Required if

• required_unless()
• Required_unless_rule(array|string $dependetFields, array $dependentValue = [], array $values = [])

Validates the input only if all of the dependent field is equals to the dependent value.

This rule must use the ->checkDependent() method

use AJD_validation\AJD_validation as v;

$v = new v;

$dependent_post_data = ['dependent_field' => 's', 'dependent_field2' => '', 'real_field' => ''];
$dependent_fields = ['dependent_field', 'dependent_field2'];
$dependent_values = ['dependent_field' => 'foo', 'dependent_field2' => 'bar'];

$v->required_unless(
	$dependent_fields, $dependent_values, $dependent_post_data
)
->checkDependent('real_field', $dependent_post_data);  // will not validate because none of the dependent_post_data is equals to the dependent_values.

$v->getValidator()->required_unless(
	$dependent_fields, $dependent_values, $dependent_post_data
)
->validate(''); // false. because none of the dependent_post_data is equals to the dependent_values.
