[dancer-users] Trapping parameters from a dynamic list of checkboxes.

[Richard Reina]

That worked! Thank you very much.

Interestingly though $input_hash->{ $key } appears as a hash ref
"HASH(0xa1d2344)" which I was not able to dereference with
%$input_hash->{key}.  This doesn't bother me much because all I really need
to know is that it has value -- that tells me the user checked the box for
this option.

So, instead of looking at the actual value I was just going to do:

    # get parameter for accomp type keys
      foreach my $key ( keys %$Accomps ) {

      if ( param( $key ) ) { # paramter has value
          $input_hash->{ $key } = $Accomps->{ $key };

          # user checked this box. Enter a record into TO_DO table

      }
      }

Is that okay? Or would such an un-exact way of doing it have a downside?
