Question

我刚刚开始学习php，我正在建立一个＆＃34;联系我们＆＃34;将用户输入发送到我的电子邮件的表单。我已经好几天了，以为我会弄清楚，但我没有得到它。我还希望能够在我的电子邮件中接收用户的输入，并且还能够检测用户的IP地址。当我提交表单时，虽然我使用了＃34; localhost＆＃34;但我收到了所有其他输入但是IP地址。

我尝试使用<input type="hidden" name="message" value="<?php echo $_SERVER['REMOTE_ADDR']; ?>">，但我在网上看到，如果没有<input type="hidden">这样做会更好，只需处理表单处理器脚本中的所有内容。请帮助我。

<?php
$emailError = "";


$messageError = "";




function getUserIp(){

    $client = $_SERVER['HTTP_CLIENT_IP'];

    $forward = $_SERVER['HTTP_X_FORWARD_FOR'];

    $remote = $_SERVER['REMOTE_ADDR'];


    if(filter_var($client, FILTER_VALIDATE_IP)) {

         $ip = $client;

    }elseif(filter_var($forward, FILTER_VALIDATE_IP)) {

         $ip = $client;

    }else{

        $ip = $remote;

    }

 return $ip;

}





if(isset($_POST['submit'])){

    //declares variable
     $email = $_POST["email"];

    $subject = $_POST["subject"];

    $message = $_POST["message"];

  if(empty($_POST['email'])){

    $emailError = "Please enter your email";

  }

  if(empty($_POST['subject'])){

    $subjectError = "Please enter a subject?";

  }
}






if(!empty($_POST['email']) && !empty($_POST['subject'])){

    // Send the email
    $to = "you@yourdomain.com";

    $email = "From: $email";

    $subject = "Subject: $subject";

    $message = "$message" . "\n\n\n==-   Sent from the website with IP Address: " . $ip . "   -==";;

    $headers = "From: $email,";

    $send_contact=mail($to,$email,$subject,$message,$headers);

    header("Location: domain");
}


?>

更改以下部分 -

if(!empty($_POST['email']) && !empty($_POST['subject'])){

        // Send the email
        $to = "you@yourdomain.com";
        $ip =getUserIp();

        $email = "From: $email";

        $subject = "Subject: $subject";

        $message = "$message" . "\n\n\n==-   Sent from the website with IP Address: " . $ip . "   -==";;

        $headers = "From: $email,";

        $send_contact=mail($to,$email,$subject,$message,$headers);

        header("Location: domain");
    }
