【中文标题】我的网站上的 PHP 联系表单错误。 PHP 新手，但我发誓这之前有效并且停止了，我无法弄清楚如何修复它 [重复]

【英文标题】：PHP Contact form error on my website. New to PHP, but I swear this worked before and stopped and I cant figure out how to fix it [duplicate]

【问题描述】：

好的，所以我的结果是我提交了表单并且它成功完成了所有验证（比如，我输入了它捕获的名称的数字，但我的消息失败了）。我收到消息“感谢您与我们联系。我们会尽快与您联系。”这是在我的 php 页面的末尾。但是我的 Gmail 帐户没有收到电子邮件。

有一次，我仅在本地调试时遇到问题，但在我的 Azure Web 服务器上，它可以正常工作。一年后我回到我的网站，并试图记住它是如何工作的。

我很难找出任何调试选项来逐步执行代码。

表格代码：

index.html

<form name="contactform" id="contactform" method="post" action="send_form_email.php">
    <fieldset>

        <div class="form-field">
            <input name="first_name" type="text" id="first_name" placeholder="Name" value="" minlength="2" required="" aria-required="true" class="full-width">
        </div>
        <div class="form-field">
            <input name="email" type="email" id="email" placeholder="Email" value="" required="" aria-required="true" class="full-width">
        </div>
        <div class="form-field">
            <input name="subject" type="text" id="subject" placeholder="Subject" value="" class="full-width">
        </div>
        <div class="form-field">
            <textarea name="comments" id="comments" placeholder="Message" rows="10" cols="50" required="" aria-required="true" class="full-width"></textarea>
        </div>
        <div class="form-field">
            <button class="full-width btn--primary" type="submit">Submit Email</button>
            <div class="submit-loader">
                <div class="text-loader">Sending...</div>
                <div class="s-loader">
                    <div class="bounce1"></div>
                    <div class="bounce2"></div>
                    <div class="bounce3"></div>
                </div>
            </div>
        </div>

    </fieldset>
</form>

这是我的 PHP 文件：

send_form_email.php

<?php
if(isset($_POST['email'])) 
 
    // EDIT THE 2 LINES BELOW AS REQUIRED
    $email_to = "[e-mail]";
    $email_subject = "Your email subject line";
 
    function died($error) 
        // your error code can go here
        echo "We are very sorry, but there were error(s) found with the form you submitted. ";
        echo "These errors appear below.<br /><br />";
        echo $error."<br /><br />";
        echo "Please go back and fix these errors.<br /><br />";
        die();
    
 
 
    // validation expected data exists
    if(!isset($_POST['first_name']) ||
        !isset($_POST['email']) ||
        !isset($_POST['telephone']) ||
        !isset($_POST['comments'])) 
        died('We are sorry, but there appears to be a problem with the form you submitted.');       
    
 
     
 
    $first_name = $_POST['first_name']; // required
    $email_from = $_POST['email']; // required
    $telephone = $_POST['subject']; // not required
    $comments = $_POST['comments']; // required
 
    $error_message = "";
    $email_exp = '/^[A-Za-z0-9._%-]+@[A-Za-z0-9.-]+\.[A-Za-z]2,4$/';
 
  if(!preg_match($email_exp,$email_from)) 
    $error_message .= 'The Email Address you entered does not appear to be valid.<br />';
  
 
    $string_exp = "/^[A-Za-z .'-]+$/";
 
  if(!preg_match($string_exp,$first_name)) 
    $error_message .= 'The First Name you entered does not appear to be valid.<br />';
  
 
  
  if(strlen($comments) < 2) 
    $error_message .= 'The Comments you entered do not appear to be valid.<br />';
  
 
  if(strlen($error_message) > 0) 
    died($error_message);
  
 
    $email_message = "Form details below.\n\n";
 
     
    function clean_string($string) 
      $bad = array("content-type","bcc:","to:","cc:","href");
      return str_replace($bad,"",$string);
    
 
     
 
    $email_message .= "First Name: ".clean_string($first_name)."\n";
    $email_message .= "Email: ".clean_string($email_from)."\n";
    $email_message .= "Subject: ".clean_string($subject)."\n";
    $email_message .= "Comments: ".clean_string($comments)."\n";
 
// create email headers
$headers = 'From: '.$email_from."\r\n".
'Reply-To: '.$email_from."\r\n" .
'X-Mailer: PHP/' . phpversion();
@mail($email_to, $email_subject, $email_message, $headers);  
?>
 
<!-- include your own success html here -->

【问题讨论】：

呃。好吧，我不知道我以前是如何使用它的，但我担心我需要设置类似 SendGrid 的东西才能与我的 Azure Web 应用程序一起使用。

您可以尝试将其发送到您网站的电子邮件，以查明是否是 Gmail 阻止了您的电子邮件。

或者你可以只用一行PHP邮件函数来检查错误是否真的存在

【参考方案1】：

Gmail 可能会将您的电子邮件标记为垃圾邮件，或完全阻止它。尝试将Pear Mail 与 SMTP 一起使用：

require_once "Mail.php";

$from = '<[e-mail]>';
$to = '<[e-mail]>';
$subject = 'Subject';
$body = "Body";

$smtp = Mail::factory('smtp', array(
        'host' => 'ssl://smtp.gmail.com',
        'port' => '465',
        'auth' => true,
        'username' => '[e-mail]',
        'password' => 'passwordxxx'
    ));

$headers = array(
    'From' => $from,
    'To' => $to,
    'Subject' => $subject
);

$mail = $smtp->send($to, $headers, $body);

if (PEAR::isError($mail)) 
    echo('<p>' . $mail->getMessage() . '</p>');
 else 
    echo('<p>Message successfully sent!</p>');

【讨论】：

谢谢 我试过了，现在我得到一个 405 错误，这与我的 SendGrid 解决方案相同。我的网站似乎存在根本性问题，我可能会放弃。
