NAME
FormValidator::Simple::Results - results of validation

SYNOPSIS
    my $results = FormValidator::Simple->check( $req => [
        name  => [qw/NOT_BLANK ASCII/, [qw/LENGTH 0 10/] ],
        email => [qw/NOT_BLANK EMAIL_LOOSE/, [qw/LENGTH 0 30/] ],
    ] );

    if ( $results->has_error ) {
        foreach my $key ( @{ $results->error() } ) {
            foreach my $type ( @{ $results->erorr($key) } ) {
                print "invalid: $key - $type \n";
            }
        }
    }

DESCRIPTION
This is for handling resuls of FormValidator::Simple's check.

This object behaves like Data::FormValidator's results object, but has some specific methods.

CHECK RESULT

has_missing
    If there are missing values ( failed in validation 'NOT_BLANK' ), this method returns true.

        if ( $results->has_missing ) {
            ...
        }

has_invalid
    If there are invalid values ( failed in some validations except 'NOT_BLANK' ), this method returns true.

        if ( $results->has_invalid ) {
            ...
        }

has_error
    If there are missing or invalid values, this method returns true.

        if ( $results->has_error ) {
            ...
        }

success
    inverse of has_error

        unless ( $resuls->success ) {
            ...
        }

ANALYZING RESULTS

  missing

no argument
    When you call this method with no argument, it returns keys failed 'NOT_BLANK' validation.

        my $missings = $results->missing;
        foreach my $missing_data ( @$missings ) {
            print $missing_data, "\n";
        }
        # -- print out, for example --
        # name
        # email

key When you call this method with key-name, it returnes true if the value of the key is missing.

        if ( $results->missing('name') ) {
            print "name is empty! \n";
        }

  invalid

no argument
    When you call this method with no argument, it returns keys that failed some validation except 'NOT_BLANK'.

        my $invalids = $results->invalid;
        foreach my $invalid_data ( @$invalids ) {
            print $invalid_data, "\n";
        }
        # -- print out, for example --
        # name
        # email

key When you call this method with key-name, it returns names of failed validation.

        my $failed_validations = $results->invalid('name');
        foreach my $validation ( @$failed_validations ) {
            print $validation, "\n";
        }
        # -- print out, for example --
        # ASCII
        # LENGTH

key and validation-name
    When you call this method with key-name, it returns false if the value has passed the validation.

        if ( $results->invalid( name => 'LENGTH' ) ) {
            print "name is wrong length! \n";
        }

  error
This doesn't distinguish 'missing' and 'invalid'. You can use this like 'invalid' method, but this consider 'NOT_BLANK' same as other validations.

    my $error_keys = $results->error;

    my $failed_validation = $resuls->error('name');
    # this includes 'NOT_BLANK'

    if ( $results->error( name => 'NOT_BLANK' ) ) {
        print "name is missing! \n";
    }

    if ( $results->error( name => 'ASCII' ) ) {
        print "name should be ascii code! \n";
    }
