zend框架2從插件查詢

Question

我怎樣才能從zend框架插件查詢？ ZF2 MVC global function

這裏是我當前的代碼在我的插件： 我創建插件使用此代碼

namespace Users\Controller\Plugin; 
use Zend\Mvc\Controller\Plugin\AbstractPlugin; 
use Zend\Mvc\Controller\AbstractActionController; 
use Zend\Session\Container as SessionContainer; 
use Zend\Session\Container; 
use Zend\Db\Adapter\Adapter; 

class MenuPlugin extends AbstractPlugin 
{ 
    protected $permissionsTable; 

    public function availableLinks($theController = '', $modules = '') 
    { 
     $moduleId  = 0; 
     foreach ($modules as $row) { 
      $moduleId = $row->id; 
     } 
     $session_user = new Container('user'); 
     $roleId   = $session_user->user_data['roleId']; 
     $the_functions = $this->getPermissionsTable()->getAvailableFunctions($moduleId,$roleId); 
     return $the_functions; 
    } 

    public function getPermissionsTable() 
    { 
     if (!$this->permissionsTable) 
     { 
      $sm = $this->getServiceLocator(); 
      $this->permissionsTable = $sm->get('Users\Model\PermissionsTable'); 
     } 
     return $this->permissionsTable; 
    } 
}

你應該叫$這個 - > getServiceLocator（） - > getServiceLocator（）;以獲得主要的服務經理。當你調用$ this-> getServiceLocator（）時，你只需要插件管理器。並且您還應該實現ServiceLocatorAwareInterface，以便系統將插件管理器注入到您的插件對象中。總而言之，你的代碼應該是這個樣子：

//... 
use Zend\ServiceManager\ServiceLocatorAwareInterface; 
use Zend\ServiceManager\ServiceLocatorAwareTrait; 

class MenuPlugin extends AbstractPlugin implements ServiceLocatorAwareInterface 
{ 

    use ServiceLocatorAwareTrait; 

    protected $permissionsTable; 

    public function availableLinks($theController = '', $modules = '') 
    { 
     $moduleId  = 0; 
     foreach ($modules as $row) { 
      $moduleId = $row->id; 
     } 
     $session_user = new Container('user'); 
     $roleId   = $session_user->user_data['roleId']; 
     $the_functions = $this->getPermissionsTable()->getAvailableFunctions($moduleId,$roleId); 
     return $the_functions; 
    } 

    public function getPermissionsTable() 
    { 
     if (!$this->permissionsTable) 
     { 
      $sm = $this->getServiceLocator()->getServiceLocator(); 
      $this->permissionsTable = $sm->get('Users\Model\PermissionsTable'); 
     } 
     return $this->permissionsTable; 
    } 
} 

不過，我自己的PHP版本不支持的特徵，然後將下面的代碼添加到類：

use Zend\ServiceManager\ServiceLocatorInterface 

private $serviceLocator; 

public function setServiceLocator(ServiceLocatorInterface $serviceLocator) 
{ 
    $this->serviceLocator = $serviceLocator; 
} 

public function getServiceLocator() 
{ 
    return $this->serviceLocator; 
}
