NAME

       HTML::Widget::Constraint::CallbackOnce - CallbackOnce Constraint

SYNOPSIS

	   my $c = $widget->constraint( 'CallbackOnce', 'foo', 'bar' )->callback(
	     sub {
	       my ($foo, $bar) = @_;
	       return 1 if $foo == $bar * 2;
	   });

DESCRIPTION

       A callback constraint which will only be run once for each call of "process" in HTML::Widget.

METHODS

   callback
   cb
       Arguments: &callback

       Requires a subroutine reference used for validation, which will be passed a list of values corresponding to the constraint names.

       "cb" is provided as an alias to "callback".

   process
       Overrides "process" in HTML::Widget::Constraint to ensure "validate" is only called once for each call of "validate".

   render_errors
       Arguments: @names

       A list of element names for which an error should be displayed.

       If this is not set, the default behaviour is for the error to be displayed for all of the Constraint's named elements.

   validate
       perform the actual validation.

NAME

       HTML::FormFu::Constraint::_others - Base class for constraints needing others() method

METHODS

   others
       Arguments: @nested_names

   other_siblings
       Arguments: $bool

       If true, the "others" list will be automatically generated from the "nested_name" of all fields which are considered siblings of the field
       the constraint is attached to.

       Sibling are found by searching up through the field's parental hierarchy for the first block containing any other field. All fields
       attached at any depth to this block are considered siblings.

   attach_errors_to_base
       If true, any error will cause the error message to be associated with the field the constraint is attached to.

       Can be use in conjunction with "attach_errors_to_others".

       Is ignored if "attach_errors_to" is set.

   attach_errors_to_others
       If true, any error will cause the error message to be associated with every field named in "others".

       Can be use in conjunction with "attach_errors_to_base".

       Is ignored if "attach_errors_to" is set.

   attach_errors_to
       Arguments: @field_names

       Any error will cause the error message to be associated with every field named in "attach_errors_to".

       Overrides "attach_errors_to_base" and "attach_errors_to_others".
