htaccess中的动态URL重写

Question

I've a url like :

http://localhost/project/gallery_detail.php?id=3

what I want here is :

http://localhost/project/USERNAME/3

What I'm trying is :

RewriteEngine 
OnRewriteRule /(.*)/(.*)/$ gallery_detail.php?id=$1

and handling this to php file but didn't succeed.

Answer 1

 RewriteRule /(.*)/(.*)/$ gallery_detail.php?id=$1 

In per-directory .htaccess files, the URL-path never starts with a slash. You are also only capturing 2 groups, when you need 3 and are using the first (ie. project ) in the substitution .

Try something like the following instead, if your .htaccess file is located in the document root (ie. localhost/.htaccess ).

RewriteRule ([^/]+)/[^/]+/(\d+)$ $1/gallery_detail.php?id=$2 [L]

You don't need to capture groups if you don't need them. [^/]+ is for 1 or more characters, other than slash (the directory separator).

UPDATE: However, if the .htaccess file is located in the /project subdirectory then change this to:

RewriteRule [^/]+/(\d+)$ gallery_detail.php?id=$1 [L]
