我正在做一个表单，其中reset.php中的密码正在恢复。我已经根据恢复邮件输入后的密码进行了编程。但是障碍只是一个小错误，单击更改密码按钮后不显示任何消息。注意* =即使更改了if..else..，密码也会更改，但仅不会显示错误/成功消息。

这是forgot.php的代码(可以完美工作并链接到reset.php)

<?php

    ob_start();
    session_start();
    include('db-config.php');

    if(isset($_POST['forgot-submit'])){
        $recovery_user = $_POST['forgot-email'];
        $query = "SELECT * FROM RegisteredMembers WHERE userEmail='$recovery_user'";
        $output = mysql_query($query);
        $count = mysql_num_rows($output);
        $row = mysql_fetch_array($output);
        if($count==1){
            $error = false;

            // Mail the Recovery link
            $recovery_code = md5(uniqid(rand()));
            $mTo = $recovery_user;
            $mFrom = 'From: '.$website_details['name'].' Team '.'<'.$website_details['email'].'>';
            $mSubject = $website_details['name']." Account recovery Mail";
                // Message
                $mMsg[0] = "Hi ".$row['fname'].", \r\n";
                $mMsg[1] = "This is the password recovery email which you have requested just few minutes before. <b>(If you havn't requested, you may kindly ingnore this Email)</b>";
                $mMsg[2] = "Here's your <a href='$web_path/reset.php?recoverykey=$recovery_code'>Password Recovery Link</a>. Clicking it would allow you to change your existing password into a new one.";
                $mFinMsg = $mMsg[0].$mMsg[1].$mMsg[2];
            $sendRecMail = mail( $mTo , $mSubject , $mFinMsg , $mFrom );

            // Add recovery code to Database
            $mysql = "UPDATE RegisteredMembers SET RecoveryCode='$recovery_code' WHERE userEmail='$recovery_user'";
            $result = mysql_query($mysql);
            if($result){
                $error = false;
                $forgotEmailMsg = "Thanks, Check your Email for recovering your password.";
            } else{
                echo "Looks like there's a Disturbance and Load on server. Try again later.";
            }
        } else if(strlen($recovery_user)==0){
            $error = true;
            $forgotEmailMsg = "Please do not leave this field empty.";
        } else{
            $error = true;
            $forgotEmailMsg = "No such Email found in Database.";
        }
    }

这是 reset.php的代码。 (这是实际问题仍然存在的页面)

即使设置了“新密码”和“确认密码错误/成功”消息，但是单击 更改密码按钮后也看不到任何消息。 (仅密码更改)

尚无CSS样式。因此，他们没有办法解决 display:none的CSS问题。

实际问题-我希望正确回显变量 $passError和 $Con_passError。

预先感谢您提供的帮助!
