PHP问题已经解决。以下是我使用的 HTML 和 PHP 代码:
contact_form.html:
<html>
<head>
<title>My Contact Form</title>
<script src='https://www.google.com/recaptcha/api.js'></script>
</head>
<body>
<div class="contact-form">
<h3>Send me your message</h3>
<form action="app/contact.php" method="POST">
<div class="text-fields">
<span>Full Name *:</span>
<input name="full_name" type="text" class="text" value="Your Name">
</div>
<div class="text-fields">
<span>E-mail *:</span>
<input name="email" type="text" class="text" value="user@domain.com">
</div>
<div class="clearfix"> </div>
</div>
<div class="subject-field">
<span>Subject *:</span>
<input name="subject" type="text" class="text" value="Your Subject">
</div>
<div class="message-field">
<span>Message *:</span>
<textarea name="message"> </textarea>
</div>
<div class="g-recaptcha" data-sitekey="SITE-KEY-HERE"></div>
<input type="submit" value="Send" />
</form>
</div>
</body>
</html>
这是更新后的 PHP。有了这个，我也得到了我想要的发件人字段，即“发件人姓名”。
contact_form.php:
<?php
$full_name;$email;$subject;$message;$captcha;
if(isset($_POST['full_name'])){
$full_name=$_POST['full_name'];
}if(isset($_POST['email'])){
$email=$_POST['email'];
}if(isset($_POST['subject'])){
$subject=$_POST['subject'];
}if(isset($_POST['message'])){
$message=$_POST['message'];
}if(isset($_POST['g-recaptcha-response'])){
$captcha=$_POST['g-recaptcha-response'];
}
if(!$captcha){
echo 'Check the reCAPTCHA box.';
exit;
}
$response=file_get_contents("https://www.google.com/recaptcha/api/siteverify?secret=SECRET-KEY-HERE&response=".$captcha."&remoteip=".$_SERVER['REMOTE_ADDR']);
if($response.success==false)
{
echo 'You are a robot!';
}else
{
$to = "me@domain.com";
$from = $full_name . ' <'.$email.'>';
$headers = 'From: ' . $from . "\r\n";
mail ($to, $subject, $message, $headers);
echo 'Your message has been sent!';
}
?>
感谢大家的帮助。
最佳答案
试试这个!
<?php
if(isset($_POST['full_name']) && isset($_POST['full_name']) ){
$full_name = $_POST['full_name'];
$email = $_POST['email'];
$from_name_email = $full_name . '<'.$email.'>';
}
if(isset($_POST['subject'])){
$subject = $_POST['subject'];
}
if(isset($_POST['message'])){
$message = $_POST['message'];
}
}if(isset($_POST['g-recaptcha-response'])){
$captcha=$_POST['g-recaptcha-response'];
$to = "my@email.com";
$subject = "Contact Form";
$headers .= 'From: ' . $from_name_email . "\r\n";
}
if(!$captcha){
echo 'Please check the the captcha form.';
exit;
}
$response=file_get_contents("https://www.google.com/recaptcha/api/siteverify?secret=YOUR SECRET KEY GOES HERE&response=".$captcha."&remoteip=".$_SERVER['REMOTE_ADDR']);
if($response.success==false)
{
echo 'You are spammer!';
}else
{
mail ($to, $subject, $message, $headers);
echo "Your message has been sent! Thank you.";
}
?>
