CakePHP how to assign database connection dynamically - php

Question

I have this constant value called CLIENT_URL
on boostrap:
$clienturl = explode('/', $_SERVER['REQUEST_URI']);
define("CLIENT_URL",$clienturl[2]);
I've debugged and it gets, for example, 'client1', or 'client2', etc.
I need to use that value when defining a configuration array, such as:
on database.php
class DATABASE_CONFIG {
var $default = array(
'datasource' => 'Database/Mysql',
'persistent' => false,
'host' => 'localhost',
'login' => '*****',
'password' => '****',
'database' => 'client3',
'prefix' => ''
);
var $clientdb = array(
'datasource' => 'Database/Mysql',
'persistent' => false,
'host' => 'localhost',
'login' => '****',
'password' => '****',
'database' => 'client3',
'prefix' => ''
);
public function __construct() {
debug('constant value: '.CLIENT_URL);
debug($this->default['database']);
$this->default['database'] = CLIENT_URL; // This line does nothing !!
//$this->clientdb['database'] = CLIENT_URL; // This lines prevent connection, error: Database connection "Mysql" is missing, or could not be created !!
$this->default = $this->clientdb;
debug($this->default['database']);
}
};
However, database remains unchanged, it keeps initial value from above.
Actually i can do:
$this->default['database'] = 'whatever';
and it won't even try to find 'whatever' database; it seems this assignment is missing some reload or something?
After the assignment on __construct,
I've debugged
debug($this->default['database']);
Before and after the assignment and it does not change.
It only changes doing this:
$this->clientdb['database'] = CLIENT_URL; // Instead of $this->default['database'] = CLIENT_URL;
But then connection fails.
Please note the app does connect to the database given at the very beginning ('client3'), it just don't switch.
I check database via a find, that always return same record from same database, no switch.
$options = array('conditions' => array('User.id' => 1));
$clientArray = $this->User->find('first', $options);
Thank you for any pointers.

You need to do like this
class DATABASE_CONFIG {
var $client1db = array(
'datasource' => 'Database/Mysql',
'persistent' => false,
'host' => 'localhost',
'login' => '*****',
'password' => '*****',
'database' => 'client1',
'prefix' => ''
);
public function __construct() {
$this->default = $this->clientdb;
$this->default['database'] = CLIENT_URL;
}
};
