Change default index.php when using admin route

Question

I'm currently on a project which gave me a small headache after trying to find a solution for a tiny problem I've bumped onto.

At the moment, my application loads my index.php file on every single page request it gets. Inside my index, the application fires-up some basic stuff, sets some variables etc. Well, the thing I'm currently looking for is that I would like to let my server load a different file (for example admin.php) as default. But, this only needs to happen when the url sub-directory is set as http://www.mydomain.com/admin/

So the server needs to handle every little thing exactly the same, but when the route is set as /admin/, its needs to autoload the admin.php instead of the default index.php.

Currently my .htaccess file looks like this

# mod-rewrite engine
RewriteEngine On

RewriteCond %{REQUEST_FILENAME} -s [OR]
RewriteCond %{REQUEST_FILENAME} -l [OR]
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule ^.*$ - [NC,L]
RewriteRule ^.*$ index.php [NC,L]

EDIT: To clear things up and visualize it a bit more:

• http://www.mydomain.com/users/me/logs/ -> index.php

• http://www.mydomain.com/admin/users/me/logs/ -> admin.php

• http://www.mydomain.com/admin/stackoverflow/questions -> admin.php - http://www.mydomain.com/stackoverflow/questions -> index.php

Inside these two file I load a new Zend_Application (ZF1)

Answer 1

Have you tried with the following RewriteRule:

RewriteRule ^admin/?$ admin.php [L]

Your .htaccess would look likes:

# mod-rewrite engine
RewriteEngine On

RewriteCond %{REQUEST_FILENAME} -s [OR]
RewriteCond %{REQUEST_FILENAME} -l [OR]
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule ^admin/?$ admin.php [L]
RewriteRule ^.*$ - [NC,L]
RewriteRule ^.*$ index.php [NC,L]

Update 1

and if you try the RewriteRules in the following order:

RewriteRule ^.*$ - [NC,L]
RewriteRule ^.*(admin).*$ admin.php [NC,L]
RewriteRule ^.*$ index.php [NC,L]

Answer 2

This should do the trick:

RewriteEngine On

# handle requests to /admin/
RewriteCond %{REQUEST_FILENAME} -s [OR]
RewriteCond %{REQUEST_FILENAME} -l [OR]
RewriteCond %{REQUEST_FILENAME} -d
RewriteCond %{REQUEST_URI} ^/admin/$
RewriteRule ^.*$ admin.php [NC,L]

# handle all other requests
RewriteCond %{REQUEST_FILENAME} -s [OR]
RewriteCond %{REQUEST_FILENAME} -l [OR]
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule ^.*$ - [NC,L]
RewriteRule ^.*$ index.php [NC,L]

Answer 3

To un-complicate things, you could have used a common boostrap script which would conditionally include the files. For example:

RewriteCond %{REQUEST_FILENAME} -s [OR]
RewriteCond %{REQUEST_FILENAME} -l [OR]
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule ^.*$ - [NC,L]
RewriteRule ^.*$ bootstrap.php [NC,L]

Then, in bootstrap.php

<?php

if(USER_IS_ADMIN){
  require('admin.php');
}else{
  require('index.php');
}
