Magento multi website controller

Is it possible to programmatically dispatch websites in Magento? Currently, I have a directory in the root of my site called /websites. In this directory I have subdirectories for each website, for example, site_a, site_b, site_c. Then each site subdirectory has a .h开发者_如何转开发taccess and index.php with appropriate run code, for example:

$mageFilename = '../../app/Mage.php';
require_once $mageFilename;    
Mage::run("site_b", "website");

in the index.php in /websites/site_b. While this works, I do wish to avoid doing file management in the filesystem. Anyone can give any recommendation on the best way to do this? Perhaps a script in /websites that stands in place of the individual site sub directories. Any help appreciated.

You have access to the $_SERVER variables in php and you can use these to determine the Mage::run("whatever", "website"); call, e.g.:

$whatever=$_SERVER['condition/url/whatever'];

// or use some cookies 

if (isset($_COOKIE['dev'])) $whatever=$_COOKIE['dev'];


switch($whatever)
{ case "example.com":
  case "www.example.com":
    $_SERVER['MAGE_RUN_CODE'] = "example";
    $_SERVER['MAGE_RUN_TYPE'] = "website";
    break;
  case "dev":
  case "test.com":
    $_SERVER['MAGE_RUN_CODE'] = "test";
    $_SERVER['MAGE_RUN_TYPE'] = "website";
  default:
    $_SERVER['MAGE_RUN_CODE'] = "live";
    $_SERVER['MAGE_RUN_TYPE'] = "website";
}
Mage::run($_SERVER['MAGE_RUN_CODE'], $_SERVER['MAGE_RUN_TYPE']);

In this way you only need one code base plus correctly configured settings in Magento backend to route to your different stores.

You can handle all in .htaccess file mine looks like this:

#SetEnvIf Host www\.lenjerii\.com MAGE_RUN_CODE=base
#SetEnvIf Host www\.lenjerii\.com MAGE_RUN_TYPE=website
#SetEnvIf Host ^lenjerii\.com MAGE_RUN_CODE=base
#SetEnvIf Host ^lenjerii\.com MAGE_RUN_TYPE=website

#SetEnvIf Host www\.wildfashion\.ro MAGE_RUN_CODE=wildfashion
#SetEnvIf Host www\.wildfashion\.ro MAGE_RUN_TYPE=website
#SetEnvIf Host ^wildfashion\.ro MAGE_RUN_CODE=wildfashion
#SetEnvIf Host ^wildfashion\.ro MAGE_RUN_TYPE=website

This solution eliminate any other folders for your additional websites.

if I understand you correctly, what you need are some symbolic link: in each subdirectory, make symbolic link to the original installation. IE: ln -s ../app/ ./app.
