Subject: How to ck for null set w/ Checkboxes
> How do y
How do you check for the null set or blank with checkboxes using
CGI.pm? The following code does not work for checkboxes though it
does for all other input fields.
#TEST FOR BAD CHARS
my ($name, $value);
foreach $name ($q->param())
{foreach $value ($q->param( $name ))
{#CK FOR BLANKS
if
