【问题描述】:
我在获取 new_grid.phtml 中的属性值时遇到问题。如果我这样做:
<?php $_product = $block->getProduct()
echo $_product->getData('attr_name') ?>
页面生成到这个地方,之后只是空白页面。
请告诉我其他选项,或者我的代码可能有错误。
这里是new_grid.phtml中的地方:
<div class="product-img-block">
<a href="<?php /* @escapeNotVerified */ echo $block->getProductUrl($_item) ?>" class="product-item-photo">
<?php echo $block->getImage($_item, $image)->toHtml(); ?>
/* my code: */
<?php $_product = $block->getProduct() ?>
<img src="<?php echo $_product->getData('attr_name') ?>" />
</a>
这是来自 custom_home.xml 的代码
<container name="header.container" as="header_container" label="Page Header Container" htmlTag="header" htmlClass="page-header" before="main.content"/>
<block class="Magento\Framework\View\Element\Template" name="test_file" template="Magento_Theme::html/front-slider.phtml" before="main.content"/>
<container name="main.content" htmlTag="main" htmlId="maincontent" htmlClass="page-main">
<container name="columns.top" label="Before Main Columns"/>
<container name="columns" htmlTag="div" htmlClass="columns">
<container name="main" label="Main Content Container" htmlTag="div" htmlClass="column main"/>
</container>
</container>
在 front-slider.phtml 中,我通过代码获取 new_grid.phtml:
<?php echo $this->getLayout()->createBlock("Magento\Catalog\Block\Product\Widget\NewWidget")->setDisplayType("all_products")->setProductsCount("6")->setTemplate("product/widget/new/content/new_grid.phtml")->toHtml(); ?>
TBI 答案错误:

关于此代码:
$objectManager = \Magento\Framework\App\ObjectManager::getInstance();
$appState = $objectManager->get('\Magento\Framework\App\State');
$appState->setAreaCode('frontend');
$registry = $objectManager->get('\Magento\Framework\Registry');
$_product= $registry->registry('current_product');
$attribute_code = 'attr_name';
echo $_product->getResource()->getAttribute($attribute_code)-
>getFrontend()->getValue($_product);
