Felix Laate	Friday 29 February 2008 12:53:33 am Hi all, I'm tryning to do some subtracting i a template, i.e $lastweek = sub($thisweek,1) This returns a <i>Fatal error: Unsupported operand types</i>. I found out from issues that there is an issue covering this: http://issues.ez.no/6607, which is supposed to be fixed at some time in the future. Now I wonder if someone can think of a workaround?

Pascal Specht	Friday 29 February 2008 3:36:46 am Hi Felix, certainly $lastweek = add($thisweek,-1) won't work much better because $lastweek is probably not an integer... What datatype is $lastweek ? If this is inside a module, you may perhaps get around the problem by calculating the value through the php code and using a template variable to get it back? If $lastweek is a date/time and the operator hasn't been implemented in the template language, you probably will have to write a template operator for this. I always have a small module with useful stuff included in my install, so adding a template operator isn't much work... </Pascal>

Hi all,

I'm tryning to do some subtracting i a template, i.e

$lastweek = sub($thisweek,1)

This returns a <i>Fatal error: Unsupported operand types</i>.

I found out from issues that there is an issue covering this: http://issues.ez.no/6607, which is supposed to be fixed at some time in the future.

Now I wonder if someone can think of a workaround?
