- “alter”:已经呈现了$node->content数组,因此节点主体或摘要被过滤,现在包含HTML。仅当需要文本替换、筛选或其他原始文本操作时,才应使用此op
- “删除”:正在删除节点
- “删除修订”:删除节点的修订。您可以删除与该修订相关联的数据
- “插入”:节点刚刚创建(插入到数据库中)
- “加载”:即将从数据库加载节点。这个钩子可以用来加载额外的数据
- “准备”:节点将显示在添加/编辑表单上
- “准备翻译”:正在克隆节点以进行翻译。从$node->translation\u source加载其他数据或复制值
- “打印”:准备要打印的节点视图。用于book_模块中的打印机友好视图
- “rss项目”:生成rss提要。模块可以返回要添加到此节点生成的RSS项的属性。有关示例,请参见注释和上传。 还可以修改传递的$node以向提要项添加或删除内容
- “搜索结果”:节点显示为搜索结果。如果要显示结果的额外信息,请返回它
- “presave”:节点已通过验证,即将保存。在将节点保存到数据库之前,模块可以使用此选项对节点进行更改
- “更新”:该节点刚刚在数据库中更新
- “更新索引”:正在索引节点。如果您希望索引其他信息,而这些信息在nodeapi“视图”中尚不可见,则应在此处返回
- “验证”:用户刚刚完成对节点的编辑,正在尝试预览或提交节点。这个钩子可以用来检查节点数据。错误应使用表单\u set\u error()设置
- “视图”:渲染前正在组装节点内容。模块可以在渲染之前添加元素$node->content。此挂钩将在hook_view()之后调用。$node->content的格式与Forms API使用的格式相同
