如何使RewriteCond更改THE_REQUEST而不更改REQUEST_METHOD

Question

I got this rewrite rule from the internet:

# To externally redirect /dir/foo.php to /dir/foo
RewriteCond %{THE_REQUEST} ^[A-Z]{3,}\s([^.]+)\.php [NC]
RewriteRule ^ %1 [R,L,NC]

The rule works well, but now when I try to send a POST message, this rule will rewrite also the method to GET. This is my form:

<form action="check.php" method="post">
<input type="text" name="email" id="email"/>
<input type='submit' value='check'>
</form>

This is what I got from the server (var_dump($_SERVER))

["REQUEST_METHOD"]=>
string(3) "GET"

I am not really familiar with rewrite rules. Could you tell me how to fix it so that it still process php file extensions but wont touch the REQUEST_METHOD part (from POST to GET)?

Thank you.

UPDATE FULL RULE:

Options +FollowSymLinks -MultiViews
# Turn mod_rewrite on
RewriteEngine On
RewriteBase /


# To externally redirect /dir/foo.php to /dir/foo
RewriteCond %{THE_REQUEST} ^[A-Z]{3,}\s([^.]+)\.php [NC]
RewriteRule ^ %1 [L,NC] #[R,L,NC]


## To internally redirect /dir/foo to /dir/foo.php
RewriteCond %{REQUEST_FILENAME}.php -f [NC]
RewriteRule ^ %{REQUEST_URI}.php [L]

Answer 1

This is how your .htaccess should look like:

Options +FollowSymLinks -MultiViews 

RewriteEngine On
RewriteBase /

# To externally redirect /dir/foo.php to /dir/foo
RewriteCond %{THE_REQUEST} ^[A-Z]{3,}\s([^.]+)\.php [NC]
RewriteRule ^ %1 [R,L]

## To internally redirect /dir/foo to /dir/foo.php
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{DOCUMENT_ROOT}/$1\.php -f
RewriteRule ^(.+?)/?$ $1.php [L]

You should never use comments on the same lines of the conditions and rules on the .htaccess like this:

RewriteRule ^ %1 [L,NC] #[R,L,NC]

As it will break the .htaccess from working, comments should be always on a new line.

This is how your form should look like:

<form action="http://domain.com/check" method="post">
<input type="text" name="email" id="email"/>
<input type="submit" value="check">
</form>

This should properly return you with the value you want as a POST method.

array(1) { ["email"]=> string(4) "text you typed on the input box" } 

Answer 2

You are doing a redirect [R] - so you are posting to a location which is just dumping the POSTed data and redirecting the request (HTTP GET). The post should be pointed to /dir/foo which could be passed to /dir/foo.php, but you're current .htaccess doesn't allow for that.

Your form should look something like:

<form action="/check" method="post">
      <input type="text" name="email" id="email"/>
      <input type='submit' value='check'>
</form>

Here's an example of internal routing to .php files.

 RewriteEngine On
 RewriteCond %{REQUEST_FILENAME} !-f  # As long as it's not a file
 RewriteCond %{REQUEST_FILENAME} !-d  # As long as it's not a directory
 RewriteRule (.*) $1.php [L,QSA]

Hope that points you in the right direction.
