如何从Zend Framework 2中的布局/视图脚本中自动加载的配置文件访问配置？ [英] How to access configs from autoloaded config files in a layout / view script in Zend Framework 2?

问题描述

我想/必须在 ZF1风格中管理一些设置，并向视图提供有关当前环境的信息。

/config/application.config.php

  return array（
 ... 
'module_listener_options'=> array（
 ... 
'config_glob_paths'=> array（'config / autoload / {，*。} {global，local} .php'）
）
）; 
  

/config/autoload/env.local.php

 返回数组（
 //允许值：development，staging，live 
'environment'=>'development' 
）; 
  

在一个常见的视图脚本中，我可以通过控制器，因为控制器可以访问服务管理器等所有配置我需要：

 类MyController扩展AbstractActionController {
 
 public function myAction ）{
 return new ViewModel（array（
'currentEnvironment'=> $ this-> getServiceLocator（） - > get（'Config'）['environment']，
） ）; 
} 
 
} 
  

如何在布局视图脚本中访问配置（ / module / Application / view / layout / layout.phtml ）？

解决方案

Crisp的建议：

配置视图助手

 <？php 
 namespace MyNamespace\View\Helper; 
 
使用Zend\View\Helper\AbstractHelper; 
使用Zend\View\HelperPluginManager作为ServiceManager; 
 
类扩展AbstractHelper {
 
 protected $ serviceManager; 
 
 public function __construct（ServiceManager $ serviceManager）{
 $ this-> serviceManager = $ serviceManager; 
} 
 
 public function __invoke（）{
 $ config = $ this-> serviceManager-> getServiceLocator（） - > get（'Config'）; 
 return $ config; 
} 
 
} 
  

$ c>模块 class

  public function getViewHelperConfig（）{
 return array（
'factories'=> array（
'config'=> function（$ serviceManager）{
 $ helper = new \MyNamespace\View\Helper\ Config（$ serviceManager）; 
 return $ helper; 
}，
）
）; 
} 
  

布局视图脚本
$ b

  //使用$ this-> config（）['environment']做任何你想做的事，例如
<？php 
 if（$ this-> config（）['environment'] =='live'）{
 echo $ this-> partial（'partials / partial -foo.phtml'）;; 
} 
？> 
  

I would like / have to manage some settings in ZF1 style and provide the view with the infomation about the current environment.

/config/application.config.php

return array(
    ...
    'module_listener_options' => array(
        ...
        'config_glob_paths' => array('config/autoload/{,*.}{global,local}.php')
    )
);

/config/autoload/env.local.php

return array(
    // allowed values: development, staging, live
    'environment' => 'development'
);

In a common view script I can do it over the controller, since the controllers have access to the Service Manager and so to all configs I need:

class MyController extends AbstractActionController {

    public function myAction() {
        return new ViewModel(array(
            'currentEnvironment' => $this->getServiceLocator()->get('Config')['environment'],
        ));
    }

}

Is it also possible to get the configs in a common view directly?

How can I access the configs in a layout view script (/module/Application/view/layout/layout.phtml)?

解决方案

(My implementation/interpretation of) Crisp's suggestion:

Config view helper

<?php
namespace MyNamespace\View\Helper;

use Zend\View\Helper\AbstractHelper;
use Zend\View\HelperPluginManager as ServiceManager;

class Config extends AbstractHelper {

    protected $serviceManager;

    public function __construct(ServiceManager $serviceManager) {
        $this->serviceManager = $serviceManager;
    }

    public function __invoke() {
        $config = $this->serviceManager->getServiceLocator()->get('Config');
        return $config;
    }

}

Application Module class

public function getViewHelperConfig() {
    return array(
        'factories' => array(
            'config' => function($serviceManager) {
                $helper = new \MyNamespace\View\Helper\Config($serviceManager);
                return $helper;
            },
        )
    );
}

Layout view script

// do whatever you want with $this->config()['environment'], e.g.
<?php
if ($this->config()['environment'] == 'live') {
    echo $this->partial('partials/partial-foo.phtml');;
}
?>
