My ZF2 Form Field set validation is not working but form validation is working I have tried same a form validation, but these are not working.
I have implemented InputFilterProviderInterface in field set but it is not working.
Below is my code:
class CompanyCreditLimitFieldset extends Fieldset implements InputFilterProviderInterface {
protected $_curency = null;
protected $inputFilter;
public function __construct($name = null, $options = array()) {
$this
->setHydrator(new ClassMethodsHydrator(false))
->setObject(new \Application\Entity\PhvCompanyCurrencyCredit())
;
parent::__construct($name, $options);
$this->add(array(
'name' => 'credit_limit',
'type' => 'text',
'attributes' => array(
'id' => 'credit_limit',
'class' => 'form-control maxlength-simple credit_limit',
'placeholder' => 'Credit Limit'
),
'options' => array(
'label' => 'Credit Limit',
)
));
$this->add(array(
'name' => 'mininum_balance_limit',
'type' => 'text',
'attributes' => array(
'id' => 'mininum_balance_limit',
'class' => 'form-control maxlength-simple mininum_balance_limit',
'placeholder' => 'Minimum Balance Limit'
),
'options' => array(
'label' => 'Minimum Balance Limit',
)
));
}
public function getInputFilterSpecification() {
return array(
'credit_limit' => array(
'filters' => array(
array('name' => 'StringTrim')
),
'validators' => array(
array('name' => 'NotEmpty')
)
),
'mininum_balance_limit' => array(
'filters' => array(
array('name' => 'StringTrim')
),
'validators' => array(
array('name' => 'NotEmpty')
)
),
);
}
}
Form
class AddCompanyForm extends AbstractForm implements InputFilterAwareInterface {
protected $inputFilter;
protected $dbAdapter;
private $_country = null;
public function __construct($id = null, $name = null) {
$this->entity = new \Application\Entity\PhvCompany();
parent::__construct($name);
$this
->setHydrator(new ClassMethodsHydrator(false))
->setObject(new \Application\Entity\PhvCompany())
;
$this->__addElements();
}
private function __addElements() {
$this->setAttribute('method', 'post');
$this->add(array(
'type' => 'Zend\Form\Element\Collection',
'name' => 'creditlimitfieldset',
'options' => array(
'label' => 'Credit Limits',
'count' => 3,
'allow_add' => true,
'should_create_template' => true,
'template_placeholder' => '__placeholder__',
'target_element' => array(
'type' => 'Application\Form\Fieldset\CompanyCreditLimitFieldset',
),
),
// 'type' => 'Application\Form\Fieldset\CompanyCreditLimitFieldset',
// 'options' => array('label' => 'Credit Limits',)
));
$this->add(array(
'name' => 'submit',
'attributes' => array(
'type' => 'submit',
'value' => 'Save',
'class' => 'btn btn-inline btn-secondary btn-rounded'
)
));
}
public function setDbAdapter($dbAdapter) {
$this->dbAdapter = $dbAdapter;
}
public function setInputFilter(InputFilterInterface $inputFilter) {
throw new \Exception("Not used");
}
}
Can you please help me to solve this issue.
Frankly, this type of problem is why I always build a separate InputFilter hierarchy matching the Form structure instead of relying on ZF's "magic" input filter builder. Here's a great article on how to do that:
When working with collections in this manner you'll need to add a CollectionInputFilter to the form's input filter for each Collection form element. That class is completely undocumented IIRC, but you can find an example here and the class here.
I wrote a short script that reproduces what you're seeing:
<?php
<<<CONFIG
packages:
- "zendframework/zend-form: ^2.0"
- "zendframework/zend-servicemanager: ^3.0"
- "zendframework/zend-hydrator: ^2.0"
CONFIG;
// Run this script with Melody: http://melody.sensiolabs.org/
use Zend\Form\Fieldset;
use Zend\InputFilter\InputFilterProviderInterface;
use Zend\Form\Form;
class ChildFieldset extends Fieldset implements InputFilterProviderInterface
{
public function __construct($name = null, $options = array())
{
parent::__construct($name, $options);
$this->add(array(
'name' => 'fieldA',
'type' => 'text',
'attributes' => array(
'id' => 'fieldA',
),
'options' => array(
'label' => 'Field A',
)
));
}
public function getInputFilterSpecification()
{
return array(
'fieldA' => array(
'required' => true,
'allow_empty' => false,
'continue_if_empty' => false,
'filters' => array(
array('name' => 'StringTrim')
),
'validators' => array(
array('name' => 'NotEmpty')
)
),
);
}
}
class ParentForm extends Form
{
public function __construct($name, array $options)
{
parent::__construct($name, $options);
$this->add(array(
'type' => 'Zend\Form\Element\Collection',
'name' => 'childForms',
'options' => array(
'label' => 'Child Forms',
'allow_add' => true,
'should_create_template' => true,
'template_placeholder' => '__placeholder__',
'target_element' => array(
'type' => 'ChildFieldset',
),
),
));
$this->add(array(
'name' => 'submit',
'attributes' => array(
'type' => 'submit',
'value' => 'Save',
)
));
}
}
$form = new ParentForm('foo', []);
$data = [];
$form->setData($data);
echo "Dataset: " . print_r($data, true) . "\n";
echo "Result: " . ($form->isValid() ? 'valid' : 'invalid');
echo "\n\n--------------------------------------\n\n";
$data = [
'childForms' => []
];
$form->setData($data);
echo "Dataset: " . print_r($data, true) . "\n";
echo "Result: " . ($form->isValid() ? 'valid' : 'invalid');
echo "\n\n--------------------------------------\n\n";
$data = [
'childForms' => [
['fieldA' => ''],
],
];
$form->setData($data);
echo "Dataset: " . print_r($data, true) . "\n";
echo "Result: " . ($form->isValid() ? 'valid' : 'invalid') . "\n\n";
echo "\n\n--------------------------------------\n\n";
$data = [
'childForms' => [
['fieldA' => 'fff'],
],
];
$form->setData($data);
echo "Dataset: " . print_r($data, true) . "\n";
echo "Result: " . ($form->isValid() ? 'valid' : 'invalid') . "\n\n";
and when I run it (PHP 7.0.9) I get this:
Dataset: Array
(
)
Result: valid
(wrong)
--------------------------------------
Dataset: Array
(
[childForms] => Array
(
)
)
Result: valid
(wrong)
--------------------------------------
Dataset: Array
(
[childForms] => Array
(
[0] => Array
(
[fieldA] =>
)
)
)
Result: invalid
(correct!)
--------------------------------------
Dataset: Array
(
[childForms] => Array
(
[0] => Array
(
[fieldA] => fff
)
)
)
Result: valid
(correct!)
The input filter on the child fieldset is only triggered when the full hierarchy of keys exist in the data. It's not a bug per se, but it's not what you expect to happen.
