子比限制白名单的邮箱才能注册本站

代码加到action/function.php 50行左右

//邮箱白名单
function match_email($mail){
    $domain=array(1=>"@qq.com", "@163.com", "@139.com", "@vip.qq.com", "@sohu.com", "@sohu.com", "@gmail.com", "@gmail.com", "@foxmail.com", "@outlook.com");
    foreach ($domain as $k=>$v){
        if($k==count($domain)){
            if(!preg_match("/".$domain[$k]."/", $mail)){
                return 1;
            }
            else{return 0;}
        }
        if(preg_match("/".$domain[$k]."/", $mail)){return 0;}
        else{continue;}
    }
}

代码加到同一文件发送验证码函数中，位置如图

if(match_email($to)){return array('error' => 1, 'ys' => 'danger', 'msg' => '本站只允许使用QQ、163等邮箱登陆注册，具体请查看用户注册协议');};
