考虑到我使用PHP的经验有限，我使用的联系表单生成器几乎可以按照我的意愿运行。表单及其所有变量都能正常运行，但是在收到电子邮件后，它会将我自己的域添加为发件人电子邮件。我希望将填写联系表单的电子邮件的人作为发件人，这样我就可以轻松回复邮件（而不是复制并粘贴邮件中的电子邮件地址）。
以下是代码的一部分：
<?php
$where_form_is="http://".$_SERVER['SERVER_NAME'].strrev(strstr(strrev($_SERVER['PHP_SELF']),"/"));
session_start();
if( ($_SESSION['security_code']==$_POST['security_code']) && (!empty($_POST['security_code'])) ) {
// Checkbox handling
$field_4_opts = $_POST['field_4'][0].",". $_POST['field_4'][1].",". $_POST['field_4'][2];
// Checkbox handling
$field_5_opts = $_POST['field_5'][0].",". $_POST['field_5'][1].",". $_POST['field_5'][2].",". $_POST['field_5'][3];
mail("mail@mail.com","phpFormGenerator - Form submission","Form data:

你能找到我需要改变的东西吗？

在PHP中调用mail函数之前添加相关标题。
$headers = 'From: user@example.com' . "\r\n" .
'Reply-To: user@example.com' . "\r\n";
mail($to, $subject, $message, $headers);
在您的情况下：
<?php
$where_form_is="http://".$_SERVER['SERVER_NAME'].strrev(strstr(strrev($_SERVER['PHP_SELF']),"/"));
session_start();
if( ($_SESSION['security_code']==$_POST['security_code']) && (!empty($_POST['security_code'])) ) {
// Checkbox handling
$field_4_opts = $_POST['field_4'][0].",". $_POST['field_4'][1].",". $_POST['field_4'][2];
// Checkbox handling
$field_5_opts = $_POST['field_5'][0].",". $_POST['field_5'][1].",". $_POST['field_5'][2].",". $_POST['field_5'][3];
$message = "Form data:
Your Name:: " . $_POST['field_1'] . "
Country:: " . $_POST['field_2'] . "
Your Email:: " . $_POST['field_3'] . "
Your areas of interest:: $field_4_opts
What type of articles are you interested in writing?:: $field_5_opts
Any other types of articles that interest you?:: " . $_POST['field_6'] . "
Approximately how often will you contribute?: " . $_POST['field_7'] . "
Your blog/website:: " . $_POST['field_8'] . "
What would make you a good contributor?: " . $_POST['field_9'] . "

";
$headers = 'From: '.$_POST['field_3']. "\r\n" .
'Reply-To: '.$_POST['field_3'] . "\r\n" .
'X-Mailer: PHP/' . phpversion();
mail("mail@mail.com","phpFormGenerator - Form submission", $message, $headers);
include("confirm.html");
}
else {
echo "Invalid Captcha String.";
}
?>

你应该去学习PHP，自动生成的表单代码很糟糕。
<?php
$where_form_is="http://".$_SERVER['SERVER_NAME'].strrev(strstr(strrev($_SERVER['PHP_SELF']),"/"));
session_start();
if( ($_SESSION['security_code']==$_POST['security_code']) && (!empty($_POST['security_code'])) ) {
// Checkbox handling
$field_4_opts = $_POST['field_4'][0].",". $_POST['field_4'][1].",". $_POST['field_4'][2];
// Checkbox handling
$field_5_opts = $_POST['field_5'][0].",". $_POST['field_5'][1].",". $_POST['field_5'][2].",". $_POST['field_5'][3];
mail("mail@mail.com","phpFormGenerator - Form submission","Form data:
Your Name:: " . $_POST['field_1'] . "
Country:: " . $_POST['field_2'] . "
Your Email:: " . $_POST['field_3'] . "
Your areas of interest:: $field_4_opts
What type of articles are you interested in writing?:: $field_5_opts
Any other types of articles that interest you?:: " . $_POST['field_6'] . "
Approximately how often will you contribute?: " . $_POST['field_7'] . "
Your blog/website:: " . $_POST['field_8'] . "

", 'From: ' . $_POST['field_3']);
include("confirm.html");
}
else {
echo "Invalid Captcha String.";
}
?>
我在mail（）函数中添加了一个新参数，用于设置from标头。 , 'From: ' . $_POST['field_3']是我添加的内容。看来field_3应该包含用户的电子邮件。试一试，看看它是否有效。

只需让你的代码看起来很漂亮，并为它做一些标题..它会完成你的工作 使用标题，你可以做任何你可以用你的电子邮件客户端做的事情，如GMAIL ..（附加文件或其他任何东西）
<pre>
$headers = 'From: abc@example.com' . "\r\n" .
'Reply-To: def@example.com' . "\r\n" .
'X-Mailer: PHP/' . phpversion();
$message = "Form data:
Your Name:: " . $_POST['field_1'] . "
Country:: " . $_POST['field_2'] . "
Your Email:: " . $_POST['field_3'] . "
Your areas of interest:: $field_4_opts
What type of articles are you interested in writing?:: $field_5_opts
Any other types of articles that interest you?:: " . $_POST['field_6'] . "
Approximately how often will you contribute?: " . $_POST['field_7'] . "
Your blog/website:: " . $_POST['field_8'] . "
What would make you a good contributor?: " . $_POST['field_9'] . "

";
$subject = "phpFormGenerator - Form submission"
$to = "mail@mail.com"
mail($to ,$subject,$message, $headers);
