My understanding is that you use || because it's more tightly bound than
'or'. Although I would suggest something further for this:
my $action
= defined( param('form_action') )
? param('form_action')
: 'default_value'
;
This way if zero is a valid value for the form_action parameter it will
still pass through. Depends how you're doing things really.
Further, Data::FormValidator might be of interest in the future.
