我有实现 hook_nodeapi() 的 drupal 6 模块。我必须将其转换为 drupal 7。需要建议。任何帮助都会很棒。
- “alter”：$node->content 数组已被渲染，因此节点主体或预告片被过滤，现在包含 HTML。仅当需要文本替换、过滤或其他原始文本操作时才应使用此操作。
- “delete”：正在删除节点。
- “delete revision”：节点的版本被删除。您可以删除与该修订相关的数据。
- “插入”：节点刚刚被创建（插入到数据库中）。
- “load”：节点即将从数据库中加载。这个钩子此时可以用来加载额外的数据。
- “准备”：节点即将显示在添加/编辑表单上。
- “准备翻译”：正在克隆节点以进行翻译。从 $node->translation_source 加载附加数据或复制值。
- “print”：准备一个节点视图进行打印。用于 book_module 中的打印机友好视图
- “rss item”：生成一个 RSS 提要。该模块可以返回要添加到为此节点生成的 RSS 项的属性。有关示例，请参见 comment_nodeapi() 和 upload_nodeapi()。还可以修改传递的 $node 以向提要项添加或删除内容。
- “搜索结果”：节点显示为搜索结果。如果您想在结果中显示额外信息，请将其返回。
- “presave”：节点通过验证，即将被保存。模块可以使用它在节点保存到数据库之前对其进行更改。
- “update”：该节点刚刚在数据库中更新。
- “更新索引”：正在索引节点。如果您希望通过nodeapi“视图”对其他信息进行索引，那么您应该在此处返回它。
- “验证”：用户刚刚完成编辑节点并尝试预览或提交。这个钩子可以用来检查节点数据。应使用 form_set_error() 设置错误。
"view"：渲染前正在组装节点内容。该模块可以在渲染之前添加元素 $node->content 。这个钩子会在 hook_view() 之后被调用。$node->content 的格式与 Forms API 使用的格式相同。
