如何在Drupal中使用PHP分配角色？

Question

我需要为通过PHP购买金额等于或大于100欧元的会员分配一种"高级状态".

已经设置了条件操作(user =匿名/已验证且总金额=等于/大于100 AND user =!premium)但我错过了PHP部分实际说"然后授予他高级会员资格".

我怎样才能做到这一点？

编辑:以下代码是否正确？

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');
}

你可以用user_load()和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));
}

如果您想为多个用户批量执行此操作,请执行以下操作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);

如果您想为当前用户执行此操作(例如您在评论中提到的检查的一部分),您可以执行以下操作:

// 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));
  }
}
