Question

我一直在使用这个PHP代码作为我的表单验证的一部分。它在过去的6个月里一直很好用。我每次提交表单时都会突然收到以下自定义错误消息：

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

我已经在表单的字段中测试了php验证，这似乎工作正常。我没有改变我的php或ajax逻辑或html表单本身的任何内容。无法弄清楚它的错误。

这是我使用的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.';
    }
}
?>

这是JS

$(document).ready(function() {

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

        }

问题是表单不会将数据发送到指定的电子邮件。它始终显示自定义错误消息。

非常感谢任何帮助。

谢谢！

php错误报告显示以下内容：

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

更新将php_flag register_globals off添加到我的htaccess后，我不再收到php错误消息但仍未提交。继续从第72行加载自定义错误消息（php代码）。

Answer 1

邮件无法在行

中发送

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

删除＆＃39; @＆＃39;字符，它可能会给你一个消息，为什么它没有发送。

可能存在的问题可能是您不允许从服务器发送邮件或者PHP的配置发生了变化！

编辑：要捕获错误消息，您应该使用error_get_last函数。请尝试在第72行添加print_r(error_get_last()); exit;。

Answer 2

问题是由电子邮件发送引起的。检查邮件功能是否正常。问题可能出在服务器配置中。

为什么我的表单会出错？
