Seems like POST values are lost when .htaccess RewriteRule used. GET values are OK. How to fix?
提问by Haradzieniec
Several days ago I had a question about removing index.php from the address bar, so the address of the page looks shorter and better. The shortest solution of this problem was (RewriteRule ^index.php / [L,R=301] in the .htaccess file). And it works!
前几天有一个问题，就是把地址栏里的index.php去掉，这样页面的地址看起来更短更好看。这个问题的最短解决方案是（RewriteRule ^index.php / [L,R=301] in the .htaccess file）。它有效！
Since I put that string into the .htaccess, some pages are redirected to the main page. I spent a lot of time to guess, why. As I understand, the answer is: with RewriteRule ^index.php / [L,R=301], $_POST parameters are not sent to the next page. $_GET parameters are OK.
Once I remove RewriteRule ^index.php / [L,R=301]from .htaccess, everything becomes fine as usual.
Why does it happen and how to fix that?
由于我将该字符串放入 .htaccess 中，因此一些页面被重定向到主页。我花了很多时间去猜测，为什么。据我了解，答案是： with RewriteRule ^index.php / [L,R=301], $_POST 参数不会发送到下一页。$_GET 参数没问题。一旦我RewriteRule ^index.php / [L,R=301]从 .htaccess 中删除，一切都会像往常一样好。为什么会发生这种情况以及如何解决？
Thank you.
谢谢你。

The [R]flag will incur a redirect. And user-agents issue a redirect as GETrequest. There is nothing that can be done if you really want to shorten URLs down to the /root path.
该[R]标志将导致重定向。并且用户代理发出重定向作为GET请求。如果您真的想将 URL 缩短到/根路径，则无能为力。
You could however block POST requests specifically from being rewritten/redirected:
但是，您可以专门阻止 POST 请求被重写/重定向：
RewriteCond %{REQUEST_METHOD} !POST
RewriteRule ^index.php / [L,R=301]

You could try using [L,R=307]instead. 307's must not change the request-method according to the spec, but I don't know how browser implemented 307.
您可以尝试使用[L,R=307]代替。307 不能根据规范更改请求方法，但我不知道浏览器是如何实现 307 的。
But the root of the problem is the use of <form action="____/index.php" ...
但问题的根源在于使用 <form action="____/index.php" ...
Just leave the action empty to POST to the current url e.g.
只需将操作留空即可发布到当前网址，例如

I'm using something like:
我正在使用类似的东西：
<IfModule mod_rewrite.c>
RewriteEngine on
RewriteCond %{REQUEST_URI} !^/(css|images|js)/
# don't rewrite existing files, directories and links
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-l
# rewrite everything else to index.php
RewriteRule .* index.php [L]
</IfModule>
And its working for all requests, rewriting it via index.php file. If you need to redirect 301 (which stands for Moved Permanently code) check out this question: Is it possible to redirect post data?
它适用于所有请求，通过 index.php 文件重写它。如果您需要重定向 301（代表永久移动代码），请查看以下问题：是否可以重定向发布数据？

POST values will NEVER survive an external redirect (the R=301), it's a security liability, so browsers will never support that. Remove the R=301and you will be fine. You just should alter all existing links to the page to the shorter/prettier one (<a>'s but also form actions etc.)
POST 值永远不会在外部重定向（the R=301）中幸存下来，这是一种安全责任，因此浏览器永远不会支持它。删除它R=301，你会没事的。您只需要将页面的所有现有链接更改为更短/更漂亮的链接（<a>'s 以及表单操作等）

I had the same problems but my htacces was like this:
我有同样的问题，但我的 htacces 是这样的：
RewriteEngine on
RewriteRule .* index.php [NC]
Just change NC for L and everything works fine.
只需将 NC 更改为 L，一切正常。
Final code:
最终代码：
RewriteEngine on
RewriteRule .* index.php [L]

In My case I used .htaccess. Refer : PHP $_POST not working?
就我而言，我使用了 .htaccess。参考：PHP $_POST 不工作？
i.e action="booking.php" to action="booking" worked for me
即 action="booking.php" 到 action="booking" 对我有用
