Question

我一直关注blog的zf2指南我创建了控制器，工厂，表格，映射器，模型，服务，视图等所有内容

在我的表单中，我有一个选择元素

$this->add(array(     
  'type' => 'select',       
  'name' => 'roleId',
  'attributes' =>  array(
    'id' => 'roleId',
    'options' => array(
        '1' => 'Admin',
        '2' => 'Manager',
    ),
  ),
  'options' => array(
    'label' => 'Role',
  ),
));

现在在这种形式中，我想从数据库加载角色的选项我尝试通过创建一个简单的函数来加载该选项，该函数可以在元素中访问，如下所示，但我无法获取结果。我已经创建了Controller，Factory，Form，Mapper，Model，Service和view，我可以在Role上进行CRUD操作。

$this->add(array(     
  'type' => 'select',       
  'name' => 'roleId',
  'attributes' =>  array(
    'id' => 'roleId',
    'options' => $this->getAllRoles(),
  ),
  'options' => array(
    'label' => 'Role',
  ),
));

public function getAllRoles()
{
  $roles = $this->getServiceLocator()->get('Admin\Service\RoleService');
  $allRoles = $this->getAllTheRoles();  
  return $allroles;
}

任何人都可以指导我如何加载Blog Post后面的IndexAction中列出的所有角色选项，其中包含角色的ID和名称。

Answer 1

您可以创建一个预先填充了角色的可重用表单元素。为此，您必须使用data <- structure(list(doy = c(264, 265, 266, 267, 268, 271, 272, 11,12, 13), Date = structure(c(1442824200, 1442910600, 1442997000,1443083400, 1443169800, 1443429000, 1443515400, 1452504600, 1452591000,1452677400), class = c("POSIXct", "POSIXt"), tzone = ""), OR_High = c(164.71,162.96, 163.38, 161.37, 163.91, 162.06, 160.22, 164.5, 165.23,165.84), OR_Low = c(164.37, 162.62, 162.98, 161.06, 163.57, 161.66,159.7, 164.06, 164.84, 165.4), HOD = c(165.56, 163.36, 163.38,162.24, 164.43, 162.06, 160.96, 164.5, 165.78, 165.84), LOD = c(165.22,163.1, 162.98, 161.95, 164.24, 161.66, 160.75, 164.06, 165.56,165.4), Close = c(164.92, 163.02, 162.58, 161.85, 162.94, 159.84,160.19, 163.83, 165.02, 161.38), Range = c(0.340000000000003,0.260000000000019, 0.400000000000006, 0.29000000000002, 0.189999999999998,0.400000000000006, 0.210000000000008, 0.439999999999998, 0.219999999999999,0.439999999999998), `A-val` = c(NA, NA, NA, NA, NA, NA, NA, 0.0673439999999994,0.0659639999999996, 0.0729499999999996), `A-up` = c(NA, NA, NA,NA, NA, NA, NA, 164.567344, 165.295964, 165.91295), `A-down` = c(NA,NA, NA, NA, NA, NA, NA, 163.992656, 164.774036, 165.32705)), .Names = c("doy","Date", "OR_High", "OR_Low", "HOD", "LOD", "Close", "Range","A-val", "A-up", "A-down"), row.names = c(1L, 2L, 3L, 4L, 5L,6L, 7L, 78L, 79L, 80L), class = "data.frame")中的表单元素管理器注册该服务。

module.config.php

不需要扩展标准选择类，因为更改只是配置。这最好在工厂类中完成。

return [
    'form_elements' => [
        'factories' => [
            'RoleSelect' => 'MyModule\Form\Element\RoleSelectFactory',
        ],
    ],
];

然后可以更新在表单中添加元素以使用我们注册的服务的名称。

namespace MyModule\Form\Element;

use Zend\Form\Element\Select;

class RoleSelectFactory
{
    public function __invoke($formElementManager, $name, $rname)
    {
        $select = new Select('role_id');

        $select->setOptions(['label' => 'Role']);
        $select->setAttributes(['id' => 'role_id']);

        $serviceManager = $formElementManager->getServiceLocator();
        $roleService = $serviceManager->get('Admin\Service\RoleService');

        $options = [];
        foreach($roleService->getAllTheRoles() as $role){
            $options[$role->getId()] => $role->getName();
        }

        $select->setValueOptions($options);

        return $select;
    }
}

要记住的一点是，必须使用$this->add([ 'name' => 'role_id' 'type' => 'RoleSelect', ]);创建使用此元素的表单。

Answer 2

终于找到了这样做的简单方法，我真的不确定这是否是正确的方法。

在用户控制器中添加了角色服务

我的userController.php中的代码

use Admin\Service\RoleServiceInterface;
class UserController extends AbstractActionController
{
  /**
  * @var \Admin\Service\UserServiceInterface
  */
  protected $userService;
  protected $roleService;
  protected $userForm;

  public function __construct(
    UserServiceInterface $userService,
    RoleServiceInterface $roleService,
    FormInterface $userForm
  )
  {
    $this->userService = $userService;
    $this->roleService = $roleService;
    $this->userForm    = $userForm;
  }

  public function addAction()
  {
    $request = $this->getRequest();
    $roles    = $this->roleService->findAllRoles();
    foreach ($roles as $role) {
      if($role->getStatus() == 1) {
        $allRoles[$role->getId()] = $role->getName();
      }
    }
    $this->userForm->__construct(null, array('roleOptions'=>$allRoles));
  }
}

我的UserControllerFactory.php

<?php

namespace Admin\Factory;

use Admin\Controller\UserController;
use Zend\ServiceManager\FactoryInterface;
use Zend\ServiceManager\ServiceLocatorInterface;

class UserControllerFactory implements FactoryInterface
{
  /**
  * Create service
  *
  * @param ServiceLocatorInterface $serviceLocator
  *
  * @return mixed
  */
  public function createService(ServiceLocatorInterface $serviceLocator)
  {
    $realServiceLocator = $serviceLocator->getServiceLocator();
    $userService        = $realServiceLocator->get('Admin\Service\UserServiceInterface');
    $roleService        = $realServiceLocator->get('Admin\Service\RoleServiceInterface');
    $userInsertForm     = $realServiceLocator->get('FormElementManager')->get('Admin\Form\UserForm');

    return new UserController(
    $userService,
    $roleService,
    $userInsertForm
    );
  }
}

最后是UserForm.php

<?php

namespace Admin\Form;

use Zend\Form\Form;
use Admin\Model\User;
use Zend\Stdlib\Hydrator\ClassMethods;
use Zend\Form\Element\Select;


class UserForm extends Form
{
  public function __construct($name = null, $options = array())
  {
    $roleOptions = array();
    if($options) {
      $roleOptions = $options['roleOptions'];
    }
    parent::__construct($name, $options);

    $this->setHydrator(new ClassMethods(false));
    $this->setObject(new User());
    $this->add(array(
      'type' => 'hidden',
      'name' => 'id'
    ));

   $this->add(array(     
     'type' => 'select',       
     'name' => 'roleId',
     'attributes' =>  array(
       'id' => 'roleId',
       'options' => $roleOptions
     ),
    'options' => array(
      'label' => 'Role',
    ),
    ));
  }
}

这种方式使用服务管理器我已成功加载my for Select选项。

在控制器内部调用getAllRoles()然后您可以在创建form对象时将自定义数组作为form的参数传递。在form __construct函数中，您可以检索该数组并像这样设置

'options'=＆gt; $角色，
