porblem with template and IF statement

[AndreF]

I have a templating system which is OO. It works fine. but when I want to pass some variables to the template file I do use:
$body->set('blah', $blah);

and when I do print $blah in template file it has correct value so I am sure the value is passed fine, but when I use that in an 'IF statement' in template file like:

if (!empty($blah)) {
// do something
}

it doesn't go to that if stastement.
any idea what is the problem?

I don't fully understand where you're placing that if() statement... is it inside of the class? If so, you might need to do something like $this->blah instead of $blah.

EDIT: Now that I read the post, actually, it might be a scope issue instead or something else. We'd need to see more code in order to understand your problem.
