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。好模板分享给大家：
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 { // ldhost.cn $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！
