Question

我在 ZF2 中有登录和退出系统。我想在他/她登录时显示登录用户的用户名。屏幕截图如下：

我有不同的观点，例如view / provinces / index.phtml，view / districts / index.phtml等。

我在view / layout / layout.phtml中有layout.phtml，其中我描述了admin的布局，适用于每个视图。因此，有必要在layout.phtml中访问登录用户的用户名。

我还有相应的控制器，如Controller / ProvincesController.php，Controller / DistrictsController.php等。我可以在Controller / ProvincesController.php中访问登录用户的用户名等等代码：

public function getAuthService()
{
    $this->authservice = $this->getServiceLocator()->get('AuthService'); 
    return $this->authservice;  
}

$username = $this->getAuthService()->getStorage()->read();

但我无法在layout.phtml中访问登录用户用户名的值。

因此，如果有人知道它或有简单的想法或做法，请告诉我。

推荐的方法是使用identity（https://framework.zend.com/manual/2.4/en/modules/zend.view.helpers.identity.html）视图助手。然后在任何视图模型中，您可以按如下方式使用它：

if ($user = $this->identity()) {
     echo 'Logged in as ' . $this->escapeHtml($user->getUsername());
 } else {
     echo 'Not logged in';
 }

为了使其正常工作，您必须以特定名称Zend\Authentication\AuthenticationService注册您的身份验证服务。

因此，在module.config.php文件中，添加到service_manager：

'service_manager' => array(
    'aliases' => array(
        'Zend\Authentication\AuthenticationService' => 'AuthService', // <--- this line
    ),
    'invokables' => array(
        'AuthService' => 'Your\Authentication\Class',
    ),
),

然后你应该可以使用identity控制器插件并查看助手。

在您的情况下，Module.php应如下所示：

...
public function getServiceConfig()
{
    return array(
        'abstract_factories' => array(),
        'aliases' => array(
             'Zend\Authentication\AuthenticationService' => 'AuthService', // <--- this line
         ),

        'factories' => array( 

        // SERVICES
          'AuthService' => function($sm) {
            $dbAdapter = $sm->get('Zend\Db\Adapter\Adapter');
            $dbTableAuthAdapter = new DbTableAuthAdapter($dbAdapter, 'user','username','password', 'MD5(?)');

            $authService = new AuthenticationService();
            $authService->setAdapter($dbTableAuthAdapter);
            return $authService;
          },    

          // DB
          'UserTable' =>  function($sm) {
            $tableGateway = $sm->get('UserTableGateway');
            $table = new UserTable($tableGateway);
            return $table;
          },
          'UserTableGateway' => function ($sm) {
            $dbAdapter = $sm->get('Zend\Db\Adapter\Adapter');
            $resultSetPrototype = new ResultSet();
            $resultSetPrototype->setArrayObjectPrototype(new User());
            return new TableGateway('user', $dbAdapter, null,   
            $resultSetPrototype);
          },

          // FORMS
          'LoginForm' => function ($sm) {
            $form = new \Admin\Form\LoginForm();
            $form->setInputFilter($sm->get('LoginFilter'));
            return $form;
          },


           // FILTERS
          'LoginFilter' => function ($sm) {
            return new \Admin\Form\LoginFilter();
           },


            'Admin\Model\ProvincesTable' =>  function($sm) {
                $tableGateway = $sm->get('ProvincesTableGateway');
                $table = new ProvincesTable($tableGateway);
                return $table;
            },
            'ProvincesTableGateway' => function ($sm) {
                $dbAdapter = $sm->get('Zend\Db\Adapter\Adapter');
                $resultSetPrototype = new ResultSet();
                $resultSetPrototype->setArrayObjectPrototype(new Provinces());
                return new TableGateway('provinces', $dbAdapter, null, $resultSetPrototype);
            },

            'Admin\Model\DistrictsTable' =>  function($sm) {
                $tableGateway = $sm->get('DistrictsTableGateway');
                $table = new DistrictsTable($tableGateway);
                return $table;
            },
            'DistrictsTableGateway' => function ($sm) {
                $dbAdapter = $sm->get('Zend\Db\Adapter\Adapter');
                $resultSetPrototype = new ResultSet();
                $resultSetPrototype->setArrayObjectPrototype(new Districts());
                return new TableGateway('districts', $dbAdapter, null, $resultSetPrototype);
            },



        ),

        'invokables' => array(),
        'services' => array(),
        'shared' => array(),

    );
} 
...

然后在你的布局或任何其他.phtml文件中：

layout.phtml
...
<?php if ($this->identity()): ?>
<p>Welcome, <?php echo $this->identity()->getUsername(); ?></p>
<?php endif; ?>

Answer 2

在SzymonM先生的回答帮助下，我按照他的建议更改了我的Module.php，并在layout.phtml中编写以下简单代码

这解决了我的问题，用大写字母的第一个字母显示了用户名。

<?php 
    if ($this->identity())
    {  
        echo ucfirst($this->identity());    
    } 
?>  
//ucfirst is php function which make first letter Uppercase.
