php - 如何在 Zend Framework 的 Controller 插件中获取引导资源

Question

protected function _initDatabase()
{
     $params = array(
            'host'     => '',
            'username' => '',
            'password' => '',
            'dbname'   => '',
        );

    $database = Zend_Db::factory('PDO_MYSQL', $params);
    $database->getConnection();
    return $database;
}

.

class App_Controller_Plugin_Test extends Zend_Controller_Plugin_Abstract
{
    public function preDispatch(Zend_Controller_Request_Http $request)
    {
        // how i get database?

    }
}

您始终可以获得对前端 Controller 的引用:

$front = Zend_Controller_Front::getInstance();

从那里你可以获得 Bootstrap :

$bootstrap = $front->getParam("bootstrap");

从 bootstrap 中你可以获得 bootstrap 插件:

if ($bootstrap->hasPluginResource("database")) {
      $dbResource = $bootstrap->getPluginResource("database");
}
$db = $dbResource->getDatabase();

但这需要很多额外的管道!

老实说，您最好在引导过程中将数据库适配器对象存储在注册表中:

protected function _initDatabase()
{
     $params = array(
            'host'     => '',
            'username' => '',
            'password' => '',
            'dbname'   => '',
        );

    $database = Zend_Db::factory('PDO_MYSQL', $params);
    $database->getConnection();
    Zend_Registry::set("database", $database);
    return $database;
}

然后你可以在任何地方获取数据库适配器:

Zend_Registry::get("database");
