爲什麼我的表單會拋出錯誤？

Question

我一直在使用這個php代碼作爲我的表單驗證的一部分。它在過去6個月裏一直工作正常。突然我提交表單每次我不斷收到以下自定義錯誤消息我已經安裝在這裏：

header('HTTP/1.1 500 Our server is under maintenance!<br> If this error persists please contact us directly: <strong>something@test.com</strong>'); 

我測試過的表單字段中的PHP驗證這似乎工作確定。 我沒有改變任何東西在我的PHP或AJAX邏輯或HTML格式本身。無法弄清楚它有什麼問題。

這裏是我使用PHP：

<?php 
if($_POST) 
{ 
    //check if its an ajax request, exit if not 
    if(!isset($_SERVER['HTTP_X_REQUESTED_WITH']) AND strtolower($_SERVER['HTTP_X_REQUESTED_WITH']) != 'xmlhttprequest') { 
     die(); 
    } 


    //check $_POST vars are set, exit if any missing 
    if(!isset($_POST["userName"]) || !isset($_POST["userLastName"]) || !isset($_POST["userEmail"]) || !isset($_POST["userArrival"]) || !isset($_POST["userNumberPeople"]) 
    || !isset($_POST["userPickupLocation"]) || !isset($_POST["userRequest"]) || !isset($_POST["userTourSelection"])) 
    { 
     die(); 
    } 

    //Sanitize input data using PHP filter_var(). 
    $user_Name    = filter_var($_POST["userName"], FILTER_SANITIZE_STRING); 
    $user_LastName   = filter_var($_POST["userLastName"], FILTER_SANITIZE_STRING); 
    $user_Email    = filter_var($_POST["userEmail"], FILTER_SANITIZE_EMAIL); 
    $user_TourSelection  = filter_var($_POST["userTourSelection"], FILTER_SANITIZE_STRING); 
    $user_Arrival   = filter_var($_POST["userArrival"], FILTER_SANITIZE_STRING); 
    $user_NumberPeople  = filter_var($_POST["userNumberPeople"], FILTER_SANITIZE_STRING); 
    $user_PickupLocation = filter_var($_POST["userPickupLocation"], FILTER_SANITIZE_STRING); 
    $user_Request   = filter_var($_POST["userRequest"], FILTER_SANITIZE_STRING); 



    $to_Email  = "something@test.com"; //Replace with recipient email address 
    $subject  = 'Tour request: '.$user_TourSelection.' '; //Subject line for emails 


    //additional php validation 
    if(strlen($user_Name)<2) // If length is less than 4 it will throw an HTTP error. 
    { 
     header('HTTP/1.1 500 Name is too short or empty!'); 
     exit(); 
    } 
    if(!filter_var($user_Email, FILTER_VALIDATE_EMAIL)) //email validation 
    { 
     header('HTTP/1.1 500 Please enter a valid email address!'); 
     exit(); 
    } 
    if(strlen($user_Request)<5) //check emtpy message 
    { 
     header('HTTP/1.1 500 Please explain in a few words how you would like us to assist you.'); 
     exit(); 
    } 


    // message 
$message = '<strong>Name:</strong> '.$user_Name.' '.$user_LastName.' <br><br> 
      <strong>Date of Arrival:</strong> '.$user_Arrival.' <br><br> 
      <strong>Tour:</strong> '.$user_TourSelection.' <br><br> 
      <strong>Number of people:</strong> '.$user_NumberPeople.' <br><br> 
      <strong>Pick-Up Location:</strong> '.$user_PickupLocation.' <br><br> 
      <strong>Request:</strong> '.$user_Request.' 
      '; 


//proceed with PHP email. 
    $headers = 'From: '.$user_Email.'' . "\r\n" . 
    $headers .='Reply-To: '.$user_Email.'' . "\r\n" ; 
    $headers .= 'MIME-Version: 1.0' . "\r\n"; 
    $headers .= 'Content-type: text/html; charset=iso-8859-1' . "\r\n"; 
    $headers .='X-Mailer: PHP/' . phpversion(); 

    @$sentMail = mail($to_Email, $subject, $message, $headers); 

    if(!$sentMail) 
    { 
     header('HTTP/1.1 500 Our server is under maintenance!<br> If this error persists please contact us directly: <strong>something@test.com</strong>'); 
     exit(); 
    }else{ 
     echo 'Congratulations '.$user_Name .'! '; 
     echo 'We have received your request and we will respond as soon as possible.'; 
    } 
} 
?> 

這裏是JS

$(document).ready(function() { 

    $("#submit_btn").click(function() { 
     //collect input field values 
     var user_name  = $('input[name=firstName]').val(); 
     var user_lastname = $('input[name=lastName]').val();

     var user_arrivaldate = $('input[name=arrivalDate]').val(); 
     var user_request = $('textarea[name=request]').val(); 
     var user_tourselection = $('#tourSelection option:selected').val(); 

     //simple validation at client's end 
     //we simply change border color to red if empty field using .css() 
     var proceed = true; 

     if(user_name==""){ 
      $('input[name=firstName]').addClass("required"); 
      proceed = false; 
     } 
     if(user_lastname==""){ 
      $('input[name=lastName]').addClass("required"); 
      proceed = false; 
     } 
     if(user_email=="") {

      proceed = false; 
     } 
     if(user_numberpeople=="") {  
      $('select#numberofPeople').addClass("required"); 
      proceed = false; 
     } 

     if(user_pickuplocation=="") {

      proceed = false; 
     } 


     if(user_arrivaldate=="") {  
      $('input[name=arrivalDate]').addClass("required"); 
      proceed = false; 
     } 

     if(user_request=="") { 
      $('textarea[name=request]').addClass("required"); 
      proceed = false; 
     } 

     if(user_tourselection=="") { 
      $('select#tourSelection').addClass("required"); 
      proceed = false; 
     } 



     //everything looks good! proceed... 
     if(proceed){ 

      //deactivate button 
      $("#reservation-form button#submit_btn").attr("disabled", "disabled").text('Processing...').addClass("processing-state"); 

      //data to be sent to server 
      var post_data = {

      }; 

      //Ajax post data to server 
      $.post('http://www.myurl.com/reservation.php', post_data, function(data){ 

       //load success message in #result div element, with slide effect. 
       $("#result").hide().html('<span class="success">'+data+'</span>').slideDown(); 

       $('label').hide(); 
       $('select').hide(); 
       $('#reservation-form h2').hide(); 
       ga('send', 'event', 'tours', 'request-tour', 'Tour-Request-Complete'); 


      }).fail(function(err) { //load any error data 

       $("#reservation-form button#submit_btn").text('REQUEST FAILED...').removeClass("processing-state").addClass("fail-state"); 
       $("#result").hide().html('<div class="error">'+err.statusText+'</div>').slideDown(); 

       ga('send', 'event', 'tours', 'request-tour', 'Tour-Request-Error'); 

       $("#reservation-form input, #reservation-form textarea").focus(function() {

        $("#result").slideUp(); 

       }); 

      }); 
     } 
    }); 


    //reset previously set border colors and hide all message on .keyup() 
    $("input, textarea").keyup(function() { 
     $(this).removeClass("required"); 
    }); 


    $("select#tourSelection").change(function() { 

     if($("select#tourSelection").val() != '')

的問題是，形式不發送數據到指定的電子郵件。它總是顯示自定義錯誤消息。

任何幫助，非常感謝。

謝謝！

PHP錯誤報告顯示以下內容：

Array ([type] => 8192 [message] => Directive 'register_globals' is deprecated in PHP 5.3 and greater [file] => Unknown [line] => 0) 

更新 加入php_flag register_globals off我htaccess的我不再讓PHP的錯誤消息，但它仍然沒有提交後。保持從第72行（php代碼）加載自定義錯誤消息。

Answer 1

該問題是由電子郵件發送引起的。 檢查郵件功能是否正常。問題可能出現在服務器配置中。

Answer 2

郵件無法在該行

@$sentMail = mail($to_Email, $subject, $message, $headers); 

刪除「@」字符發送，它可能會給你爲什麼沒有發送的消息。

可能的問題可能是您不允許從服務器發送郵件或PHP配置中的某些內容已更改！

編輯：要捕獲錯誤消息，您應該使用error_get_last函數。嘗試在第72行添加print_r(error_get_last()); exit;.
