php - CakePHP how to assign database connection dynamically -

i have constant value called client_url

on boostrap:

$clienturl = explode('/', $_server['request_uri']); define("client_url",$clienturl[2]); 

i've debugged , gets, example, 'client1', or 'client2', etc. need use value when defining 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']);      $this->default['database'] = client_url; // line nothing !!     //$this->clientdb['database'] = client_url; // lines prevent connection, error: database connection "mysql" missing, or not created !!     $this->default = $this->clientdb;     debug($this->default['database']);   } }; 

however, database remains unchanged, keeps initial value above. can do:

$this->default['database'] = 'whatever'; 

and won't try find 'whatever' database; seems assignment missing reload or something?

after assignment on __construct,

i've debugged

debug($this->default['database']);  

before , after assignment , not change. changes doing this:

$this->clientdb['database'] = client_url; // instead of $this->default['database'] = client_url; 

but connection fails.

please note app connect database given @ beginning ('client3'), don't switch. check database via find, return same record same database, no switch.

$options = array('conditions' => array('user.id' => 1)); $clientarray = $this->user->find('first', $options); 

thank pointers.

you need

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; }  };
