网址重写导致Magento管理员无法访问

I have magento in a subdirectory in the root and if I set the secure base url and secure base url link to the correct shared ssl url to enable secure pages I have no problem in the FRONTEND. The pages displays as they should. However when I try to access the admin with the secure link below I cannot gain admittance.

For instance in the frontend: http://mydomain.com/shop becomes http://mydomain.com - which is correct.

https://mydomain.sharedssl.com/shop/customer/account/login/ becomes https://mydomain.sharedssl.com/customer/account/login/ - which is correct.

But then I can access admin with neither https://mydomain.com/shop/index.php/admin/ nor https://mydomain.com//index.php/admin/

In the root directory I have this in my htaccess:

RewriteEngine On
RewriteBase /
RewriteCond %{REQUEST_URI} !^/shop(.*)
RewriteRule (.*) /shop/$1 [L]

and in the shop (Magento) I have the following:

Could someone lend some assistance to getting this to work in the Magento backend?

The problem is in getting of REQUEST_URI environment variable value and checking it with SCRIPT_FILENAME and SCRIPT_NAME environment variables values. In your case REQUEST_URI is /index.php/stddadmin/ and SCRIPT_FILENAME with SCRIPT_NAME are equals to /shop/index.php and Magento unable to retrieve path info for controllers matching. So a cause of the problem is in adding of /index.php/ prefix to the request path and the Magento url generation has this value hardcoded for admin.

There are only two solutions to your problem:

  1. Override method called _updatePathUseRewrites in Mage_Core_Model_Store model like in the following example:

     class Your_CustomModule_Model_Store extends Mage_Core_Model_Store 
     {
         protected _updatePathUseRewrites($url) 
         {
             return $url; // Return passed variable without adding index.php as prefix 
         }
     }
    

    In this case your admin panel will be available at /admin/ url, like usual frontend page.

  2. Reorganize project structure for placing Magento in root folder or add symbolic links on each its file and folder in root.

You can also use the "Admin Rewrites" extension to get rid of "index.php" in backend URLs: http://www.magentocommerce.com/magento-connect/clockworkgeek/extension/3692/clockworkgeek_adminrewrites

It enables URL rewrites in the backend and it works fine. The only con is that it is marked as "Beta", because it overrides "Mage_Core_Model_Store".
