Question

由于使用PHP 7.0及更高版本，php的严格模式会生成如下警告：

PHP Warning: Declaration of In2code\Femanagerextended\Controller\EditController::updateAction(In2code\Femanagerextended\Domain\Model\User $user) should be compatible with In2code\Femanager\Controller\EditController::updateAction(In2code\Femanager\Domain\Model\User $user) in ($PATH)\typo3conf\ext\femanagerextended\Classes\Controller\EditController.php line 17

尝试使用本手册最佳实践部分中描述的方式扩展TYPO3 Extension femanager的现有控制器时：

<?php
namespace In2code\Femanagerextended\Controller;
use In2code\Femanager\Controller\EditController as EditControllerFemanager;
use In2code\Femanagerextended\Domain\Model\User;
/**
 * Class EditController
 *
 * @package In2code\Femanagerextended\Controller
 */
class EditController extends EditControllerFemanager
{
    /**
     * action update
     *
     * @param User $user
     * @validate $user In2code\Femanager\Domain\Validator\ServersideValidator
     * @validate $user In2code\Femanager\Domain\Validator\PasswordValidator
     * @return void
     */
     public function updateAction(User $user)
     {
         parent::updateAction($user);
     }
}

Answer 1

沃尔夫冈·克林格（Wolfgang Klinger）设计的一个可能的解决方案是XClass \ TYPO3 \ CMS \ Extbase \ Mvc \ Controller \ Argument class。

此类具有受保护的属性“dataType”，通常没有setter。

使用TYPO3的XClass机制，可以添加一个setDataType方法来启用手动覆盖此属性。

有了这个，现在可以在扩展编辑/邀请/新控制器的（魔术）初始化操作中覆盖通常自动检测到的数据类型。

重要的是，不更改“普通”动作（newAction，createAction ...）的类型提示和注释，但是将相应的内容添加到相应的初始化动作中：< / p>

public function initializeNewAction()
{
    if ($this->arguments->hasArgument('user')) {
        // Workaround to avoid php7 warnings of wrong type hint.
        /** @var \Mediagear\Jdcompetition\Xclass\Extbase\Mvc\Controller\Argument $user */
        $user = $this->arguments['user'];
        $user->setDataType(\Vendor\Extension\Domain\Model\User::class);
    }
}

您可以使用以下tutorial扩展TYPO3 femanager。不需要旧的扩展名femanagerextended。 TYPO3和PHP 5.x可以很好地工作。这是PHP 7.x的解决方法：

添加一个新的XCLASS文件f.e. typo3conf/ext/yourext/Classes/Xclass/Extbase/Mvc/Controller/Argument.php：

namespace Yournamespace\Yourext\Xclass\Extbase\Mvc\Controller;
class Argument extends \TYPO3\CMS\Extbase\Mvc\Controller\Argument

{
    /**
     * Set data type for femanager workaround.
     * Workaround to avoid php7 warnings of wrong type hint.
     *
     * @param $dataType
     * @return $this
     */
    public function setDataType($dataType) {
        $this->dataType = $dataType;
        return $this;
    }
}

更改文件typo3conf/ext/yourext/Classes/Controller/EditController.php：

namespace Yournamespace\Yourext\Controller;
use \Yournamespace\Yourext\Domain\Model\User;
class EditController extends \In2code\Femanager\Controller\EditController {

    /**
     * @return void
     */
    public function initializeUpdateAction()
    {
        if ($this->arguments->hasArgument('user')) {
            // Workaround to avoid php7 warnings of wrong type hint.
            /** @var \Yournamespace\Yourext\Xclass\Extbase\Mvc\Controller\Argument $user */
            $user = $this->arguments['user'];
            $user->setDataType(\Yournamespace\yourext\Domain\Model\User::class);
        }
    }

    /**
     * action update
     *
     * @param User $user
     * @validate $user In2code\Femanager\Domain\Validator\ServersideValidator
     * @validate $user In2code\Femanager\Domain\Validator\PasswordValidator
     * @validate $user In2code\Femanager\Domain\Validator\CaptchaValidator
     * @return void
     */
    public function updateAction(\In2code\Femanager\Domain\Model\User $user) {
        parent::updateAction($user);
    }
}

更改文件typo3conf/ext/yourext/Classes/Controller/NewController.php：

namespace Yournamespace\Yourext\Controller;
use Yournamespace\Yourext\Domain\Model\User;
class NewController extends \In2code\Femanager\Controller\NewController {

    /**
     * Initialize create action for setting the right custom data type for the user.
     */
    public function initializeCreateAction() {
        if ($this->arguments->hasArgument('user')) {
            // Workaround to avoid php7 warnings of wrong type hint.
            /** @var \Yournamespace\Yourext\Xclass\Extbase\Mvc\Controller\Argument $user */
            $user = $this->arguments['user'];
            $user->setDataType(\Yournamespace\Yourext\Domain\Model\User::class);
        }
    }


    /**
     * action create
     *
     * @param User $user
     * @validate $user In2code\Femanager\Domain\Validator\ServersideValidator
     * @validate $user In2code\Femanager\Domain\Validator\PasswordValidator
     * @return void
     */
    public function createAction(User $user)
    {
        parent::createAction($user);
    }
}

将您的XCLASS注册到ext_localconf.php中： $GLOBALS['TYPO3_CONF_VARS']['SYS']['Objects']['TYPO3\\CMS\\Extbase\\Mvc\\Controller\\Argument'] = array('className' => 'Yournamespace\\Yourext\\Xclass\\Extbase\\Mvc\\Controller\\Argument');

通过安装工具清除缓存并清除自动加载器！
