PHP form to disappear after submit

本文关键字：消失提交表单 PHP | 更新日期: 2023-09-27

我正在尝试如何获取页面以确认它已被填写。

这就是我所拥有的。

<?php
if(!isset($_POST['submit']))
{echo
        '<form action="" method="post">
            <input type="text" placeholder="From" name="from"><br>
            <input type="text" placeholder="Subject" name="sub"><br>
            <input type="text" placeholder="Message"name="mess"><br>
            <input type="submit">
        </form>';}
else{
$to = 'test@test.com, '. $from=$_POST['from'];
$subject = $_POST['sub'];
$message = $_POST['mess'];
mail ( $to , $subject , $message);
    echo 'thanks for submitting!<br>';}
?>

替换以下代码：

mail ( $to , $subject , $message);
    echo 'thanks for submitting!<br>';

通过这个：

if(@mail($to, $subject, $message)) {
  echo "thanks for submitting";
}else{
  echo "Unable to submit your email.";
}
