Accessing delivery state name for customization

Hi:

I am adding a test for delivery state in zones.php. I am using the following statement $state = $order->delivery['state']; after setting global $db; Is it correct? Is there a place where developers can look for correct syntax and access of zen cart variables?

It depends on what you want to get and where in the code you are when you want to get it ...

$state = $order->delivery['state'];

says you want to access the order class and get the delivery state, but that is not accessing the database where you need access to the $db ... you need access to the $order so the global would be on that:
global $order;
$state = $order->delivery['state'];

and providing the $order exists where you are testing for this, then it would be available ...

You can always add a var_dump of the array, such as:
global $order;
echo var_dump($order);

to see the content to know if the data is available within the function you are trying to add this test ...

Thanks. I was using it in zones.php. I added global $db; after global $cart; Since it worked I can retest after removing global $db; Thanks again
