javascript - 表单提交打开php页面

Question

我在 html 页面上有一个表单。它的操作为 mailer.php。所有代码都工作正常，但提交后，页面转到 mailer.php，浏览器在屏幕上显示一个空白页面

contactus.html 表单标签:

<form id="form_20" action="mailer.php" method="post" target="_self" 
      enctype="multipart/form-data">
    //input fields here
</form>

mailer.php 文件:

<?php
$to = '---------------'; //Removed for privacy
$subject = 'New Enquiry';

$name = $_POST['Name'];
$tel = $_POST['Number'];
$email = $_POST['Email'];
$comments = $_POST['Message'];

$body = "From: $name \nNumber: $tel \nEmail id: $email \nComments: $comments";
$headers = 'FROM: ---------------------------'.PHP_EOL; //Removed for privacy
mail($to, $subject, $body, $headers);
echo '<script>alert("Your data has been submitted.");</script>';
?>

代码工作正常，我也收到了邮件。我遇到的唯一问题是页面重定向到 mailer.php

Answer 1

将用户返回到上一页:

header('Location: http://www.example.com/foo.php?back=yes'); //add your url

邮件调用后，删除脚本

在 foo.php

if ($_GET['back']=='yes'){
echo '<script>alert("Your data has been submitted.");</script>';
}
