I wanna to use some global configuration in a form model. should I use the DI method to resolve this?  
I can not find any demo about the form-factory kind.

My form as follow, the role should be a configuration from global.php:

```auto
<?php
/**
 * user 用户表
 */

namespace Application\Form;

use Laminas\Filter\StringTrim;
use Laminas\Filter\StripTags;
use Laminas\Filter\ToInt;
use Laminas\Form\Element\Hidden;
use Laminas\Form\Element\MultiCheckbox;
use Laminas\Form\Element\Password;
use Laminas\Form\Element\Text;
use Laminas\Form\Form;
use Laminas\InputFilter\InputFilterProviderInterface;
use Laminas\Validator\EmailAddress;
use Laminas\Validator\NotEmpty;
use Laminas\Validator\Regex;

class UserForm extends Form implements InputFilterProviderInterface
{
    public function init() : void
    {
        $this->add([
            'name' => 'id',
            'type' => Hidden::class,
        ]);

        $this->add([
            'name' => 'username', //用户名，唯一
            'type' => Text::class,
            'attributes' => [
                'placeholder' => '输入用户名',
            ],
        ]);

        $this->add([
            'name' => 'realname', //真实姓名
            'type' => Text::class,
        ]);

        $this->add([
            'name' => 'passwd', //加点盐之后的sha1
            'type' => Password::class,
            'attributes' => [
                'placeholder' => '输入密码',
            ],
        ]);

        $this->add([
            'name' => 'repasswd', //确认密码
            'type' => Password::class,
            'attributes' => [

            'type' => Hidden::class,

        ]);

        $this->add([

            $vm->setTerminal(true);

        $form->setValidationGroup('username','mobile','email','role','passwd','repasswd');
        $form->setData($request->getPost());

        $vm = new ViewModel();

</div>

To create a simple form factory that has access to global config:

```auto
class MyFormFactory
{
    public function __invoke(ContainerInterface $container)
    {
        $form = new MyForm();
        $form->setConfig($container->get('config'));
        return $form;
    }
}

```

With your init method, use the config varibles to create your custom form

```auto
class MyForm extends Form
{
    var $config;

    public function init()
    {
        $this->add([
            'name' => 'role', //角色，用字符串加深理解
            'type' => MultiCheckbox::class,
            'options' => [
                'value_options' => [
                    $this->config['roles']['name'] => $this->config['roles']['value'],
                    ...
                ],
            ],
        ]);
    }
}

```

Your config file should have this entry:

```auto
'form_elements' => [
    'factories' => [
        MyForm::class => MyFormFactory::class,
    ],
],

```

To get that form into your controller, you cannot do so by creating the object. From the controller factory, retrieve the FormElementManger Object:

```auto
...
$form = $container->get('FormElementManager')->get(MyForm::class);
$controller->setForm($form);
...

```

Thank you so much!! That’s what exactly I am looking for!!

I followed your advise and it do acquire the configuration of project\_root/config/global.php  
But!!!  
When I changed the code to following, it changed on the html. It is no big deel, but cause a lot of trouble to me, because I use form Id as selector in my javascript code. I spent a lot of time to find out the problem. 😂

 ![11111](https://canada1.discourse-cdn.com/flex032/uploads/zendframework/original/2X/c/ccd4edb451f42d7bfec1065aa1a7bad1074332ce.png)

module/Application/config/module.config.php  
I added the following:

```auto
'form_elements' => [
        'factories' => [
            UserForm::class => UserFormFactory::class,
        ],
    ],

```

The userForm:

```auto
protected $roleArr = ['超级管理员' => '超级管理员', '编辑人员' => '编辑人员'];

    public function __construct($roleConfig)
    {
        $this->roleArr = $roleConfig;
        parent::__construct(null, []); //should I have to add this line???
    }

```

UserFormFactory:

```auto
public function __invoke(ContainerInterface $container, $requestedName, ?array $options = null)
    {
        $config = $container->get('config');
        return new UserForm($config['roleConfig']);
    }

```
