在php表单提交时创建成功消息

Question

我试图使php邮件表单在成功提交时显示成功消息。我是php的新手，我不知道如何使其工作。就像它现在的样子，提交后，站点只是在页面顶部重新加载。我希望它刷新在联系人div并显示一个成功消息。

联系div HTML：

<div class="contact-wrapper" >
  <div class="contact">
    <div class="contact-left" id="contact">
        <?php
        if (isset($_REQUEST['email'])) {
            echo "Thank you for your message.";
        }
        $mail_form = include('php/mail_form.php'); ?>
    </div> <!-- end div contact -->

PHP的联系人：

<?php
function spamcheck($field)
  {
  //filter_var() sanitizes the e-mail
  //address using FILTER_SANITIZE_EMAIL
  $field=filter_var($field, FILTER_SANITIZE_EMAIL);

  //filter_var() validates the e-mail
  //address using FILTER_VALIDATE_EMAIL
  if(filter_var($field, FILTER_VALIDATE_EMAIL))
    {
    return TRUE;
    }
  else
    {
    return FALSE;
    }
  }

if (isset($_REQUEST['email']))
  {//if "email" is filled out, proceed

  //check if the email address is invalid
  $mailcheck = spamcheck($_REQUEST['email']);
  if ($mailcheck==FALSE)
    {
    echo "Invalid input";
    }
  else
    {//send email
    $email = $_REQUEST['email'] ;
    $subject = $_REQUEST['subject'] ;
    $message = $_REQUEST['message'] ;
    mail("[e-mail]", "Subject: $subject",
    $message, "From: $email" );
    header("location: index.php");
    }
  }
?>

请尝试此代码...您需要暂停脚本一段时间，以便用户可以看到成功或失败消息。没有睡眠，用户将无法看到消息，因为头将立即执行。

if(mail("[e-mail]", "Subject: $subject",$message, "From: $email" )){
   echo "Thank you for your message";
   sleep(2); // sleep for 2 seconds. Enough to display success message
   //header will execute after 2000ms(2s)
   header("location: index.php");
}else{
   echo "Unable to send message";
   sleep(2); // sleep for 2 seconds 
   header("location: index.php");
}

或尝试下面给出的代码：

从PHP联系

if(mail("[e-mail]", "Subject: $subject",$message, "From: $email" )){
   header("location: index.php?status=1");
}else{ 
   header("location: index.php?status=0");
}

在index.php中

 if(isset($_GET['status'])){
     $status = $_GET['status'];
     if($status == 1){
        echo "Thank you for your message";
     }else if($status == 0){
        echo "Unable to send message";
     }
 }
