typo3 - 持久化语言字段

Question

在我的 extbase 模型中，我为字段t3_origuid、sys_language_uid和l10n_parent.

设置这些字段并持久化时，只有l10n_parent字段在数据库中更新。是否可以更改其他字段，而无需手动查询数据库。

Answer 1

要sys_language_uid通过 extbase 进行设置，您需要使用内部 API AbstractDomainObject::_setProperty()，$entity->_setProperty('_languageUid', $languageUid)其中$languageUid将是您的语言记录的 id。您将在 forge 上找到更完整的示例：https ://forge.typo3.org/issues/61722 。

            $columnMap->setChildTableName($dataMap->getTableName());

            $translation->{$propertyName} = $origin;
        }

        $translation->_setProperty('_languageUid', $language);
    }
}

Answer 2

您已经在 TCA 中定义了您的字段。

'sys_language_uid' => array(
    'config' => array(
        'type' => 'passthrough'
    )
)

其他领域也是如此……

网上有一些教程用于将typo3的表与extbase进行映射。

本教程是德语的，但代码不言自明。
