如何在Drupal中分配PHP角色？

问题描述

我需要为通过PHP购买金额等于或大于100欧元的会员指定一种溢价状态。

I need to assign a kind of "premium status" to members that purchase an amount equal or greater than 100 € via PHP.

条件操作已设置完毕（用户=匿名/验证和总金额=等于/大于100 AND用户=！溢价）但我缺少PHP部分实际上说然后授予他高级会员资格。

Conditional Actions are already set up (user = anonymous/authenticated AND total amount = equal/greater than 100 AND user =! premium) but I'm missing the PHP part to actually say "then grant him the premium membership".

如何实现？

编辑：以下代码是否正确？

is the below code correct?

if ($account) {
  $uid = $account->uid;
  $role_name = 'authenticated user';
  $rid = db_result(db_query("SELECT rid FROM {role} WHERE name = '%s'", $role_name));
  db_query("INSERT INTO {users_roles} (uid, rid) VALUES(%d, %d)", $uid, $rid);
  watchdog('user', 'uc ca added role to Ubercart created user');
}

推荐答案

a href =http://api.drupal.org/api/function/user_load/6 =nofollow noreferrer> user_load（） 和 ：

You can do this with user_load() and user_save():

$uid = 1; // UID of user to add role to
$role_name = 'test role'; // Name of role to add

// Get RID of role
$rid = db_result(db_query("SELECT r.rid FROM {role} r WHERE r.name = '%s'", $role_name));

// Load user object
$account = user_load(array('uid' => 1));

// Save the user object with the new roles.
if ($account !== FALSE && !isset($account->roles[$rid])) {
  $roles = $account->roles + array($rid => $role_name);
  user_save($account, array('roles' => $roles));
}

如果您希望批量处理多个用户， =http://api.drupal.org/api/function/user_multiple_role_edit/6 =nofollow noreferrer> user_multiple_role_edit（） ：

If you wanted to do this in bulk for multiple users, there's user_multiple_role_edit():

$uids = array(1, 2, 3, 4); // UIDs of users to add role to
$role_name = 'test role'; // Name of role to add

// Get RID of role
$rid = db_result(db_query("SELECT r.rid FROM {role} r WHERE r.name = '%s'", $role_name));

// Add the role to UIDs
user_multiple_role_edit($uids, 'add_role', $rid);

如果你想为当前用户执行此操作（例如注释中提到的检查的一部分），可以这样做：

Edit

If you wanted to do this for the current user (like part of the check you mentioned in a comment), you can do:

// Check for value over 100.00
if ($total_value > 100) {
  global $user; // Retrieve user object for currently logged in user.

  $role_name = 'test role'; // Name of role to add

  // Get RID of role
  $rid = db_result(db_query("SELECT r.rid FROM {role} r WHERE r.name = '%s'", $role_name));

  // Save the user object with the new role.
  if (!isset($user->roles[$rid])) {
    $roles = $user->roles + array($rid => $role_name);
    user_save($user, array('roles' => $roles));
  }
}
// Other code here.
