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

[Richard Reina]

Hi WK,

Thanks for the reply. Line 577 is the print statement  print $key
$input_hash->{ $key } . "\n"; In the foreach. I know I shouldn't be
printing here however, I just want to see what value comes across for for
example $input_hash->{ '13' } before I create a DB record based on that
value.So I guess I just need help figuring out how to see or get the value
out of $input_hash->{ID NUMBER}.
