这是我来自控制器的编辑操作：

 public function editAction()
{
$this->layout('layout/myaccount');

$userTable = $this->getServiceLocator()->get('UserTable');

$user = $userTable->getUser($this->params()->fromRoute('id'));
$form = $this->getServiceLocator()->get('UserEditForm');
$form->bind($user);
$viewModel = new ViewModel(array('form' => $form, 'user_id' => $this->params()->fromRoute('id')));
return $viewModel;
}

我的表单代码

<?php
// filename : module/Users/src/Users/Form/RegisterForm.php
namespace Users\Form;

use Zend\Form\Form;

class UserEditForm extends Form
{
    public function __construct($name = null)
    {
        parent::__construct('Edit User');
        $this->setAttribute('method', 'post');
        $this->setAttribute('enctype','multipart/form-data');

        $this->add(array(
            'name' => 'id',
            'attributes' => array(
                'type'  => 'hidden',
            ),
        ));

        $this->add(array(
            'name' => 'name',
            'attributes' => array(
                'type'  => 'text',
                'required' => 'required'                                 
            ),
            'options' => array(
                'label' => 'Full Name',
            ),
        ));


        $this->add(array(
            'name' => 'email',
            'attributes' => array(
                'type'  => 'email',
                'required' => 'required'                 
            ),
            'options' => array(
                'label' => 'Email',
            ),
        )); 

        $this->add(array(
            'name' => 'submit',
            'attributes' => array(
                'type'  => 'submit',
                'value' => 'Save'
            ),
        )); 
    }
}

如果您需要我添加更多代码。

Answer 1

找不到UserEditForm。很可能您没有在服务管理器配置中定义其位置。确保定义

'service_manager' => array (
        'invokables' => array (
            'UserEditForm' => 'Users\Form\RegisterForm' 
        ), 
)
