$_SESSION['cart']->total += addedAmount not showing up in $cartShowTotal

[tcarden]

Hey Everyone,
it's Mr. HazMat here again...

i'm trying to add a HazMat fee (using a Session variable) to the cart total
like so....

$_SESSION['cart']->total += $_SESSION['hazMatFee']; 

i've echoed out the 2 variables:

$_SESSION['cart']->total and $_SESSION['hazMatFee'];

on the tpl_shopping_cart_default.php and they seem correct.

but the $cartShowTotal is not reflecting the added fee.
and subsequent checkout pages are not showing it either.

can someone advise on how to get this to be added to the total?

btw - in the class constuctor method i'm using
'NOTIFIER_CART_SHOW_TOTAL_END'

You can't add amounts to the shopping cart without adding them as line items, otherwise they won't get calculated properly when the line-items are summed.

Or, use an Order Total module to add the amount to the order during checkout.

thanks, what is a 'line item'?

and for Order Total module, you mean one that already exists?,

Well, in the strictest sense, it's a product.
So, unless you're adding another "product" to the cart, that's not what you want to bother doing.

and for Order Total module, you mean one that already exists?,

No. I envision that your whole thing needs to ultimately manifest as an order-total entry, which means building an order-total module to read all the other data you've generated elsewhere, and then output it during checkout.

ok, thanks

I really don't know how to do an order total module YET, but for the time being.
i'd like to just do a hack, i'm way behind on this as is!

i'm doing well with these Hazmat session vars and would like to do this, (pseudo code

if(isset($_SESSION['hazMatFee'])) {
$shoppingCartTotal += $_SESSION['hazMatFee']; }

can you tell which file i could add that to? i've been poking around but haven't found it so far

[DrByte]

Try this:

[tcarden]

ok, definitely i will.

thanks!

[tcarden]

a huge belated thanks Dr. Byte!, i really appreciate you taking the time to create that code.

i installed but is not working. i believe the ot_hazmatfee.php is not loading.

though i put it here.....
includes/modules/order_total/

to test i changed function __construct() to function __xconstruct, but there were no errors.

to troubleshoot, i tried renaming same as the ObserverNotifier class i created hazMatProduct (ot_hazMatProduct.php) but that didn't seem to make it load either.

how can i get this to load?,

thanks

[tcarden]

btw - i looked through the code, and am sure the variable

$_SESSION['hazMatFee'] is set as i've been echoing it out in tpl_shopping_cart_default.php
