PHP $ _POST没有传递字段元素

Question

我正在处理客户端的联系表单，但由于某种原因，它没有传递正确的变量。看看一些代码，看看你是否能找到任何东西......我没有想法。

contact.php

<form name="contact" method="post" action="thankyou.php"> 
    <input type="hidden" name="flag" value="1" /> 
    <table style="width: 500px;"> 
    <tr> 
    <td><p><em><strong>Your email: *</strong></em></p></td> 
    <td><input name="email" type="text" size="30" /></td> 
    </tr> 
    <tr> 
    <td><p><em><strong>Subject:</strong></em></p></td> 
    <td><input name="subject" type="text" size="30" /></td> 
    </tr> 
    <tr> 
    <td><p><em><strong>Message: *</strong></em></p></td> 
    <td><textarea name="message" type="text" rows="7" cols="30"></textarea></td> 
    </tr> 
    <tr> 
    <td></td> 
    <td><div style="height:5px"></div></td> 
    </tr> 
    <tr> 
    <td colspan="2"><p>To help protect us against spam, please type <em>storage</em> below: *</p></td> 
    </tr> 
    <tr> 
    <td></td> 
    <td><input name="spam_test" maxlength="7" type="text" size="5" /></td> 
    </tr> 
    <tr> 
    <td></td> 
    <td><div style="height:5px"></div></td> 
    </tr> 
    <tr> 
    <td></td> 
    <td><input type="submit" value="Send" /> 
    <input type="reset" value="Reset" /></td> 
    </tr> 
    </table> 
</form> 

thankyou.php

<?php 
    $user_message = ""; 
    if(isset($_POST['flag'])) { 
    $flag = "true"; 
    if (strlen($_POST['message']) > 20000) { 
     $user_message = "Message too long, please shorten."; 
     $flag = "false"; 
    } 
    if (strlen($_POST['message']) < 1) { 
     $user_message = "Message cannot be blank."; 
     $flag = "false"; 
    } 
    if (strlen($_POST['subject']) > 5000) { 
     $user_message = "Subject too long, please shorten."; 
     $flag = "false"; 
    } 
    if(!check_email($_POST['email'])) { 
     $user_message = "Invalid email address, please re-enter."; 
     $flag = "false"; 
    } 
    if($_POST['spam_test'] != "storage") { 
     $user_message = "Please fill out the spam prevention field correctly."; 
     $flag = "false"; 
    } 
    if($flag == "true") { 
     $user_message = "Your message has been sent. We will be in touch shortly."; 

     $headers = "From: ContactForm@example.com\r\n"; 
     $headers .= "Reply-To: " . $_POST['email'] . "\r\n"; 
     $headers .= "Return-Path: " . $_POST['email'] . "\r\n"; 

     $msg = "This is an automatically generated email from the Contact Form on mrstore.co.uk - below is a message from a user:\n\n"; 
     $msg .= "User's email: " . $_POST['email'] . "\n\n"; 
     $msg .= "Message: " . $_POST['message'] . "\n"; 

     $subject = "Contact Us Message From Website: " . $_POST['subject']; 

     if(!mail('user@example.org', $subject, $msg, $headers)) { 
     $user_message = "Error Sending Email, please try again later."; 
     } 
    } 
    } 
?> 
<h2><?php echo $user_message; ?></h2> 

EDIT 以下是的print_r的结果（$ _ POST）...领域元素被携带到三江源.php，但没有正确处理（例如，垃圾邮件密钥在示例中是错误的），并且邮件未被发送。

Array ([flag] => true [email] => user@example.org [subject] => This is the subject [message] => hello moto [spam_test] => blah) 

EDIT 2 我觉得我越来越接近计算出来，但现在它的投掷500服务器错误。我还创建了变量$电子邮件中thankyou.php并指出，$ _ POST [“邮件”]）这里的功能，check_email ...

function check_email($email) { 
     // First, we check that there's one @ symbol, and that the lengths are right 
     if (!ereg("^[^@]{1,64}@[^@]{1,255}$", $email)) { 
      // Email invalid because wrong number of characters in one section, or wrong number of @ symbols. 
      return false; 
     } 
     // Split it into sections to make life easier 
     $email_array = explode("@", $email); 
     $local_array = explode(".", $email_array[0]); 
     for ($i = 0; $i < sizeof($local_array); $i++) { 
      if (!ereg("^(([A-Za-z0-9!#$%&'*+/=?^_`{|}~-][A-Za-z0-9!#$%&'*+/=?^_`{|}~\.-]{0,63})|(\"[^(\\|\")]{0,62}\"))$", $local_array[$i])) { 
       return false; 
      } 
     } 
     if (!ereg("^\[?[0-9\.]+\]?$", $email_array[1])) { // Check if domain is IP. If not, it should be valid domain name 
      $domain_array = explode(".", $email_array[1]); 
      if (sizeof($domain_array) < 2) { 
       return false; // Not enough parts to domain 
      } 
      for ($i = 0; $i < sizeof($domain_array); $i++) { 
       if (!ereg("^(([A-Za-z0-9][A-Za-z0-9-]{0,61}[A-Za-z0-9])|([A-Za-z0-9]+))$", $domain_array[$i])) { 
        return false; 
       } 
      } 
     } 
     return true; 
    } 

最后编辑...我希望！ if语句我已经收窄，这...

if($flag == "true") { 
          $headers = "From: ContactForm@mrstore.co.uk\r\n"; 
          $headers .= "Reply-To: " . $_POST['email'] . "\r\n"; 
          $headers .= "Return-Path: " . $_POST['email'] . "\r\n"; 

          $msg = "This is an automatically generated email from the Contact Form on mrstore.co.uk - below is a message from a user:\n\n"; 
          $msg .= "User's email: " . $_POST['email'] . "\n\n"; 
          $msg .= "Message: " . $_POST['message'] . "\n"; 

          $subject = "Contact Us Message From Website: " . $_POST['subject']; 
          mail("dgengler@ccseo.com", $subject, $msg, $headers); 
          $user_message = "Your message has been sent. We will be in touch shortly.";    } 

Answer 1

我找不到任何问题发送POST数据。

确保您的'check_email'功能存在。和您的电子邮件发送功能正常工作。

Answer 2

当尝试使用此代码来重新创建，我唯一的问题是这一行：

if(!check_email($_POST['email'])) { 

也许尝试：

if(!filter_var($_POST['email'], FILTER_VALIDATE_EMAIL)) { 

，看看它是否工作。
