Parse date in ZF2 - php

Question

I'm having a problem.
I'm using ZF2, and getting an error here.
$inputFilter->add($factory->createInput(array(
'name' => 'dataInicial',
'required' => true,
'validators' => array(
array(
'name' => 'NotEmpty',
'options' => array(
'messages' => array(
\Zend\Validator\NotEmpty::IS_EMPTY => 'A data do feriado deve ser preenchida.'
)
)
),
array(
'name' => 'callback',
'options' => array(
'messages' => array(
\Zend\Validator\Callback::INVALID_CALLBACK => 'Data no formato inválido.'
),
'callback' => function ($value, $context = array()) {
$dataInicial = \DateTime::createFromFormat('d/m/Y', $value);
return $dataInicial->format('d/m/Y');
}
)
)
)
)));
I'm getting this error:
DateTime::__construct(): Failed to parse time string (25/12/2014) at position 0 (2): Unexpected character
When I execute the same code in pure php, without zend, it works ok.
echo DateTime::createFromFormat('d/m/Y', '25/12/2014')->format('d/m/Y');
Maybe someone knows what's causing the error? Sorry for my english

Don't know what kind of database backend and relationship mapping but the issue is related to how the date is being stored I imagine, most likely like: Y/m/d
If you saving and getting this error then it's because you need the date in this format. If you are hydrating you may also need a date strategy to deal with hydration like:
// InputFilter.php
class yourInputFilter()
{
$hydrator->getHydrator()->addStrategy('my_attribute', new MyDateHydrationStrategy());
$this->add( array(
'name' => 'registration_starts',
'type' => 'Zend\Form\Element\DateTime',
'options' => array (
'format'=>'Y/m/d',
)
));
}
// YourForm.php
class YourForm Extends ....
{
$dateTime = new Element\DateTime('youDate');
$dateTime->setLabel('Date')
->setOptions(array(
'format' => 'Y-m-d\TH:iP'
));
}
// Strategy.php
class myDateTimeStrategy implements StrategyInterface
{
public function hydrate($value)
{
if (is_string($value)) {
$value = new DateTime($value);
}
// Could return in a different format, probably can't though because of when you need to edit
// return $value->format("m-d-Y")
return $value;
}
}
You will also need to change js settings if you using a datetime widget picker:
Which will be something like:
$('.datepicker').datepicker('format', 'yyyy/mm/dd');
Depending on which one you using.
