我有3个php文件：第一个带有表单及其验证，第二个将这些值存储在db中，第三个包含域等等。我已经尝试了将所有变量值从第一个传递到第二个php ex：$_POST，$_Get和isset()显示在Save.php。
但是值是“”或null（空），因为我在Save.php中回显它们并且没有任何内容出现。只需为我提供每个变量的消息，如下所示 - Notice: Undefined index: lname in C:\xampp\blablabla\Save.php on line 5。
连接正常，查询正常，验证正常，表单正常工作。唯一的问题是我打电话
if($valid)
{
header('Location: Save.php');
exit();
}

答案 0 :(得分：1)
这是它无法正常工作的地方：
Header('Location: Save.php');
在这里，你将控制传递给Save.php，，但你没有直接传递任何数据 ....由于它不起作用，我收集到你根本没有传递它。
您可以执行以下任一操作：
如果到目前为止已执行的文件尚未生成任何输出，那么您只需include文件Save.php：
包括＆＃34; Save.php＆＃34;
如果你想直接传递数据而且数量不大，可以把它放在GET字符串中，但要注意，它会在地址栏中以明文形式显示
标题（＆＃34;位置：Save.php？name = Vitruvio＆amp; surname = Pietrisco＆amp; age = 67＆＃34;）;
如果您想传递更多数据，可以使用会话。
在第一个文件中：
在session_start（）; //第一行
...
$ _ SESSION [＆＃39; Hello＆＃39;] =＆＃34; World＆＃34;;
在第二个文件（Save.php）中：
在session_start（）;
回声＆＃34;你说＆＃34; 。 $ _SESSION [＆＃39;你好＆＃39;];将回应你说世界＆＃39;
更新：通常，您会将验证放在执行保存的同一文件中。或者，如果要分离源，可以将所有信息包装在数组中，并将其传递给名为Save（）的函数。此函数可能是Save.php文件中的唯一函数。现在你可以做到：
$data['firstname'] = $_POST['fname'];
$data['lastname'] = $_POST['lname'];
// Now you could even put $_SESSION['data'] = $data;
// and have it all in the session!
...and also simplify the use of mysql escaping with a cycle:
foreach ($data as $field => $content) {
$data[$field] = mysql_real_escape_string($con, $content);
}
// By the way: IMPORTANT!. mysql_* functions are DEPRECATED and will be REMOVED
// (maybe soon). Use PDO instead! It takes a bit to adapt, but it's worth it.
if ($valid) {
// The file is only included if it is necessary, if data are $valid.
include "Save.php";
save($data);
}
