METHODS ^

Mojolicious::Validator::Validation inherits all methods from Mojo::Base and implements the following new ones.

check

  $validation = $validation->check('size', 2, 7);

Perform validation check on all values of the current "topic", no more checks will be performed on them after the first one failed.

csrf_protect

  $validation = $validation->csrf_protect;

Validate csrf_token and protect from cross-site request forgery.

error

  my @names   = $validation->error;
  my $err     = $validation->error('foo');
  $validation = $validation->error(foo => ['custom_check']);

Get or set details for failed validation check, at any given time there can only be one per field.

  my ($check, $result, @args) = @{$validation->error('foo')};

has_data

  my $bool = $validation->has_data;

Check if "input" is available for validation.

has_error

  my $bool = $validation->has_error;
  my $bool = $validation->has_error('foo');

Check if validation resulted in errors, defaults to checking all fields.

is_valid

  my $bool = $validation->is_valid;
  my $bool = $validation->is_valid('foo');

Check if validation was successful and field has a value, defaults to checking the current "topic".

optional

  $validation = $validation->optional('foo');

Change validation "topic".

param

  my @names       = $validation->param;
  my $foo         = $validation->param('foo');
  my @foo         = $validation->param('foo');
  my ($foo, $bar) = $validation->param(['foo', 'bar']);

Access validated parameters, similar to "param" in Mojolicious::Controller.

required

  $validation = $validation->required('foo');

Change validation "topic" and make sure a value is present and not an empty string.

AUTOLOAD ^

In addition to the "ATTRIBUTES" and "METHODS" above, you can also call validation checks provided by "validator" on Mojolicious::Validator::Validation objects, similar to "check".

  $validation->required('foo')->size(2, 5)->like(qr/^[A-Z]/);
  $validation->optional('bar')->equal_to('foo');
  $validation->optional('baz')->in(qw(test 123));
