这让我发疯,我创建了一个带有助手的模块:
namespace MyNamespace\MyModule\Helper;
class Data extends \Magento\Framework\App\Helper\AbstractHelper
{
protected $registry;
public function __construct
(
\Magento\Framework\Registry $registry,
\Magento\Eav\Api\AttributeSetRepositoryInterface $attributeSet
) {
$this->registry = $registry;
$this->attributeSet = $attributeSet;
}
public function getTitle()
{
$this->product = $this->registry->registry('product');
$product_name = $this->product->getName();
$attributeSetRepository = $this->attributeSet->get($this->product->getAttributeSetId());
if ($attributeSetRepository->getAttributeSetName() == "Default Engine Component"){
$engine = $this->product->getAttributeText('engine_select');
if (!is_array($engine)){
return "$engine $product_name";
}
}
return $product_name;
}
}
......这可以正常工作。然后我将以下内容添加到:
/app/design/frontend/vendor/theme/Magento_Catalog/layout/catalog_product_view.xml
<referenceBlock name="page.main.title">
<action method="setPageTitle">
<argument name="title" xsi:type="helper" helper="MyNamespace\MyModule\Helper\Data::getTitle"></argument>
</action>
</referenceBlock>
...但它在产品页面上没有任何改变。我知道它被调用了,因为我可以回显变量并且它们显示在页面顶部,但似乎 XML 并没有像我希望的那样做。
有人有什么想法吗?
