我有drupal 6模块，它实现了hook_nodeapi（）。我必须将其转换为drupal 7.需要建议。任何帮助都会很棒。
“view”：在渲染之前正在组装节点内容。模块可以在渲染之前添加元素$ node-＆gt;内容。这个钩子将在hook_view（）之后调用。 $ node-＆gt;内容的格式与Forms API使用的格式相同。

答案 0 :(得分：1)
已弃用hook_node_load()，hook_node_view()，hook_node_insert()，hook_node_presave()，hook_node_update()作为hook_nodeapi()。还必须根据drupal 7面向对象的查询strusture更改相关查询。
解决了问题。
