mod_rewrite: Redirect request to subdir with many subfolders of different structures + redirect to index.php

问题

I need to create a following rule to place in my .htaccess

1. For each request i'd like to execute file/path in subfolder subdir.
2. If the file doesn't exist there then i'd like to forward this request to index.php

Let say that .htaccess iw placed at http://domain/folder

When the user opens url http://domain/folder/Subfolder/xxx.html he should recieve file from http://domain/folder/subdir/Subfolder/xxx.html

So these rules have to consider the fact that there are subfolders inside subdir. (Different structures of subfolders :-) And only if the path under subdir doesn't exist the request should be forwarded to index.php

Plase help :)

ps This is a followup question to my previous one. It is quite different and includes the fact that there are subfolders inside subdir. -> mod_rewrite: How to search in local folder, subfolder and then redirect to index.php

回答1:

This should do it:

RewriteEngine on
RewriteBase /

RewriteCond %{ENV:REDIRECT_STATUS} 200
RewriteRule ^ - [L]

RewriteCond %{REQUEST_URI} ([\w]+\.[\w]+)$ [NC]
RewriteCond %{DOCUMENT_ROOT}/%1 -f 
RewriteRule ^ /%1 [NC,L] 

RewriteCond %{DOCUMENT_ROOT}/subdir%{REQUEST_URI} -f
RewriteRule ^ /subdir%{REQUEST_URI} [L]

RewriteRule ^ /index.php [L]

---

An update with a slight optimization.

RewriteEngine on
#RewriteBase /

RewriteCond %{ENV:REDIRECT_STATUS} 200
RewriteRule ^ - [L]

RewriteCond %{REQUEST_FILENAME} -f
RewriteRule ^[^/]+\.[^/]+$ - [NC,L]

RewriteCond %{REQUEST_FILENAME} (.*/)([\w]+\.[\w]+)$ [NC]
RewriteCond %1subdir/%2 -f
RewriteRule ^ subdir/%2 [L]

RewriteRule ^ index.php [L]

• The above will work with anydirectory/subdir

Change log:

• RewriteBase commented for use of relative path.

• Checking for /file.ext (or whether in current directory). the below will check whether file is present in current directory.

  RewriteCond %{REQUEST_FILENAME} -f
RewriteRule ^[^/]+\.[^/]+$ - [NC,L]

• RewriteCond %{DOCUMENT_ROOT}/subdir%{REQUEST_URI} -f

  captures current directory in %1 and the file.ext in %2

Why not simply use an Alias:

Alias /folder /subdir

And redirect to index.php in your 404 page? It has the advantage, 404 is still caught into the weblog.

回答3:

Try adding the following to the .htaccess file in the root/folder directory of your site.

RewriteEngine on
RewriteBase /folder

#capture the Subfolder/file.xx
RewriteCond %{REQUEST_URI} ^/[^/]+/([^/]+)$
#if the subdir/subfolder/file.xx exists
RewriteCond %{DOCUMENT_ROOT}/subdir/%1 -f  
#Serve this file
RewriteRule ^ /subdir/%1 [L,S=1]
#else send to index.php in root directory  
RewriteRule ^  /index.php [L]  

I am assuming you want to send the request to the index.php in the root dir. If it is in the folder directory instead, change the last rule to

RewriteRule ^  index.php [L]
