Using cgipm

Joey_learn_Perl has asked for the wisdom of the Perl Monks concerning the following question:

I am having trouble using params. When I use the name of a check box group I only get the first checked value.


print param{'foolist');

`param()` only returns the first value, if used in scalar context. If you want to get all values, try this: `use CGI qw/:standard/; my $first_value = param( 'foolist' ); # only returns the first value my @check_boxes = param( 'foolist' ); # returns all associated values` [download] Of course, be aware that a checkbox will not have any value sent if it's not checked, whereas other input types may send the name in the query string (or entity-body) without an associated value. These behaviors are significantly different and can trip you up if you're not aware of them. I also noticed that you had a curly brace after param, but I assume that's a typo :) Cheers, Ovid Join the Perlmonks Setiathome Group or just click on the the link and check out our stats.

param()

use CGI qw/:standard/;
my $first_value = param( 'foolist' ); # only returns the first value
my @check_boxes = param( 'foolist' ); # returns all associated values
