以编程方式将标签添加到 Joomla

Question

我需要将大约 600 个标签从旧项目迁移到 Joomla，并希望以编程方式进行。我已经看过但没有找到任何关于如何实现这一目标的提示。我发现了一些关于如何以编程方式为文章添加标签的建议（稍后可能会派上用场，但首先我需要拥有这些标签）。我想过直接通过数据库查询来做，但 Joomla 坚持在任何地方都使用嵌套表（标签表有一个 lft 和 rgt 行）。我可以安全地忽略这些，还是它会在某个地方破坏系统？

提前感谢您的帮助。

这是我拥有的 CLI，它读取 csv 文件并从中创建标签。通过使用 API，store() 将创建正确的嵌套数据。这非常粗糙，因为它只是用于测试标签 api/性能，因此您可能需要清理它，特别是如果您有其他数据要放入 csv（或不同的数据源）。更新：它也有点旧，所以你可能需要导入 cms 和遗留库，因为在 3.2 中对 store() 进行了更改。这是 docs wiki 中关于为什么 CLI 应用程序在 3.2 中中断的内容，您应该查看。

Answer 2

如果您想使用结构标签，只需取消注释此行：

$table->setLocation(parent_id, 'last-child');

where parent_id - 父标签节点的id
