我有两步表格。 create.php和create2.php。两个页面都是表格。填好第一个表格后，用户按下＆＃34;继续＆＃34;并进入第二种形式，我传递并将第一种形式的值存储在隐藏的输入中。在填写并提交第二个表单后，我想要弹出窗口，这意味着成功提交表单并将所有数据插入数据库。似乎一切都运行良好，所有数据都在数据库中，但是我没有弹出窗口，我得到的是关于我的隐藏输入的未定义索引警告。
好的，这是create.php的代码：
<form class="formcss" method="post" action="create2.php" id="reportform" enctype="multipart/form-data">

<label class="tool tool1" for="name" style="margin-top:-8px;">Code of the project</br>e.g. ASD001</label>

对于第二种形式create2.php：
<?php

if(empty($_SESSION['login_user'])){
session_destroy();

}
$proc = isset($_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";

// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);

我正在使用另一个php页面将数据插入数据库。我只是没有得到可能成为问题的东西。谢谢你的帮助
答案 0 :(得分：0)
由于POST数组第一次不可用。因此，您收到此错误。如果您确实需要使用这些post变量，则应在这种情况下应用条件以避免这些错误。
我在这里添加一个，你可以做同样的事情。
试试这个：
<?php echo isset($_POST['code'])?$_POST['code']:''; ?>
