自定义菜单帮助
Drupal 7 hook_menu() 让我很困惑；我已经尝试了一切，但似乎无法让它发挥作用。
我需要什么：在自定义模块中，我想创建一个新菜单，并向该菜单添加大约四个链接。听起来很简单，但我很挣扎。我已经能够使用 .install 文件中的 $menu 数组创建菜单本身，但向该菜单添加项目没有意义。
有效代码：
$menu = array(
'menu_name' => 'project-menu',
'title' => $t('Project Menu'),
'description' => 'Project Menu',
);
menu_save($menu);
无效代码：
$items = array();
$items['project-menu/%'] = array(
'title' => 'Test Link',
'page callback' => 'dc_project_page',
'page arguments' => array(1),
'access callback' => TRUE,
'type' => MENU_LOCAL_TASK,
);
return $items;
这些全部位于 dc_project.install 文件中的 dc_project_menu() 函数下。希望我只是做了一些愚蠢的事情，非常感谢任何和所有的帮助。即使只是向我指出一个可以干净地完成此操作的模块作为示例，谢谢。我确实查看了示例项目，但无法获得任何内容，无法将链接添加到我的新菜单工作。
Drupal 7 hook_menu() is confusing me; I have tried everything and I can't seem to get this to work.
What I need: In a custom module, I'd like to create a new menu, and add about four links to that menu. It sounds simple, but I am struggling. I've been able to create the menu itself using the $menu array in the .install file, but adding items to that menu doesn't make sense.
Code that is working:
$menu = array(
'menu_name' => 'project-menu',
'title' => $t('Project Menu'),
'description' => 'Project Menu',
);
menu_save($menu);
Code that isn't working:
$items = array();
$items['project-menu/%'] = array(
'title' => 'Test Link',
'page callback' => 'dc_project_page',
'page arguments' => array(1),
'access callback' => TRUE,
'type' => MENU_LOCAL_TASK,
);
return $items;
This is all in the dc_project.install file under the dc_project_menu() function. Hopefully I'm just doing something stupid, any and all help is extremely appreciated. Even just pointing to me to a module that does this cleanly as an example, thanks. I did look at the example project, haven't been able to get anything as far as adding links to my new menu working.

传递到 menu_save()
$items的内容不起作用，因为menu_save()只接受包含menu_name的数组，标题和描述。$items中使用的是一个描述模块实现的菜单回调的数组，所有模块实现的菜单回调的定义并不保存在“menu_custom”中（< code>menu_save()），但缓存在 Drupal 缓存表中。如果您尝试更改另一个模块定义的菜单回调，那么您应该实现 hook_menu_alter();否则，如果您只想定义模块的菜单回调，则应该实现 hook_menu()。
两个钩子实现（
hook_menu()和hook_menu_alter()）都必须位于模块文件中（在您的情况下，位于 dc_project.module 中），而不是位于 dc_project.install 中。 Drupal在正常加载启用的模块时不会加载安装文件；它会在更新（或安装）模块时加载安装文件，但在其他情况下不会加载它。用
menu_save()保存菜单的代码可以在安装文件中，在hook_install() 或 hook_update_N()。它也可以放入Passing to menu_save() the content of
$itemsdoesn't work becausemenu_save()accepts only an array containingmenu_name,title, anddescription.What you use in
$itemsis an array describing the menu callbacks implemented by a module, and the definitions of the menu callbacks implemented by all the modules are not saved in "menu_custom" (the table used frommenu_save()) but are cached in a Drupal cache table.If you are trying to change the menu callbacks defined by another module, then you should implement hook_menu_alter(); otherwise, if you just want do define the menu callbacks of your module, you should implement hook_menu().
Both the hooks implementations (
hook_menu()andhook_menu_alter()) must be in the module file (in your case, in dc_project.module), not in dc_project.install. Drupal doesn't load the installation file when it normally loads the enabled modules; it loads the installation file when a module is being updated (or installed), but it doesn't load it in other cases.The code that saves the menu with
menu_save()can be in the installation file, in the implementation of hook_install() or hook_update_N(). It could also be put in the implementation of hook_enable(); in that case, the code (which is executed when the module is enabled) should first verify the menu has not been already added. (hook_enable()andhook_disable()should be placed in the installation file.)
