我正在浏览我的第一个Drupal模块并提出几个问题。下面的代码是有效的，但肯定是正在进行中的工作。
我想在用户提交表单后推出一个回复页面， 不只是“drupal_set_message”或其他形式，而是整个页面可能显示来自SQL查询的响应
我还想在页面顶部添加一个标签条，以便用户可以在几个类似的选项中进行选择。
感谢您的帮助或建议。

/*
* module: my_first_module_v1.module
*
* This module module allows site users to ask a question
*
* This module uses these Drupal API and functions:
* hook_block - Declare a block or set of blocks.
* hook_help - Provide online user help.
* hook_menu - Define menu items and page callbacks.
* hook_form - Display a node editing form.
* hook_validate - Verify a node editing form.
* hook_submit - This is a hook used by node modules. It is called after validation has succeeded and before insert/update.
* It is used to for actions which must happen only if the node is to be saved. Usually, $node is changed in
* some way and then the actual saving of that change is left for the insert/update hooks.
*
* Again, note that I am pretty new with Drupal, so I can make no guarentees
* as for quality or fitness of code.

关于标签。请参阅Drupal API中的hook_menu。
我们正在寻找： - MENU_LOCAL_TASK：默认情况下，本地任务呈现为制表符。 - MENU_DEFAULT_LOCAL_TASK：每组本地任务都应提供一个“默认”任务，该任务在单击时链接到与其父项相同的路径。
所以它会像
'type' => MENU_DEFAULT_LOCAL_TASK,
其他菜单项将标记为MENU_LOCAL_TASK，请确保它们共享部分路径/部分/路径。 / section / path2等等。
