你可以用user_load()
and做到这一点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,则有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', $rid);
编辑
如果您想为当前用户执行此操作(就像您在评论中提到的检查的一部分),您可以执行以下操作:
// Check for value over 100.00
if ($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));
}
}
