【问题标题】:Get product attribute value in new_grid.phtml magento在 new_grid.phtml magento 中获取产品属性值
【发布时间】:2018-03-27 02:32:38
【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);

    【解决方案1】:

    尝试将此代码适应您的代码

        @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 ?>
    

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

    【讨论】:

      【解决方案2】:

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

      【讨论】:

      • 在其他页面上您必须创建。 - 如何?
      【解决方案3】:

      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要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

      【讨论】:

      • 是的,我的产品处于默认属性集中,您的代码得到:异常 #0(异常):注意:未定义变量:/chroot/home/autospar/domain.com/html/app 中的 _product /design/frontend/central/central-theme/Magento_Catalog/templates/product/widget/new/content/new_grid.phtml 在第 50 行
      • 我已经更新了上面的代码,请检查一次。它应该可以解决您的问题谢谢
      • 在 cmets 中我无法向大家展示,我有更新问题:1 个异常:异常 #0 (Magento\Framework\Exception\LocalizedException):区号已设置异常 #0 (Magento \Framework\Exception\LocalizedException): 区号已设置
      【解决方案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,请尝试一下,只需更改我上面提到的产品 ID 和属性代码

      【讨论】:

      • 页面生成到这个地方,之后只是空白页面,页面丢失样式。
      【解决方案5】:
      $_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);
      

      【讨论】:

      • 当我想通过您的代码“$_product = $block->getProduct(); print_r($_product->getData);”进行检查时我得到这个:1个异常:异常#0(异常):注意:试图在/chroot/home/autospar/domain.com/html/app/design/frontend/central/central中获取非对象的属性-theme/Magento_Catalog/templates/product/widget/new/content/new_grid.phtml 第 50 行
      【解决方案6】:
      getResource()->getAttribute($attribute_code)->getFrontend()->getValue($_item);
      ?>

      【讨论】:

      • 如何获得 attr 之一?像这样: getResource()->getAttribute($attribute_code)->getFrontend()->getValue($_product); ?>
