Question

I have an application where each subscriber gets their own ‘app’ folder within their own url eg.

www.domain.com/1234 subscriber1
www.domain.com/2345 subscriber2

now the db connection is configured in a class in config/database.php. I want to be able to change the database used based on the url (eg. /1234 = db_1234).

How would I achieve this?

Thanks

BTW I am using CakePHP 2.0

My previous solution was a load of rubbish. So I thought about attacking the problem from a different angle. My DATABASE_CONFIG class (/app/Config/database.php) now looks like this:

class DATABASE_CONFIG {

  public $default = array(
    'datasource' => 'Database/Mysql',
    'persistent' => false,
    'host' => '127.0.0.1',
    'login' => 'xxxx',
    'password' => 'xxxx',
    'database' => 'xxxx',
    'prefix' => '',
    'encoding' => 'utf8',
  );

  public $site_one = array(
    'datasource' => 'Database/Mysql',
    'host' => '127.0.0.1',
    // ...  
  );

  public $site_two = array(
    'datasource' => 'Database/Mysql',
    'host' => '127.0.0.1',
    // ...
  );

  public function __construct()
  {
    if (strpos(env('HTTP_HOST'), 'site_one') !== false) {      

      // use site_one database config
      $this->default = $this->site_one;

    // elseif site_two
    } elseif (strpos(env('HTTP_HOST'), 'site_two') !== false) {

      // use site_two database config
      $this->default = $this->site_two;
    }
  }

}

When Cake loads, the construct is now called automatically, and this sets the ‘default’ database connection dependent on the host.
