ecshop当前会员等级距离下一等级差多少积分显示

在ecshop上显示ecshop当前会员等级距离下一等级差多少积分，这个功能很实用。最模板分享给大家：

    if ($rank = get_rank_info())    {        $smarty->assign('rank_name', sprintf($_LANG['your_level'], $rank['rank_name']));        if (!empty($rank['next_rank_name']))        {            $smarty->assign('next_rank_name', sprintf($_LANG['next_level'], $rank['next_rank'] ,$rank['next_rank_name']));        }    }

再增加get_rank_info 函数代码

function get_rank_info(){    global $db,$ecs;     if (!empty($_SESSION['user_rank']))    {        $sql = "SELECT rank_name, special_rank FROM " . $ecs->table('user_rank') . " WHERE rank_id = '$_SESSION[user_rank]'";        $row = $db->getRow($sql);        if (empty($row))        {            return array();        }        $rank_name = $row['rank_name'];        if ($row['special_rank'])        {            return array('rank_name'=>$rank_name);        }        else        {          //  zuimoban.com               $user_rank = $db->getOne("SELECT pay_points  FROM " . $ecs->table('users') . " WHERE user_id = '$_SESSION[user_id]'");    $sql = "SELECT rank_name,min_points FROM " . $ecs->table('user_rank') . " WHERE min_points > '$user_rank' ORDER BY min_points ASC LIMIT 1";            $rt  = $db->getRow($sql);            $next_rank_name = $rt['rank_name'];            $next_rank = $rt['min_points'] - $user_rank;            return array('rank_name'=>$rank_name,'next_rank_name'=>$next_rank_name,'next_rank'=>$next_rank);        }    }    else    {        return array();    }} 再在语言库里增加相应的语言中文，插入到模板里next_rank_name  贴这个标签功能就实现了！
