Connection with multiple databases.

[eluser]Unknown[/eluser]
I'm having trouble connecting to multiple databases.
A controller requesting 4 models, each of these models use a different database.

Code controller making the call to the models

Code:

if($this->input->post('database1'))
{
    $this->load->model("systems/Database1_Model","database1Model");
    $this->database1Model->insertUser($name,$email,$login,$pass);
    $this->model->updateAccessSystem($userId,$this->input->post('database1'),true);                      
}

if($this->input->post('database2'))
{
    $this->load->model("systems/Database2_Model","database2Model");
    $this->database2Model->insertUser($name,$email,$login,$pass);  
    $this->model->updateAccessSystem($userId,$this->input->post('database2'),true);                  
}

if($this->input->post('database3'))
{
    $this->load->model("systems/Database3_Model","database3Model");
    $this->database3Model->insertUser($name,$email,$login,$pass);  
    $this->model->updateAccessSystem($userId,$this->input->post('database3'),true);                  
}

if($this->input->post('database4'))
{
    $this->load->model("systems/Database4_Model","database4Model");
    $this->database4Model->insertUser($name,$email,$login,$pass);  
    $this->model->updateAccessSystem($userId,$this->input->post('database4'),true);                
}

Code example of one of the models dynamic connections

Code:

/**
    * Insert user
    *
    * @access public
    * @since Wed Aug 13 16:15:37 BRT 2008
    * @param String $name Name of person.
    * @param String $email Email of e-mail.
    * @param String $login Login of user.
    * @param String $pass Password of user.
    * @return void
    */
    function insertUser($name,$email,$login,$pass)
    {
        // Closing default connection
        $this->db->close();
        // Load config of new config database access    
    $config['hostname'] = "localhost";
    $config['username'] = "root";
    $config['password'] = "123";
    $config['database'] = "mydatabase1";
    $config['dbdriver'] = "mysql";    
    $config['dbprefix'] = "";
    $config['pconnect'] = FALSE;
    $config['db_debug'] = TRUE;
    $config['cache_on'] = FALSE;
    $config['cachedir'] = "";
    $config['char_set'] = "utf8";
    $config['dbcollat'] = "utf8_general_ci";
        $access = $this -> load -> database($config , TRUE);
        //check exists
        $data = array('login'=>$login);[/pre]
        [b]$rs = $access -> get_where('admin', $data)->result_array();[/b][pre]
        if(sizeof($rs)==0)
        {
            // Populating line
            $data['login'] = $login;
            $data['password'] = md5($pass);
            $data['name'] = $name;
            $data['email'] = $email;          
            $access-> insert('admin', $data);
        }else
        {
            $access->update('admin',array('password' => md5($pass)),array('login'=>$login));    
        }
        // Closing connection
        $this-> db -> close();
        $access -> close();
        $this->load->database('default');
    }

Code of model that uses the default connection

Code:

/**
    * Insert access user of a outer system.
    *
    * @access public
    * @since Fri Aug 22 10:48:27 BRT 2008
    * @param String $userId Id of user.
    * @param String $systemId Id of system.
    * @return void
    */
    function updateAccessSystem($userId,$systemId,$value=true)
    {      
        if($value)
        {
            $data = array('id_sys_FK'=>$systemId,'id_user_FK'=>$userId);
            $rs = $this->db->get_where('auto_user_sys', $data)->result_array();
            if(sizeof($rs)==0)
            {
                $this->db->insert('auto_user_sys',$data);
            }            
        }else
        {            
            $where = array('id_sys_FK'=>$systemId,'id_user_FK'=>$userId);
                $this->db->delete('auto_user_sys',$where);
        }        
    }

I am opening and closing the connections right??
Thanks,
