Host config broke my code, please help.

[Tarantulus]

Hi Guys/Girls,

I have been coding a website for a friend, everything worked fine on my localhost setup, then I FTP to their host and now it's broken....

the error is

Fatal error: Unknown(): The script tried to execute a method or access a property of an incomplete object. Please ensure that the class definition cart of the object you are trying to operate on was loaded _before_ the session was started in /index.php on line 40

line 40 of index.php is

$cart -> add($id,$qty,$price);

and the necessary function is

function add($prod_id,$qty,$price) {
		
		
			session_start();
			
		
			if (isset ($_SESSION['cart'][$prod_id])){
				$_SESSION['cart'][$prod_id]['qty'] += $qty;
			} 
			else{
				$_SESSION['cart'][$prod_id] = array("qty"=>$qty,"price"=>$price);
				
			}
		
		
	}

can someone point out what I've done wrong??

Heya, Tarantulus.

'Incomplete Class' generally refers to a PHP-4-style class on a PHP 5 installation. Check your phpinfo() output and verify your friend's PHP version.

funnily enough I have PHP 5.x and the host has 4.x AND 5.x but runs 4.x as default, which is where I first saw the error. this error comes up since I changed the .htaccess to use 5.x.

I just realised this post makes it sound like the problem was solved.

I should say that it is broken in both PHP4 and PHP5, however the specific error I mentioned is with PHP5.

it's driving me insane as it works on my PHP5 install without a hitch!

According to this comment:

You get this error if you have and object in your $_SESSION array and you call session_start() before you have loaded your included classes.

Try implementing an autoloader.

thanks for the pointers, turns out there was no problem with my code though... re-uploaded and it worked.

thanks again
