phtml magento 2에서 루트 디렉토리 경로를 얻는 방법은 무엇입니까?

$objectManager = \Magento\Framework\App\ObjectManager::getInstance();

$storeManager = $objectManager->get('\Magento\Store\Model\StoreManagerInterface');

$mediaPath  =   $fileSystem->getDirectoryRead(\Magento\Framework\App\Filesystem\DirectoryList::MEDIA)->getAbsolutePath();

미디어 경로를 반환합니다. phtml 페이지에서 프로젝트의 루트 경로를 얻는 방법은 무엇입니까?

\ Magento \ Framework \ Filesystem \ DirectoryList 클래스 는 루트, 미디어, var 등의 경로를 얻는 데 사용됩니다.

이것은 다음과 같이 프로젝트의 루트 디렉토리를 얻을 것입니다

/ var / www / html / myproject

ObjectManager 작성

$objectManager = \Magento\Framework\App\ObjectManager::getInstance();

$directory = $objectManager->get('\Magento\Framework\Filesystem\DirectoryList');

echo $rootPath  =  $directory->getRoot();

의존성 주입으로

protected $_dir;
...

public function __construct(
    ...
    \Magento\Framework\Filesystem\DirectoryList $dir,
    ...        
) {
    ...
    $this->_dir = $dir;
    ...
}

같은 다른 디렉토리 경로 가져 오기

$this->_dir->getRoot(); // Output: /var/www/html/myproject

$this->_dir->getPath('media'); // Output: /var/www/html/myproject/pub/media

$this->_dir->getPath('pub'); // Output: /var/www/html/myproject/pub

$this->_dir->getPath('static'); // Output: /var/www/html/myproject/pub/static

$this->_dir->getPath('var'); // Output: /var/www/html/myproject/var

$this->_dir->getPath('app'); // Output: /var/www/html/myproject/app

$this->_dir->getPath('etc'); // Output: /var/www/html/myproject/app/etc

$this->_dir->getPath('lib_internal'); // Output: /var/www/html/myproject/lib/internal

$this->_dir->getPath('lib_web'); // Output: /var/www/html/myproject/lib/web

$this->_dir->getPath('tmp'); // Output: /var/www/html/myproject/var/tmp

$this->_dir->getPath('cache'); // Output: /var/www/html/myproject/var/cache

$this->_dir->getPath('log'); // Output: /var/www/html/myproject/var/log

$this->_dir->getPath('session'); // Output: /var/www/html/myproject/var/session

$this->_dir->getPath('setup'); // Output: /var/www/html/myproject/setup/src

$this->_dir->getPath('di'); // Output: /var/www/html/myproject/var/di

$this->_dir->getPath('upload'); // Output: /var/www/html/myproject/pub/media/upload

$this->_dir->getPath('generation'); // Output: /var/www/html/myproject/var/generation

$this->_dir->getPath('view_preprocessed'); // Output: /var/www/html/myproject/var/view_preprocessed

$this->_dir->getPath('composer_home'); // Output: /var/www/html/myproject/var/composer_home

$this->_dir->getPath('html'); // Output: /var/www/html/myproject/var/view_preprocessed/html

참고 : 당신은 사용해서는 안 \Magento\Framework\App\ObjectManager::getInstance() 그것은 의존성 주입의 목적을 패배.

magento 2 기본 변수를 사용하여 Magento 디렉토리의 절대 경로를 얻을 수 있습니다

echo BP;

루트 디렉토리를 얻으려면 ROOT 를 사용해야합니다

$objectManager = \Magento\Framework\App\ObjectManager::getInstance();

$storeManager = $objectManager->get('\Magento\Store\Model\StoreManagerInterface');
$fileSystem = $objectManager->get('Magento\Framework\Filesystem');
$mediaPath  =   $fileSystem->getDirectoryRead(\Magento\Framework\App\Filesystem\DirectoryList::ROOT)->getAbsolutePat‌​h()

Alan Storm의 접근 방식을 선호합니다 .

$object_manager = MagentoCoreModelObjectManager::getInstance();
$dir = $object_manager->get('MagentoAppDir');            
$base = $dir->getDir();
$media = $dir->getUrl(MagentoAppDir::MEDIA);
