cakephp dynamic db connection - cakephp

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

Answer 1

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.

Ah I got it now,
I thought DATABASE_CONFIG was called statically so didn't think to use the construct.
www.domain.com/12345678
function __construct() {
// get folder
if(substr(php_sapi_name(), 0, 3) == "cli") {
$j = explode("/", $_SERVER['PWD']);
$this->default['database'] = "sa_".$j[count($j)-1];
} else {
$j = explode("/", $_SERVER['REQUEST_URI']);
$this->default['database'] = "sa_".$j[1];
}
}
but commandline bake must be done in folder eg. 12345678/
