Question

我正在尝试创建联系表单。我想在h1下方显示$ result，但我收到以下通知：

注意：未定义的索引：在第4行的C：\ xampp \ htdocs \ contact-form \ contact.php中提交

注意：未定义的变量：在第48行产生C：\ xampp \ htdocs \ contact-form \ contact.php

以下是截图：https://www.dropbox.com/s/ltoc8j3j6iyppc5/Screenshot%202016-03-14%2014.14.19.png?dl=0

第4行是：

    if ($_POST["submit"]) {

任何人都可以提供通知的线索吗？

<?php
$result="test";

    if ($_POST["submit"]) {

        $result="Form submitted";

    }

?>
