Hello,
I am laminas newbie. I dont find an error constants for this example. How can I handle this?
php > $dtZone = new DateTimeZone(‘UTC’);
php > $dtString = ‘2019-02-31’;
php > $dt = new DateTime($dtString, $dtZone);
php > echo $dt->format(‘Y-m-d’);
2019-03-03
This example is an input to Form\Element\DateSelect. for this request only!

Hello and welcome to forums! 
Unfortunately I don’t know what your goal is.
The form element Laminas\Form\Element\DateSelect uses the Date validator from laminas-validator. There will you find all supported constants:
Maybe you can describe exactly what you have in mind then we can better help.
Hello. 
My english is terrible! Sorry about.
I builded a Form\Form and use inside Form\Element\DateSelect.
I see (in html ) Day-Select(01-31), Month-Select(01-12) and Year-Select(configure with max_year and min_year),
It works.
Unfortunately you can select 31.02.2019 and I see in database 2019-03-03.
I wanto to use in InputFilter:
‘options’ => [
‘messages’ => [
Validator\Date::ANY_CONST => ‘message’
]
}
Greetings
Please check which date value the form returns after validation:
if ($form->isValid()) {
var_dump($form->getData());
}
I forgot to activate validator. sorry!
But now i get ( after $form->isValid() ):
Array
(
[username] => test
[gender] => Male
[email] => test@example.de
[confirm_email] => test@example.de
[birthday] => NULL
[password] => test12345
[confirm_password] => test12346
[csrf] => dc90606f4a97f0d10ea0c030f83dd3d2-5555be22ef186525e50704a74e6e33b5
[create_account] => Account anlegen
)
Validator\NotEmpty should fire an error for birthday or? 
[
'name' => 'birthday',
'required' => true,
'filters' => [
[ 'name' => Filter\StripTags::class ] , # remove html tags
[ 'name' => Filter\StringTrim::class ] , # remove empty spaces
],
'validators' => [
[
'name' => Validator\NotEmpty::class,
'options' => [
'messages' => [
Validator\NotEmpty::INVALID => 'invalid',
Validator\NotEmpty::IS_EMPTY => 'Empty',
]
]
],
[
'name' => Validator\Date::class,
'options' => [
'format' => 'Y-m-d',
'messages' => [
Validator\Date::FALSEFORMAT => 'Birthday has wrong format',
Validator\Date::INVALID_DATE => 'Date ist not valid',
Validator\Date::INVALID => 'Invalid'
],
],
],
],
]
I inserted, what I found.
Here a short example to demonstrate different values for validation:
class ExampleForm extends Laminas\Form\Form
implements Laminas\InputFilter\InputFilterProviderInterface
{
public function init() : void
{
$this->add(
[
'name' => 'birthday',
'type' => Laminas\Form\Element\DateSelect::class,
]
);
}
public function getInputFilterSpecification() : array
{
return [
[
'name' => 'birthday',
'required' => true,
],
];
}
}
Validation with invalid value:
$form = new ExampleForm();
$form->init();
$form->setData(
[
'birthday' => '',
]
);
var_dump($form->isValid()); // false
var_dump($form->getMessages()['birthday']['isEmpty']); // "Value is required and can't be empty"
With valid values:
$form = new ExampleForm();
$form->init();
$form->setData(
[
'birthday' => '2020-07-01',
]
);
var_dump($form->isValid()); // true
$form = new ExampleForm();
$form->init();
$form->setData(
[
'birthday' => [
'year' => '2020',
'month' => '07',
'day' => '01',
],
]
);
var_dump($form->isValid()); // true
Maybe it will help to find your problem.
Thanks for the example
