I have a problem in validating the array of value of an element. I search a lot find a callback function to validate that data.
Below is the validation code which i am using but it is not working
<?php
namespace Tutorials\Form;
use Zend\InputFilter\Factory as InputFactory; // <-- Add this import
use Zend\InputFilter\InputFilter; // <-- Add this import
use Zend\InputFilter\InputFilterAwareInterface; // <-- Add this import
use Zend\InputFilter\InputFilterInterface;
use Zend\Validator\Callback;
use Zend\I18n\Validator\Alpha;
class AddSubTopicFilterForm extends InputFilter implements InputFilterAwareInterface {
protected $inputFilter;
public $topicData;
public $subTopicData;
function __construct($data = array()) {
$articles = new \Zend\InputFilter\CollectionInputFilter();
$articlesInputFilter = new \Zend\InputFilter\InputFilter();
$articles->setInputFilter($articlesInputFilter);
$this->add(new \Zend\InputFilter\Input('title'));
$this->add($articles, 'articles');
if(!empty($data['data']['topic_name'])) {
$this->topicData = $data['data']['topic_name'];
}
if(!empty($data['data']['sub_topic_name'])) {
$this->subTopicData = $data['data']['sub_topic_name'];
}
}
public function setInputFilter(InputFilterInterface $inputFilter){
throw new \Exception("Not used");
}
public function getInputFilter(){
if (!$this->inputFilter) {
$dataTopic = $this->topicData;
$dataSubTopic = $this->subTopicData;
$inputFilter = new InputFilter();
$factory = new InputFactory();
$inputFilter->add($factory->createInput(array(
'name' => 'topic_name',
'required' => true,
'filters' => array(
array('name' => 'StripTags'),
array('name' => 'StringTrim'),
),
'validators' => array(
array(
'name' => 'Callback',
'options' => array(
'messages' => array(
\Zend\Validator\Callback::INVALID_VALUE => 'Seletec value is not valid',
),
"callback" => function() use ($dataTopic) {
$strip = new \Zend\I18n\Validator\IsInt();
foreach($dataTopic as $key => $tag) {
$tag = $strip->isValid((int)$tag);
$dataTopic[$key] = $tag;
}
return $dataTopic;
},
),
),
),
)));
$inputFilter->add($factory->createInput(array(
'name' => 'sub_topic_name',
'required' => true,
'filters' => array(
array('name' => 'StripTags'),
array('name' => 'StringTrim'),
),
'validators' => array(
array(
'name' => 'Callback',
'options' => array(
'messages' => array(
\Zend\Validator\Callback::INVALID_VALUE => 'Invalid Sub Topic Name',
),
"callback" => function() use ($dataSubTopic) {
$strip = new \Zend\Validator\StringLength(array('encoding' => 'UTF-8','min' => 1,'max' => 100));
foreach($dataSubTopic as $key => $tag) {
$tag = $strip->isValid($tag);
$dataSubTopic[$key] = $tag;
}
return $dataSubTopic;
},
),
),
),
)));
$this->inputFilter = $inputFilter;
}
return $this->inputFilter;
}
}
In the above line of code the value of $data['data']['topic_name']=array('0' => 1,'1' => 1)
and $data['data']['sub_topic_name']=array('0'=>'Testing','1'=>'Testing1');
and i am calling it $form = new AddSubTopicForm(); $logFilterForm = new AddSubTopicFilterForm(); $form->setInputFilter($logFilterForm->getInputFilter()); $form->setData($request->getPost());
Below is the of the form class
<?php
namespace Tutorials\Form;
use Zend\Form\Element;
use Zend\Form\Form;
class AddSubTopicForm extends Form {
public function __construct($data = array()){
parent::__construct('AddSubTopic');
$this->setAttribute('class', 'form-horizontal');
$this->setAttribute('novalidate', 'novalidate');
$this->add(array(
'type' => 'Zend\Form\Element\Select',
'name' => 'topic_name[]',
'attributes' => array(
'id' => 'topic_name',
'class' => 'form-control',
),
'options' => array(
'label' => ' Topic Name',
'empty_option'=>'---None--- ',
'value_options' => array(
'1' => 'PHP'
),
),
));
$this->add(array(
'name' => 'sub_topic_name[]',
'attributes' => array(
'type' => 'text',
'id' => 'sub_topic_name',
'class' => 'form-control',
'value' => ''
),
'options' => array(
'label' => ' Sub Topic Name',
),
));
$this->add(array(
'name' => 'id',
'attributes' => array(
'type' => 'hidden',
'id' => 'id'
)
));
$button = new Element('add_more_sub_topic');
$button->setValue('+AddMore');
$button->setAttributes(array(
'type' => 'button',
'id'=>'add_more',
'class'=>'btn btn-info'
));
$save = new Element('save');
$save->setValue('Save');
$save->setAttributes(array(
'type' => 'submit',
'id'=>'save',
'class'=>'btn btn-info'
));
$reset = new Element('reset');
$reset->setValue('Reset');
$reset->setAttributes(array(
'type' => 'reset',
'id'=>'reset',
'class'=>'btn'
));
$this->add($button);
$this->add($save);
$this->add($reset);
}//end of function_construct.
}//end of registration form class.
But it is not calling the filter callback function rather give me an error on first first form field that 'value is required ,can't be empty'
I don't why it is not validating data.Suggest me what where i am wrong and how can i overcome from this problem. Any help would be appreciated. Than.x
