Disable Inarray Validator on Zend Form - php

Question

I have a form that was working until I added two dropdown menus. Since then, upon the submission of the form I get the error:
haystack option is mandatory
This is my ProjectForm.php
<?php
namespace Project\Form;
use Zend\Form\Form;

public function isValidJSON($value, $options) {

public function getInputFilterSpecification() {
return array(

'filters' => array(
array(
'name' => 'Zend\Filter\StringTrim'

),
'validators' => array(
new Callback(
array(
$this,
'isValidJSON'
)),
),
),
ProjectForm::KEY_PROJECT_WORKFLOW_CONFIG => array(

),
),
'validators' => array(
new Callback(
array(
$this,
'isValidDateTime'
)),

),
);
}
}
I think I need to disable the inarray_validator by adding disable_inarray_validator' => true but I'm not sure where to add this.

Answer 1

Because of the version of Zend that I am using, I had to add this to the controller before validating the form:
// Make certain to merge the files info!
$post = array_merge_recursive($request->getPost()->toArray(), $request->getFiles()->toArray());
//Deals with validation of dynamic form
$projectType = $projectTypes[$post["project_types"]];
$form->get('project_workflow_types')->setValueOptions($workflowTypes[$projectType]);
// set the form instance's data
$form->setData($post);

Answer 2

I suggest you pass an empty string as a unique valueOption. In your javascript you flush the <option> tags of the select to get rid of this empty option.
Also you will have to disable the default validator of the Select element by adding :
$projectWorkflowDropDown->setOptions(array('disable_inarray_validator' => true));
Or
$projectWorkflowDropDown->setDisableInArrayValidator(true);
If you don't add this option, when the form will be submitted, Zend Form will tell you the value send is not in the haystack provided when the form was built. This is a safety process which is very helpful in many cases, just not in your.
