在 new_grid.phtml magento 中获取产品属性值

Question

我在 new_grid.phtml 中获取属性值时遇到问题。如果我这样做：

<?php $_product = $block->getProduct()
echo $_product->getData('attr_name') ?>

页面生成到这个地方，之后就是空白页。

请告诉我其他选项，或者我的代码有错误。

这是new_grid.phtml中的位置：

<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>

代码来自custom_home.xml

<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>

前面-slider.phtml 我通过代码得到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(); ?>

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);

Answer 1

首先，请验证您是否已将自定义属性添加到正确的属性集中，并将该属性集分配给您为其添加此代码的产品，然后最后使用以下代码获取其值。

$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);

谢谢

Answer 2

getResource()->getAttribute($attribute_code)->getFrontend()->getValue($_item);
?>

Answer 3

$_product = $block->getProduct();
print_r($_product->getData);

首先你需要检查产品数据是否可用，如果你有正确的数组，那么你只需要从下面的代码中调用产品属性。

echo  $_product->getResource()->getAttribute('ATTRIBUTE_CODE')->getFrontend()->getValue($_product);

Answer 4

$productModel = Mage::getModel('catalog/product');
$_product = $productModel->load(42); // Add your product ID
$attribute_code = 'attr_name'; // Add your attribute name
echo  $_product->getResource()->getAttribute($attribute_code)->getFrontend()->getValue($_product);

根据您上面的评论，请试试这个，只需更改我上面提到的产品 ID 和属性代码

Answer 5

我觉得产品对象在您的代码中不可用。仅在当前产品的产品视图页面上的产品对象。在其他页面上您必须创建。

Answer 6

尝试根据您的代码修改此代码

    @var $block \Magento\Catalog\Block\Product\Widget\NewWidget 
    if ($exist = ($block->getProductCollection() 
    && $block->getProductCollection()->getSize())) 
    {
        $items = $block->getProductCollection()->getItems();
    }
    <?php foreach ($items as $_item): ?>
        <img src="<?php echo $_item->getData("nameofattribute") ?>" />
    <?php endforeach ?>

如果您不知道属性的名称，您可以使用 $_item->getData() 并获取当前项目的所有列表数据。

在 new_grid.phtml magento 中获取产品属性值
