Load database value with function - php

Question

I didn't see any topic like this so I posted a new one.
First of all, I'm sorry about my bad English.
I want an public function who can storage in a global variable a value from database, and with that value the php script select the website templates. Can you help me?
private $page_title = null;
private $body_title = null;
private $body_content = null;
private $template = null;
private $settings = array();
private $file_template = 'content';
private $path = 'templates/';
private $parse_page = false;
global $template2;
public function GetHASH()
{
return $this->hash;
}
function Tema()
{
global $db,$user_class;
if($user_class->authorized)
{
$row = $db->sql("SELECT * FROM `ucp_users` WHERE `user_hash` = '".$this->GetHASH()."'");
$array = $db->get_array($row);
$template2 = $array['template'];
}
else
{
$template2 = '1';
}
return $template2;
}
function __construct() {
switch($template2) {
default:
{
$template_name = 'dsa/';
$template2 = 1;
}
break;
case 0: $template_name = 'lsrp/';
break;
case 1: $template_name = 'dsa/';
break;
}
$this->path = $this->path.''.$template_name;
}
Thank you.

When you instantiate your class, the constructor is called, at this time your tema method has not been invoked yet since it cannot be called without an instance. One solution would be to call your tema method in your constructor like this :
function __construct() {
$template2 = this->tema();
switch($template2) {
default:
{
$template_name = 'dsa/';
$template2 = 1;
}
break;
case 0: $template_name = 'lsrp/';
break;
case 1: $template_name = 'dsa/';
break;
}
$this->path = $this->path.''.$template_name;
}
