发票电子邮件模板中的产品图片

我正在尝试获取发票电子邮件模板的产品图像。我用下面的代码。但是我在电子邮件模板中只得到了Magento占位符图像。

<td>
    <?php 
    $objectManager = \Magento\Framework\App\ObjectManager::getInstance();
    $product_id = $_item->getOrderItem()->getProduct();
    $product = $objectManager->get('Magento\Catalog\Model\Product')->load($product_id);

    $_imagehelper = $objectManager->get('Magento\Catalog\Helper\Image');
    $image_url = $_imagehelper->init($product, 'cart_page_product_thumbnail')->getUrl();

    ?>
      <img src="<?php echo $image_url; ?>" alt="<?php echo $product->getName(); ?>" />
</td>

我找到了解决方案，但它正在获取父缩略图，我想获取是否已在色板选项中选择了产品，该色板选项需要显示。

例如：如果我选择红色，则需要显示红色色板图像。

$productId = $_item->getProductId();
$objectManagerHere = \Magento\Framework\App\ObjectManager::getInstance();
$product = $objectManagerHere->get('Magento\Catalog\Model\Product')->load($productId);

$_objectManager = \Magento\Framework\App\ObjectManager::getInstance();
$imageHelper  = $_objectManager->get('\Magento\Catalog\Helper\Image');
$image_url = $imageHelper->init($product, 'product_thumbnail_image')->setImageFile($product->getFile())->resize(80, 80)->getUrl();

<img src="<?php echo $image_url; ?>" alt="<?php echo $product->getName(); ?>" />

我有覆盖 DefaultInvoice

        if ($options) {
            foreach ($options as $option) {
                // draw options label
                $lines[][] = [
                    'text' => $this->string->split($this->filterManager->stripTags($option['label']), 40, true, true),
                    'font' => 'italic',
                    'feed' => 35,

                    }
                    $values = explode(', ', $printValue);
                    foreach ($values as $value) {
                        $lines[][] = ['text' => $this->string->split($value, 30, true, true), 'feed' => 40];
                    }
                }
            }
        }

        $lineBlock = ['lines' => $lines, 'height' => 20];

        $page = $pdf->drawLineBlocks($page, [$lineBlock], ['table_header' => true],1);

        $this->setPage($page);
    }


    /*
     * Return Value of custom attribute
     * */
    private function getProductImage($item,  &$page)
    {
        $objectManager = \Magento\Framework\App\ObjectManager::getInstance();
        $productId = $item->getOrderItem()->getProductId();
        $image = $objectManager->get('Magento\Catalog\Model\Product')->load($productId);

        if (!is_null($image)) {
            try{

                $imagePath = '/catalog/product/'.$image->getSmallImage();

                $filesystem = $objectManager->get('Magento\Framework\Filesystem');
                $media_dir = $filesystem->getDirectoryRead(\Magento\Framework\App\Filesystem\DirectoryList::MEDIA);

                if ($media_dir->isFile($imagePath)) {
                    return $media_dir->getAbsolutePath($imagePath);
                }
                else
                    return null;
            }
            catch (Exception $e) {
                return false;
            }
        }
    }
}

这样返回我的PDF。（致力于图像旋转：））

这是基于配置产品的变体选择的发票中的简单产品图像。

更多参考

参考文献1，参考文献2，参考文献3

您可以在代码中替换以下行

$product = $objectManagerHere->get('Magento\Catalog\Model\Product')->load($productId);

与以下行

$product = $objectManagerHere->get('Magento\Catalog\Model\ProductRepository')->get($_item->getSku());

这样，您可以获得可配置产品的适当简单产品。

我认为您应该尝试使用，cart_page_product_thumbnail而不是product_thumbnail_image在获取产品图片代码中使用。

您的代码应如下所示。

$image_url = $imageHelper->init($product, 'cart_page_product_thumbnail')->setImageFile($product->getFile())->resize(80, 80)->getUrl();

我已使用上面的代码在“电子邮件”模板中显示产品图片，并且可与可配置产品配合使用。而且我认为它也适用于发票电子邮件模板。

我也看到这么多用户使用，cart_page_product_thumbnail请检查下面的参考链接。

• 产品图片新订单电子邮件
• 在销售订单视图页面中显示产品图像

希望对您有所帮助！
