有效的访问参数 [英] Valid access arguments

问题描述

如何查看有效的访问参数？我看着menu_router，但我相信只给了一些。

How can I look up the valid access arguments? I looked in menu_router, but I believe that only gives some of them.

$items['admin/page'] = array(
   'access arguments' => array('access administration pages'),
  );

推荐答案

其实，你对访问的价值感兴趣访问回调是user_access（默认值）的参数;因为模块可以使用不同的访问回调，访问参数的值在理论上可以是无限的。

Actually, you are interested to the values of the access arguments where the access callback is "user_access" (the default value); as a module can use a different access callback, the values for the access arguments can theoretically be infinite.

调用的所有实现的替代方法hook_permission（）是使用与以下代码相似的代码：

The alternative to invoking all the implementations of hook_permission() is to use code similar to the following one:

$permissions = array();
db_query("SELECT permission FROM {role_permission}");

foreach ($result as $row) {
  $permissions[$row->permission] = TRUE;
}

array_keys（$ permissions）然后会给你所有权限的列表。

array_keys($permissions) will then give you the list of all the permissions.

我从 user_role_permissions（）;不同之处在于该函数对与作为参数传递的角色相关联的权限感兴趣。

I took the query from user_role_permissions(); the difference is that the function is interested in the permissions associated to the role passed as argument.
