Question

Quoted from here:

my $result = FormValidator::Simple->check( $query => [
    param1 => ['NOT_BLANK', 'ASCII', ['LENGTH', 2, 5]],
    param2 => ['NOT_BLANK', 'INT'  ],
    mail1  => ['NOT_BLANK', 'EMAIL_LOOSE'],
    mail2  => ['NOT_BLANK', 'EMAIL_LOOSE'],
    { mails => ['mail1', 'mail2'       ] } => ['DUPLICATION'],
    { date  => ['year',  'month', 'day'] } => ['DATE'],
] );

IMO it should be :

my $result = FormValidator::Simple->check( $query => {
    ...
} );

Why does FormValidator::Simple prefer array to hash?

Answer 1

Are you suggesting you should be able to use

my $result = FormValidator::Simple->check( $query => {
    param1 => ['NOT_BLANK', 'ASCII', ['LENGTH', 2, 5]],
    param2 => ['NOT_BLANK', 'INT'  ],
    mail1  => ['NOT_BLANK', 'EMAIL_LOOSE'],
    mail2  => ['NOT_BLANK', 'EMAIL_LOOSE'],
    { mails => ['mail1', 'mail2'       ] } => ['DUPLICATION'],
    { date  => ['year',  'month', 'day'] } => ['DATE'],
} );

That would pass the following

{
    param1 => ['NOT_BLANK', 'ASCII', ['LENGTH', 2, 5]],
    param2 => ['NOT_BLANK', 'INT'  ],
    mail1  => ['NOT_BLANK', 'EMAIL_LOOSE'],
    mail2  => ['NOT_BLANK', 'EMAIL_LOOSE'],
    'HASH(0x2aaffc)' => ['DUPLICATION'],
    'HASH(0x32aff4)' => ['DATE'],
}

There’s lots of information missing.
