Php Moodle 2.7需要知道如何为不同的用户组创建自定义菜单

我一直在moodle 2.7框架上工作，我的要求是我想为教师和学生角色显示2个不同的自定义菜单，目前我已经在模板选项中创建了自定义菜单，但我不知道如何在moodle中创建多个自定义菜单。到目前为止，我尝试通过搜索组id，然后使用if语句来分配自定义菜单，但仍然没有输出，因此我请求任何人可以帮助我对这些问题进行排序。

您可以扩展自定义菜单-

然后使用

has_capability（）

查看用户是否可以看到菜单项

像这样的东西（我没试过）

拉塞尔， 下面是renderes.php中的代码

Russell，首先。。非常感谢您抽出时间和提出想法，。。但是让我在我的机器上试试。。。所以我编辑了renderers.php并对其进行了修改，对吗？我今天会试一下，然后再给你回复。好的，我想展示一下下面的菜单。示例：教师菜单：主页|课程|课程|日历|报告学生菜单：主页|课程|课程|课程|简介|请让我知道如何从您给定的代码中执行此操作。嗨，我在moodle上真的看不到太多信息，只是为了为用户创建多个菜单，我们正在努力实现，但没有输出。。我认为moodle不是一个好的框架……嗨，有人能告诉我如何根据用户角色隐藏一些菜单项吗，例如，如果我有教师菜单1 |菜单2 |菜单3 |菜单4的菜单项，我喜欢在学生角色中隐藏菜单3 |菜单4。
