Hi Melbourne PM,
I'm getting a bit of a headache the following problem. Hope someone can
help.
Template toolkit, in most instances, will treat a scalar as an
arrayref of 1 element, if you treat it as an array.
This doesn't work, however, if your scalar value is 0.
Is there any way of checking if a variable contains a reference?
What I want to be able to do is something like this:
unless(ref($array) eq 'ARRAY'){
$array = [$array];
}
...but in a template. Or maybe there's a much better way?
Thanks
crash
