Magento 2의 카테고리 페이지에 맞춤 표준 URL 표시

Aug 16 2020

사용자 지정 범주 속성 (사용자 지정 표준 URL)을 범주 페이지에 추가하는 모듈을 만들었습니다. 속성은 관리자에 표시되며 값을 저장할 수 있습니다. _prepareLayout()기능을 확장 \Magento\Catalog\Block\Category\View했지만 작동하지 않는 것 같습니다. 내가 뭔가를 놓치고 있거나 더 나은 방법이 있습니까?

이제 다음과 같이 변경하여 작동합니다.

만들어진 Example/CategoryCanonicalUrl/etc/di.xml

<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:ObjectManager/etc/config.xsd">
    <preference for="Magento\Catalog\Block\Category\View" type="Example\CategoryCanonicalUrl\Block\Category\CanonicalUrl"/>
</config>

아래에 추가 Example/CategoryCanonicalUrl/etc/module.xml

        <sequence>
            <module name="Magento_Catalog"/>
        </sequence>

조정 에 에 내가 점점되면서 오류가 발생했습니다.parent::__construct($context, $data);parent::__construct($context, $layerResolver, $registry, $categoryHelper, $data);Example/CategoryCanonicalUrl/Block/Category/CanonicalUrl.phpType Error occurred when creating object

제거 parent::_prepareLayout();에서 protected function _prepareLayout()의 Example/CategoryCanonicalUrl/Block/Category/CanonicalUrl.php나는 정식 링크 태그를 중복지고 있었다한다.

Example/CategoryCanonicalUrl/Block/Category/CanonicalUrl.php예를 들어 관리 영역 example-category의 Custom Canonical URL입력을 통해 추가되는 경우 전체 표준 URL 에 대해 매장 관리자를 추가했습니다 .
