为什么使用此HTML电子邮件表单无法处理此PHP代码？

我正在尝试通过表单发送电子邮件，但它不起作用，每次我尝试发送时，它都要求下载

php

文件

HTML电子邮件代码表单如下：

<form method="post" name="contact_form" action="contact-form-handler.php">
    <div class="form-group">
        <input type="text" class="form-control" placeholder="Name" name="name">
    </div>
    <div class="form-group">
        <input type="text" class="form-control" placeholder="Email" name="email">
    </div>
    <div class="form-group">
        <input type="text" class="form-control" placeholder="Subject" name="subject">
    </div>
    <div class="form-group">
        <textarea name="message" id="message" cols="30" rows="7" class="form-control" placeholder="Message"></textarea>
    </div>
    <div class="form-group">
        <input type="submit" class="btn btn-primary btn-send-message" value="Send Message">
    </div>

<?php
$errors = '';
$myemail = 'angelribeiro.10@gmail.com';
if(empty($_POST['name'])  ||
    empty($_POST['subject']) ||
    empty($_POST['email']) ||
    empty($_POST['message']))
{
    $errors .= "\n Error: all fields are required";
}
$name = $_POST['name'];
$email_address = $_POST['email'];
$email_subject = $_POST['subject'];
$message = $_POST['message'];
if (!preg_match(
"/^[_a-z0-9-]+(\.[_a-z0-9-]+)*@[a-z0-9-]+(\.[a-z0-9-]+)*(\.[a-z]{2,3})$/i",
$email_address))
{
    $errors .= "\n Error: Invalid email address";
}

if( empty($errors))
{
$to = $myemail;
$email_subject = "Contact form submission: $name";
$email_body = "You have received a new message. ".
" Here are the details:\n Name: $name \n ".
"Email: $email_address\n Message \n $message";
$headers = "From: $myemail\n";
$headers .= "Reply-To: $email_address";
mail($to,$email_subject,$email_body,$headers);
//redirect to the 'thank you' page
header('Location: contact-form-thank-you.html');
}
?>

结果如下：

PHP代码如下所示：

<form method="post" name="contact_form" action="contact-form-handler.php">
    <div class="form-group">
        <input type="text" class="form-control" placeholder="Name" name="name">
    </div>
    <div class="form-group">
        <input type="text" class="form-control" placeholder="Email" name="email">
    </div>
    <div class="form-group">
        <input type="text" class="form-control" placeholder="Subject" name="subject">
    </div>
    <div class="form-group">
        <textarea name="message" id="message" cols="30" rows="7" class="form-control" placeholder="Message"></textarea>
    </div>
    <div class="form-group">
        <input type="submit" class="btn btn-primary btn-send-message" value="Send Message">
    </div>

<?php
$errors = '';
$myemail = 'angelribeiro.10@gmail.com';
if(empty($_POST['name'])  ||
    empty($_POST['subject']) ||
    empty($_POST['email']) ||
    empty($_POST['message']))
{
    $errors .= "\n Error: all fields are required";
}
$name = $_POST['name'];
$email_address = $_POST['email'];
$email_subject = $_POST['subject'];
$message = $_POST['message'];
if (!preg_match(
"/^[_a-z0-9-]+(\.[_a-z0-9-]+)*@[a-z0-9-]+(\.[a-z0-9-]+)*(\.[a-z]{2,3})$/i",
$email_address))
{
    $errors .= "\n Error: Invalid email address";
}

if( empty($errors))
{
$to = $myemail;
$email_subject = "Contact form submission: $name";
$email_body = "You have received a new message. ".
" Here are the details:\n Name: $name \n ".
"Email: $email_address\n Message \n $message";
$headers = "From: $myemail\n";
$headers .= "Reply-To: $email_address";
mail($to,$email_subject,$email_body,$headers);
//redirect to the 'thank you' page
header('Location: contact-form-thank-you.html');
}
?>

非常感谢。

pos复制：您的HTML似乎不完整。你有结束标记吗？这是否回答了你的问题？“每次我尝试发送它时，都会要求下载php文件。”-我现在明白了。查阅副本。最重要的是第一个。
