如何用php验证mysql中的6位otp

这是我为optverify.php编写的代码，如果输入的数字错误，它将重定向到index.php，它没有给出错误。它应该给出错误otp的错误，但请帮助我解决这个问题

  <?php
 // Create a unique instance of your session variables
session_start();
if(isset($_SESSION['usr_id']))
        {
            $uid=$_SESSION['usr_id'];
        } else {

            header("Location:login.php");
        }
require_once 'include/DB_Functions.php';
    $db = new DB_Functions();

if (isset($_POST['verifyotp'])) {
    $otpsms = $_POST['smsotp'];
    $otpemail = $_POST['emailotp'];

    $user = $db->verifyotp($uid);
    if($user){
        $user['smsotp'] = $otpsms;
        $user['emailotp'] = $otpemail;

    header("Location:index.php");

    } else {

        $errormsg = "Invalid otp";
    }

}

?>

未测试，但这应该可以工作！！如果这不起作用，请告诉我。将删除此答案

已更新

更改此

$user=$db->verifyotp（$uid）至
$user=$db->verifyotp（$uid、$otpsms、$otpemail）

如果您愿意测试3个参数（1）id（2）smsotp（3）emailotp，请修改如下函数

public function verifyotp($uid, $sotp, $eotp){
        $stmt = $this->con->prepare("SELECT uid,smsotp,emailotp FROM users WHERE uid = '$uid' And smsotp='$sotp' And emailotp ='$eotp'");
        $stmt->bind_param("i", $uid);
        if ($stmt->execute()) {
            $stmt->bind_result($uid,$smsotp,$emailotp);
            $stmt->fetch();
            $user = array();
            $user["uid"] = $uid;
            $user["smsotp"] = $smsotp;
            $user["emailotp"] = $emailotp;
            $stmt->close();
            return $user;
     } else 

     {
        return $stmt;
     }

   }

您可以向函数verifyotp（$uid）传递两个参数，比如verifyotp（$uid，$otp）在您的查询中检查相同的内容，以及id使用和条件。能否请您提供一个示例，我有点困惑，因为它不起作用。正在发生相同的事情。在无效OTPT上未给出错误。正在发生相同的事情。在无效otpI上未给出错误。已更新答案。这一行有变化<代码>$user=$db->verifyotp（$uid、$otpsms、$otpemail）
public function verifyotp($uid, $sotp, $eotp){
        $stmt = $this->con->prepare("SELECT uid,smsotp,emailotp FROM users WHERE uid = '$uid' And smsotp='$sotp' And emailotp ='$eotp'");
        $stmt->bind_param("i", $uid);
        if ($stmt->execute()) {
            $stmt->bind_result($uid,$smsotp,$emailotp);
            $stmt->fetch();
            $user = array();
            $user["uid"] = $uid;
            $user["smsotp"] = $smsotp;
            $user["emailotp"] = $emailotp;
            $stmt->close();
            return $user;
     } else 

     {
        return $stmt;
     }

   }
