PHP static objects giving a fatal error
- by Webbo
I have the following PHP code;
<?php
component_customer_init();
component_customer_go();
function component_customer_init()
{
$customer = Customer::getInstance();
$customer->set(1);
}
function component_customer_go()
{
$customer = Customer::getInstance();
$customer->get();
}
class Customer
{
public $id;
static $class = false;
static function getInstance()
{
if(self::$class == false)
{
self::$class = new Customer;
}
else
{
return self::$class;
}
}
public function set($id)
{
$this->id = $id;
}
public function get()
{
print $this->id;
}
}
?>
I get the following error;
Fatal error: Call to a member function
set() on a non-object in
....../classes/customer.php on line 9
Can anyone tell me why I get this error? I know this code might look strange, but it's based on a component system that I'm writing for a CMS. The aim is to be able to replace HTML tags in the template e.g.;
<!-- component:customer-login -->
with;
<?php component_customer_login(); ?>
I also need to call pre-render methods of the "Customer" class to validate forms before output is made etc.
If anyone can think of a better way, please let me know but in the first instance, I'd like to know why I get the "Fatal error" mentioned above.
Cheers
