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！
