问题
So I'm trying to get a mod_rewrite rule to redirect requests to a php-script with an .htaccess file. The thing is, I want it to work regardless of where I put the project on a webserver (the .htaccess file and the php-script are always in the same folder).
The rewrite itself is very simple. If the script and the .htacess are in the directory /path/to/project and the user visits:
/path/to/project/somestring
it should be rewritten to:
/path/to/project/index.php?t=somestring
This should work for every subdirectory at any level in the webserver. So:
If the php-script and the .htaccess files are in the root:
/somestring2
should be rewritten to:
/index.php?t=somestring2
If the php-script and the .htaccess file are in /subdirectory:
/subdirectory/somestring3
should be rewritten to:
/subdirectory/index.php?t=somestring3
So the RewriteRule should perform the same rewrite action regardless of where the project lives within the server. The string that is to become a GET-parameter can consist of those characters: [a-zA-Z0-9]. If there are other GET-parameters in the requested URL, they should be appended as well (hence the QSA flag). This is what I've tried:
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*/)([a-zA-Z0-9])/? $1index.php&t=$2 [L,QSA]
However, this results in a 404 error. How can I alter it to do what I want?
回答1:
Try :
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^(.*/)?([A-Za-z0-9]+)/?$ /$1index.php?t=$2 [NC,L,QSA]
Note that a leading slash in rewrite pattern is not required in the RewriteRule context.
