ecshop充值满100送10元红包的代码怎么写啊？具体点的，ecshop新手求助

在user.php 的注册成功信息显示前面，大概是 show_message(sprintf($_LANG['register_success'].............前面加入
注意下下面的 $bonus_type_id = 1; 需要先在后台加入对应的红包的id
//phpsir 1111
$bonus_type_id=1;
$bonus = $db->getRow('SELECT * FROM ' . $ecs->table("bonus_type") . " WHERE send_type = 0 And type_id = $bonus_type_id", true);
if($bonus){ if(time()<($bonus['send_end_date']+28800)){
$sql = "INSERT INTO " . $ecs->table('user_bonus') . "(bonus_type_id, bonus_sn, user_id, used_time, order_id, emailed) " . "VALUES ('$bonus[type_id]', 0, '$_SESSION[user_id]', 0, 0, 0)";
$db->query($sql); } }
//phpsir 1111_end
