修改前：
$_LANG['send_by'][SEND_BY_USER] = '按用户发放';$_LANG['send_by'][SEND_BY_GOODS] = '按商品发放';$_LANG['send_by'][SEND_BY_ORDER] = '按订单金额发放';$_LANG['send_by'][SEND_BY_PRINT] = '线下发放的红包';

修改后：
$_LANG['send_by'][SEND_BY_SIGN] = '注册就送';
$_LANG['send_by'][SEND_BY_LOGIN] = '登录就送';
$_LANG['send_by'][SEND_BY_MANUAL] = '手动发送';
$_LANG['send_by'][SEND_BY_USER] = '用户领取';
$_LANG['send_by'][SEND_BY_AUTO] = '自动发送';

红包页面报错：
