7.27 ECshop 用户 实现 账号 邮箱 手机同时 登录

找到user.php 的以下代码：

if (empty($_POST['captcha']))
{
show_message($_LANG['invalid_captcha'], $_LANG['relogin_lnk'], 'user.php', 'error');
}

　　后面增加：

if(is_email($username))
{
$sql ="select user_name from ".$ecs->table('users')." where email='".$username."'";
$username_e = $db->getOne($sql);
if($username_e) $username=$username_e;
}
if(is_telephone($username))
{
$sql ="select user_name from ".$ecs->table('users')." where mobile_phone='".$username."'";
$username_e = $db->getOne($sql);
if($username_e) $username=$username_e;
}

　　然后在user.php的最底部添加：

function is_telephone($phone){
$chars = "/^13[0-9]{1}[0-9]{8}$|15[0-9]{1}[0-9]{8}$|18[0-9]{1}[0-9]{8}$/";
if (preg_match($chars, $phone)){
return true;
}
}
