List Data in TT and CGI

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

Hello monks,

I am not able to correctly process a list of error fields returned from my form validator. Even if three fields fail the required validation, only 1 field eg- s_tel is getting printed in the markup. The results from FormValidator are accurate and all three fields are getting retrieved.(confirmed with logging statements)
any advice would be great !

TT code in template file

[% IF error_list %]

    [% FOREACH i IN error_list %]
    [% i %] |
    [% END %]

[% END %]

Code in CGI_Application module

        my $input_profile = {
           required => [qw( s_addr s_tel s_adv01)]
        };
    my $results = Data::FormValidator->check(\%validation_params,$inpu
+t_profile);
    my %ret_params = ( 'error_list' => $results->missing);
    
    if($results->has_invalid or $results->has_missing){
        return $self->tt_process('school_register.tt',\%ret_params);
    }

The context is wrong when assigning your return params hash. Think the following should fix it up: `my %ret_params = ( 'error_list' => scalar $results->missing );` [download] The relevant documentation: Missing says you need scalar context to get a reference to the array of missing fields.
