Hi, I'm using smarty in x-cart. I've created a variable called $newsubtotal in a template called cart_subtotal.tpl.

I want to pass just the variable $newsubtotal to another template called cart.tpl.

I tried using {include file='modules/Fast_Lane_Checkout/cart_subtotal.tpl' newsubtotal1=$newsubtotal} but it included the whole template not just the variable $newsubtotal.

Any help would be greatly appreciated.

Thanks!

child templates inherit all the variables of the parent. If you pass a specific variable as a parameter, it is additive to the existing variables.

Thanks for your quick reply. Unfortunately, I still don't quite understand..

if I assign a variable in the parent template,

{assign var="newsubtotal1" value="0.00"}

and a variable in the child template
called $newsubtotal = 250.

how do I call this variable back into the parent template? I assumed I can call it using the include function, but my format must be wrong because it includes the entire template {include file='modules/Fast_Lane_Checkout/cart_subtotal.tpl' newsubtotal1=$newsubtotal} ??

Thanks Monte! Worked like a champ. Why is it a "hack" ? Will it cause any issues in certain situations?

Thanks again

Its a hack in the sense that variables are not available to parent templates normally. But you can get them there with capture, even though capture wasn't meant for this. It won't break anything.
