参考，请参阅关于HTTP\u REFERER的信息-对于实时系统来说，它确实不可信。
