Hi everyone,
I'm struggling to create a composite form element in ZF2 based on this ZF1
tutorial <http://www.mwop.net/blog/217-Creating-composite-elements.html> .
I've created my element in a custom library called 'Si':
namespace Si\Form\Element;use Zend\Form\Element;class DateSegmented extends
Element{ protected $_dateFormat = '%year%-%month%-%day%'; protected
$_day; protected $_month; protected $_year; /** * Seed
attributes * * @var array */ protected $attributes = array(
'type' => 'datesegmented', ); public function setDay($value) {
$this->_day = (int) $value; return $this; } public function
getDay() { return $this->_day; } public function
setMonth($value) { $this->_month = (int) $value; return
$this; } public function getMonth() { return $this->_month;
} public function setYear($value) { $this->_year = (int)
$value; return $this; } public function getYear() {
return $this->_year; } public function setValue($value) {
if (is_int($value)) { $this->setDay(date('d', $value))
->setMonth(date('m', $value)) ->setYear(date('Y', $value));
} elseif (is_string($value)) { $date = strtotime($value);
$this->setDay(date('d', $date)) ->setMonth(date('m', $date))
->setYear(date('Y', $date)); } elseif (is_array($value) &&
(isset($value['day']) && isset($value['month'])
&& isset($value['year']) ) ) {
$this->setDay($value['day']) ->setMonth($value['month'])
->setYear($value['year']); } else { throw new
Exception('Invalid date value provided'); } return
$this; } public function getValue() { return
str_replace( array('%year%', '%month%', '%day%'),
array($this->getYear(), $this->getMonth(), $this->getDay()),
$this->_dateFormat ); }}
And then the view helper:
namespace Si\Form\View\Helper;use Zend\Form\View\Helper\FormElement;use
Zend\Form\Element;use Zend\Form\ElementInterface;use
Zend\Form\Exception;class DateSegmented extends FormElement{ /** *
Render a form input> element from the provided $element * * @param
ElementInterface $element * @throws Exception\InvalidArgumentException
* @throws Exception\DomainException * @return string */ public
function render(ElementInterface $element) { $content = "";
if (!$element instanceof \Si\Form\Element\DateSegmented) { throw
new Exception\InvalidArgumentException(sprintf( '%s requires
that the element is of type Si\Form\Input\DateSegmented',
__METHOD__ )); } $name = $element->getName();
if (empty($name) && $name !== 0) { throw new
Exception\DomainException(sprintf( '%s requires that the
element has an assigned name; none discovered', __METHOD__
)); } $day = $element->getDay(); $month =
$element->getMonth(); $year = $element->getYear();
$params = array( 'size' => 2, 'maxlength' => 2
); $yearParams = array( 'size' => 4,
'maxlength' => 4, ); $markup = ""; $elementText
= new \Zend\Form\Element\Text($name . '[day]', $params);
$elementText->setValue($day); $markup .=
$this->view->formText($elementText); $elementText = new
\Zend\Form\Element\Text($name . '[month]', $params);
$elementText->setValue($month); $markup .=
$this->view->formText($elementText); $elementText = new
\Zend\Form\Element\Text($name . '[year]', $yearParams);
$elementText->setValue($year); $markup .=
$this->view->formText($elementText); return $markup; }
/** * Return input type * * @return string */ protected
function getInputType() { return 'datesegmented'; } }
The element has been set as invokable in my custom library
'HelperConfig.php' file.
namespace Si\Form\View;use Zend\ServiceManager\ConfigInterface;use
Zend\ServiceManager\ServiceManager;class HelperConfig implements
ConfigInterface{ /** * @var array Pre-aliased view helpers */
protected $invokables = array( 'datesegmented' =>
'\Si\Form\View\Helper\DateSegmented', ); /** * Configure the
provided service manager instance with the configuration * in this
class. * * Adds the invokables defined in this class to the SM
managing helpers. * * @param ServiceManager $serviceManager *
@return void */ public function
configureServiceManager(ServiceManager $serviceManager) { foreach
($this->invokables as $name => $service) {
$serviceManager->setInvokableClass($name, $service); } }}
The above code generated the three input fields and also returns them as an
array in the raw POST. If I run 'getValue()' against the element, I get the
correct value. Unfortunately, the validator still seems to get the old array
(which at this point has been flattened into a string called 'Array') and
fails.
In ZF1, you would overrite the 'getValue' function to work with validators.
What do I need to do for my adjusted value to be picked up by the validators
in ZF2?Thanks!Oli
