How to print the variables of an array as checkbox

问题:

Is there a simple way to print check boxes in an cgi form whose names are variables of an array?

回答1:

You have several problems.

1. If you want to pass multiple values to a single property in a hash, then you need to pass a reference. Your code (before you deleted it from the question during the grace period when edits are not recorded) will be interpreted as: checkbox("-values" -> "apple", "orange" => "berry").
2. checkbox only takes one value. If you want to pass multiple, then you need to call it multiple times
3. CGI.pm's HTML generation functions should no longer be used. Switch to a template system instead.

For example:

#!/usr/bin/env perl

use v5.10;
use strict;
use warnings;

use Template;

my @checkbox_values = qw[apple orange berry];
my $template = q[
    Example template
    [% FOR item IN checkbox_values %]
    <input type="checkbox" name="example" value="[% item | html %]">
    [%- END %]
];

print Template->new()->process(\$template, { checkbox_values => \@checkbox_values })

NB: Templates are better stored in separate files.
