Hello,
I know, regarding the subject do you think... please not more of these
questions but I have searched the web for hours and days now and I couldn't
find the answer on my specific question. Let me explain my current
situation:
1. I have a Form-Class called OrderForm that extends Zend\Form\Form:
class OrderForm extends Form
{
public function __construct()
{
parent::__construct('order');
//-->
$this->add(array(
'name' => 'packages',
'type' => 'MultiCheckbox',
'options' => array(
'label_attributes' => array(
'class' => 'checkbox inline',
),
'value_options' => array(
'germany' => 'Germany',
'austria' => 'Austria',
'switzerland' => 'Switzerland'
),
),
));
//-->
}
}
2. I have a InputFilter-Class called OrderFilter that extends
Zend\InputFilter\InputFilter:
class OrderFilter extends InputFilter
{
public function __construct()
{
//-->
$this->add(array(
'name'=> 'packages',
'required' => true,
'validators' => array(
array(
'name' => 'NotEmpty',
'options' => array(
'type' =>
\Zend\Validator\NotEmpty::ALL,
'message' => 'isRequired'
),
'break_chain_on_failure' => true,
),
),
));
//-->
}
}
3. I have a FormFactory-Class called OrderFormFactory:
class OrderFormFactory implements FactoryInterface
{
public function createService(ServiceLocatorInterface $serviceLocator)
{
$form = new OrderForm();
$form->setAttribute('method', 'post');
$form->removeAttribute('name');
$form->setInputFilter(new OrderFilter());
return $form;
}
}
So far so good, this works perfect. And now to my question:
The element which I added in step 1 gets a default InArray-Validator and the
required true option. BUT now I want to customize the standard validator
message for the require option, to get this working I add the NotEmpty
Validator to my form field (step 2). In step 3 I connect my form with my
InputFilter-Class and there start my problems. If I check my InputFilter
with $form->getInputFilter() I get the following ValidatorChain for my
"packages" element.
1. InArray-Validator
2. NotEmpty-Validator
The problem is now that my NotEmpty validator is after the InArray validator
and if I validate my form with an empty option now, I get both error
messages. Furthermore it doesn't make sense to have the NotEmpty-Validator
at the end of the ValidatorChain.
I know that the NotEmpty Validator is at the end because custom validators
are added to the validator chain. I also know methods like
prependValidator() but I couldn't use this method in my InputFilter-Class.
After hours of searching I found this
<https://github.com/zendframework/zf2/pull/3218#issuecomment-11535066> and
it already merged to ZF2. Unfortunately I don't understand the difference
between setPreferFormInputFilter(true) and useInputFilterDefaults(false). In
my eyes it does exactly the same but I know there is a difference between
for sure.
But both of this methods don't do what I want. These methods clear the
default validators from my element but I don't want to clear the InArray
Validator, I only want the NotEmpy validator with a custom error message
before the InArray Validator.
It would very nice, if someone could help me.
Stefan
