以PHP形式顯示錯誤消息
[英]Display an Error Message in PHP form
問題描述
我一直在做一個表單，其中的密碼正在reset.php中恢復。 我已經根據恢復郵件輸入后的密碼進行了編程。但是障礙只是一個小錯誤，單擊“ 更改密碼”按鈕后不顯示任何消息。 注意* =即使更改了if..else.. ，密碼也會更改，但僅不會顯示錯誤/成功消息。
這是forgot.php的代碼（可以完美運行並鏈接到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; $forgotEmailMsg = "No such Email found in Database."; } } ?> <!DOCTYPE html> <html> <head> <meta name="robots" content="noindex" /> <link rel="stylesheet" type="text/css" href="assets/scripts/css/styles.css" /> <title>Password Recovery</title> </head> <body> <form class="iqform" method="post" action="<?php echo htmlspecialchars($_SERVER['PHP_SELF']); ?>" autocomplete="off"> <h3>Password Recovery</h3> <label><span class="text-danger"><?php echo $forgotEmailMsg; ?></span><input type="email" placeholder="Your registered Email" name="forgot-email" required /></label> <input type="submit" value="Next" name="forgot-submit" /> </form> </body> </html> <?php ob_end_flush(); ?>
這是reset.php的代碼。 （這是實際問題仍然存在的頁面）

Feel free to Log In."; $zero = 0; $sql2 = "UPDATE RegisteredMembers SET RecoveryCode = '$zero' WHERE RecoveryCode = '$recovery_code'"; $output2 = mysql_query($sql2); if($output2==1){ $error = false; } } } } else if(!($pass==$Con_pass)){ $error = true; $Con_passError = "The Password isn't matching. Be sure you remember the New Password."; } else if(empty($pass)){ $error = true; $passError = "Please do not keep the password empty."; } else if(empty($Con_pass)){ $error = true; $Con_passError = "Please do not keep this field empty."; } } /*date_default_timezone_set("America/New_York"); $nowtime = date("h:i:sa"); $endtimestamp = mktime(date("H"),date("i")+1,date("s")); $endtime = date("h:i:sa",$endtimestamp); if($nowtime==$endtime){ $zero = 0; $sql2 = "UPDATE RegisteredMembers SET RecoveryCode = '$zero' WHERE RecoveryCode = '$recovery_code'"; $output2 = mysql_query($sql2); if($output2==1){ $error = false; } }*/ show_change_pass_form(); } else if($count==0 || empty($recovery_code)) { echo "No such recovery code, please don't try Spamming around! "; } } ?> <?php ob_end_flush(); ?>
即使設置了“新密碼”和“確認密碼錯誤/成功”消息，但是單擊“ 更改密碼”按鈕后也看不到任何消息。 （僅密碼更改）
尚無CSS樣式。 因此，他們絕不會display:none CSS問題display:none 。
實際問題 -我希望變量$passError和$Con_passError被正確地回顯。
預先感謝您提供的幫助！
