后apeeared未定义索引我有两个步骤的形式。 create.php和create2.php。两页都是表格。在第一个表单填充后，用户按下“继续”，然后进入第二个表单，在该表单中，我将第一个表单的值存储在隐藏的输入中。填写并提交第二个表单后，我想弹出窗口，这意味着成功提交表单并将所有数据插入数据库。看来，一切工作正常，所有数据都在数据库中，但我没有弹出窗口，我得到的是未定义的索引警告关于我的隐藏输入。提交表单
确定这里是create.php代码：
<form class="formcss" method="post" action="create2.php" id="reportform" enctype="multipart/form-data">

而对于第二种形式create2.php：
<?php
session_start();
//if user haven't sign in will redirect user to login page
if(empty($_SESSION['login_user'])){
session_destroy();
header("Location: login.php");
}
$proc = isset($_POST['process'])?$_POST['process']:'';
//$proc=$_POST['process'];
$len = count($proc); // getting length of ur array that u need to condition ur loop
$num = isset($_POST['numberpl'])?$_POST['numberpl']:'';
//$num=$_POST['numberpl'];
//$len2 = count($num); // getting length of ur array that u need to condition ur loop
include 'verification/verify_form_details2.php';
require_once('inc/config.php');
//include 'verification/verify_form_details.php';
ob_start();
$servername = "localhost";
$username = "root";
$password = "";
$dbname = "pp";
// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);
// Check connection
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}
?>

这是我第二次提交表格后得到：

我用另一个PHP页面将数据插入到数据库中。我只是不明白什么是问题。感谢您的帮助
这段代码写在Create.php或create2.php？请分享这两个文件的代码。 –
@AJ见编辑后 –
感谢您的编辑。但是你没有提供完整的create2.php代码。不过，我想说你必须在回应一些事情之前先使用一个条件。我发布了一个答案，看看它是否有帮助。 –
