Answer 1

您创建的字段

的名称属性中缺少等号

Answer 2

将表单方法设置为GET时，您无法获得$ POST值。要么改变表单方法，要么改变php代码的一部分：

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

    $createdby = $_GET["createdby"];

Answer 3

<input type="text" id="createdby" name="createdby" class="required error"/>

因此您的输入字段不存在且$ _POST [“createdby”];为空

Answer 4

只需将表单操作更改为发布

即可

<form id="usertype" action="  " method="get" > to
<form id="usertype" action="  " method="post" > or

将$ _POST更改为$ _GET

<?php
//to display contents after posting in same page
    if (isset($_POST['submit'])) 
    {

    $createdby = $_POST["createdby"];
?>

到

<?php
    //to display contents after posting in same page
        if (isset($_GET['submit'])) 
        {

        $createdby = $_GET["createdby"];
    ?>

一个字段没有在php中提交值
