问题描述

我有一个问题CodeIgniter .htaccess文件，希望有人可以帮助我！
我不知道正则表达式或如何使用.htaccess，我对这个东西很新！

我的问题是：

我有这种文件结构（多应用程序）：

   -  application 
  -  admin 
  -  site 
  -  system 
  -  index.php 
  -  admin.php 
  

这个.htaccess（在localhost上可以正常工作。）

  FollowSymLinks 
选项-Indexes 
 DirectoryIndex index.php 
 
 RewriteEngine on 
 RewriteCond $ 1！^（index\.php | images | robots\.txt）
 RewriteCond％{REQUEST_FILENAME}！-f 
 RewriteCond％{REQUEST_FILENAME}！-d 
 RewriteRule ^（。*）$ index.php / $ 1 [L，QSA] 
  

我想要做的是：

访问我的网站前端）与 http://www.mydomain.com/
我的管理员（后端）作为 http://www.mydomain.com/admin/

我不知道为什么这在我的本地服务器上正常工作。

我希望有人可以帮助我。

 UPDATE 

我使用这个工具：

  RewriteEngine on 
 
＃如果用户键入index.php或admin.php。 
 RewriteCond $ 1！^（index\.php | admin\.php | images | robots\.txt）
 
＃如果用户只输入admin。 
 RewriteCond％{REQUEST_FILENAME}！-f 
 RewriteCond％{REQUEST_FILENAME}！-d 
 RewriteRule ^ admin $ admin\.php [L，QSA] 
 
 ＃如果用户输入任何管理部分，如admin / section。 
 RewriteCond％{REQUEST_FILENAME}！-f 
 RewriteCond％{REQUEST_FILENAME}！-d 
 RewriteRule ^ admin\ /(.*)$ admin\.php / $ 1 [L，QSA ] 
 
＃如果用户键入任何网站部分，如site / section。 
 RewriteCond％{REQUEST_FILENAME}！-f 
 RewriteCond％{REQUEST_FILENAME}！-d 
 RewriteRule ^（。*）$ index\.php / $ 1 [L，QSA] $ b $这样我可以访问 
  http://www.mydomain.com/admin 或 http ：//www.mydomain.com/admin/any-section （指向根目录上的admin.php）
 
 
 
我可以访问 http://www.mydomain.com/ 或 http://www.mydomain.com/any-section （指向根目录上的index.php）
 
 
 
感谢您的帮助！
解决方案
首先这是多余的： p> 
 
 
  RewriteCond $ 1！^（index\.php | images | robots\.txt）
  
因为您的其他条件已经处理现有的文件和目录，所以我建议删除它。
 
 
 
您的重写规则是错误的，如果你想/ admin重写到admin.php，与您当前的规则，将导致/index.php/admin。你没有提到是否是问题，如果是这样做：
  RewriteRule ^ / admin $ admin.php [L ，QSA] 
 RewriteRule ^（。*）index.php / $ 1 [L，QSA] 
  
也可以使用RewriteLog调试重写： http：// httpd .apache.org / docs / 2.0 / mod / mod_rewrite.html＃rewritelog  
 
 
 
如果没有解决问题，请说明目前的行为，期望，否则很难帮助。
 
I have a problem with CodeIgniter .htaccess file and hope that somebody can help me!
I don't know regular expressions or how to use the .htaccess, I'm very new with this things!

My Problem is:

I have this structure of files (multi application):
- application
    - admin
    - site
- system
- index.php
- admin.php
And this .htaccess (that works fine on localhost!)
Options +FollowSymLinks
Options -Indexes
DirectoryIndex index.php

RewriteEngine on
RewriteCond $1 !^(index\.php|images|robots\.txt)
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php/$1 [L,QSA]
What I want to do is:

Access my web site (frontend) with http://www.mydomain.com/
And my admin (backend) as http://www.mydomain.com/admin/

I don't know why this works fine on my local server.

I hope someone can help me.  
UPDATE
I got it to work using this:
RewriteEngine on

# If the user types "index.php" or "admin.php".
RewriteCond $1 !^(index\.php|admin\.php|images|robots\.txt)

# If the user types just "admin".
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^admin$ admin\.php [L,QSA]

# If the user enter in any admin section, like "admin/section".
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^admin\/(.*)$ admin\.php/$1 [L,QSA]

# If the user types any site section, like "site/section".
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index\.php/$1 [L,QSA]
This way I can access http://www.mydomain.com/admin or http://www.mydomain.com/admin/any-section (that points to "admin.php" on the root directory)  

And I can access http://www.mydomain.com/ or http://www.mydomain.com/any-section (that points to "index.php" on the root directory)

Thanks for the help!
解决方案
First of all this is redundant:
RewriteCond $1 !^(index\.php|images|robots\.txt)
because your other conditions already take care of existing files and directories so I'd suggest to remove it.

Your rewrite rule is wrong if you want /admin to rewrite to admin.php, with your current rule it will result in /index.php/admin. You didn't mention if that's the problem, if it is do this:
RewriteRule ^/admin$ admin.php [L,QSA]
RewriteRule ^(.*) index.php/$1 [L,QSA]
Also you can debug the rewriting using RewriteLog: http://httpd.apache.org/docs/2.0/mod/mod_rewrite.html#rewritelog

If that doesn't fix it please describe the current behaviour and what you expect, otherwise it's difficult to help.
