Answer 1

Use a Standalone Validator.
/**
* #inheritdoc
*/
public function rules()
{
return [
['address', 'validateAddress']
]
}
/**
* Check your address.
*/
public function validateAddress($attribute, $params, $validator)
{
//
// You can access other model fields like so:
// $this->address_type or $this->address or $this->other_field
/* Add your conditions as you see fit.*/
if (strtolower($this->address_type) = 'domestic_address')) {
$this->addError($attribute, 'Address TYPE is too domestic');
}
// or for example
if (strtolower($this->address) = '123 Road-ABC')) {
$this->addError($attribute, 'Address is goofy');
}
}
