        $this->add(array(
            'name' => 'services',
            'type' => 'Zend\Form\Element\Textarea',
            'options' => array(
                'label' => 'услуги',

        ));

        $this->add(array(
            'name' => 'submit',
            'type' => 'Submit',
            'attributes' => array(
                'value' => 'сохранить',
                'id' => 'submitbutton',
            ),
        ));
    }
}

But then I try to show it controller shows fatal error class Addstudent not found. here is how I imported it to a controller

use admin\Model\Admin;
use admin\form\Addstudent;

And here is an action

public function addstudentAction()
{

    $form = new Addstudent();
    $form->get('submit')->setValue('Сохранить');

    $request = $this->getRequest();
    if ($request->isPost()) {
        $admin = new Admin();
        $form->setInputFilter($admin->getInputFilter());
        $form->setData($request->getPost());

        if ($form->isValid()) {
            $admin->exchangeArray($form->getData());
           // $this->getAlbumTable()->saveAlbum($album);

            // Redirect to list of albums
            return $this->redirect()->toRoute('admin');
        }
    }
    return array('form' => $form);


  //  return array();
}

form file is located in module/admin/src/admin/form/addstudent.php

Answer 1

Everything beneath your src folder should use an initial upper case letter, so module/admin/src/admin/form/addstudent.php should be module/admin/src/Admin/Form/Addstudent.php and so on.

Then you should change your namespace declarations to match this, i.e. namespace Admin\Form; and use Admin\Form\Addstudent;.

At the moment you are not being consistent about case (e.g. you declare namespace admin\Form; but have use admin\form\Addstudent; in your controller) which is likely the cause of your issue.

Answer 2

I had the very same problem. The autoloader didn't work. My project hasn't a lot of forms, so I have put this into my Bootstrap:

protected function _initAutoload()
{
   require_once APPLICATION_PATH . '/forms/Contact.php';
   require_once APPLICATION_PATH . '/forms/Participant.php';
}

But few days ago I solved my problem. The Zend library of mine wasn't in the project's folder "library", but few adresaries above(I changed the paths in settings and index.php). Since I moved it into project's folder "library", autoloader seems to be working fine.

Do you have this problem with other forms/tables? Cause I did.
