PHP BP_Groups_Member::check_has_invite方法代码示例

/**
 * Check to see whether a user has already been invited to a group.
 *
 * By default, the function checks for invitations that have been sent.
 * Entering 'all' as the $type parameter will return unsent invitations as
 * well (useful to make sure AJAX requests are not duplicated).
 *
 * @param int    $user_id  ID of potential group member.
 * @param int    $group_id ID of potential group.
 * @param string $type     Optional. Use 'sent' to check for sent invites,
 *                         'all' to check for all. Default: 'sent'.
 *
 * @return bool True if an invitation is found, otherwise false.
