Answer 1

你永远不应该使用ObjectManager.

你可以将它放在Block中,并getCategoryName()在phtml中调用该函数:

namespace Company\Module\Block;

class CustomBlock extends \Magento\Framework\View\Element\Template 
{
    protected $_categoryFactory;    

    public function __construct(
    \Magento\Catalog\Model\CategoryFactory $categoryFactory,
    \Magento\Framework\View\Element\Template\Context $context,
    ) {
        $this->_categoryFactory = $categoryFactory;
        parent::__construct($context);
    }

    public function getCategoryName()
    {
        $categoryId = '43';
        $category = $this->_categoryFactory->create()->load($categoryId);
        $categoryName = $category->getName();
        return $categoryName;
    }
}

尝试使用以下代码获取Magento2中的Category对象:

$categoryId = 3;
$_objectManager = \Magento\Framework\App\ObjectManager::getInstance();
$category = $_objectManager->create('Magento\Catalog\Model\Category')
->load($categoryId);
echo $category->getName();
