I am trying to create a single abstract class to manage input validation - in this class I have static functions that return InputFilterInterface objects that I can then add to my interface in the model class that handles the data. However, none of the data ever seems to be validated even though it is valid. I am not using Forms, by the way - the data is coming in via Ajax rather than an HTML form.
Here is my code:
Central Library:
abastract class InputFilters {
public static function monthIDFilter($fieldName = 'monthID', $required = FALSE) {
$factory = new InputFactory();
return $factory->createInputFilter(array(
$fieldName => array(
'name' => $fieldName,
'required' => $required,
'validators' => array(
array('name' => 'not_empty'),
array('name' => 'string_length', 'options' => array(
'min'=>'6', 'max'=>'6'
)),
array('name' => 'regex', 'options'=>array(
'pattern' => '/^[0-9]{6}$/'
))
),
)
));
}
}
Model:
class DataModel implements \Zend\InputFilter\InputFilterAwareInterface {
protected $_inputFilter;
public function __construct()
{
$this->setInputFilter(InputFilters::monthIDFilter());
}
public function setInputFilter(InputFilterInterface $inputfilter)
{
if(!$this->_inputFilter) {
$this->_inputFilter = new InputFilter();
}
$this->_inputFilter->add($inputfilter);
}
public function getInputFilter()
{
if(!$this->_inputFilter) {
$this->_inputFilter = new InputFilter();
}
return $this->_inputFilter;
}
}
And finally, in the controller:
public function dataAction()
{
$model = new DataModel();
$inputFilter = $model->getInputFilter();
$inputFilter->setData($_REQUEST);
print_r($_REQUEST);
print_r($inputFilter->getValues());
if ($inputFilter->isValid()) {
if ($inputFilter->has('monthID')) {
echo $inputFilter->getValue('monthID');
$formMonth = $inputFilter->getValue('monthID');
} else {
echo 'nope';
$formMonth = '';
}
$grid->setSqlString($formMonth);
$data = $grid->outputData();
Json::out($data);
}
In my output, I see the input that contains my monthID (201212) and an array that should be the validation results: Array ( [] => Array ( [monthID] => ) ) and the word 'nope' indicating that the has('monthID') check failed.
Any advice as to where I went wrong?
