我的html表单无法正确提交存在问题。我是表格的新手，并且一直试图让登录脚本继续运行，但它已经失败了。我主要使用铬。这是超级愚蠢的代码，希望能够证明我的问题。我猜这个代码在扩展代码中有什么问题。这是我用于登录编码的网站：login account setup site mainly for reference
<?php
//this is here for testing
session_start();
//this shows
echo "something";
//none of these show
if(isset($_POST['submit'])){
echo "something";
echo "something";
echo "something";
echo "something";
}
if(isset($_POST['submit2'])){
echo "something";
echo "something";
echo "something";
echo "something";
}if(isset($_POST['submit3'])){
echo "something";
echo "something";
echo "something";
echo "something";
}
?>
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">

<body>
<footer>
<!-- I have tried it with and without an action -->
<form action="button_test.php" method="post" id="this" style="width: 100%; height: 100%; background-color: darkblue;">
<button type="submit" name="submit" id="submit" class="button" value="Submit">this is something</button>
<button type="button" name="submit2" id="submit2" class="button" value="this">this is something2</button>
<input type="button" name="submit3" id="submit3" class="button" value="true"/>
</form>
</footer>
</body>

第一个按钮可预测地重新加载页面，而其他按钮则不执行任何操作。这是我需要工作的扩展主代码。再一次，我猜测上面的代码可能解释了下面的代码有什么问题。下面的代码主要是为了给出上下文和更准确的答案。
<?php
//require once the DatabaseController.php file,
require_once 'Controllers/DatabaseController.php';
echo "this happend1";
// Creates a data connect object that creates a connection to
// a database
$connection = new DataConnect;
//Run the user_load function to set the user
$connection->user_load();
echo "this happend2";
/*
* Runs the in_loggedin function from a
* user object and checks if it is blank
*/
if($user->is_loggedin()!="")
{
echo "this happend3";
//return user to logged in home page if
//they are logged in
$user->redirect('index.php');
}
echo "this happend4";
/*
* THIS DOES NOT WORK FOR SOME REASON
*/
if(isset($_POST['btn-login']))
{
echo "this happend5";
//Load the variables with the new form data that has been executed
$uname = $_POST['txt_uname_email'];
$umail = $_POST['txt_uname_email'];
$upass = $_POST['txt_password'];
//If the user->login call is successful, go to home fully logged in
if($user->login($uname,$umail,$upass))
{
//Go to home, fully logged in
$user->redirect('index.php');
}
else
{
//Error
$error = "Wrong Details !";
}
}
?>

由于php://input显示了表单值（根据我在评论中运行的测试），我们知道PHP正在接收数据。
默认情况下，PHP会根据需要在$_GET和$_POST中放置请求参数。在你的情况下，这似乎并没有发生。我建议您查看php.ini文件并添加以下设置：
variables_order = "GPCS"
可能已经存在variables_order行，因此只需在此情况下进行修改（documentation）。

所以经过一些搜索后我忘了透露我使用的是PHPstorm。我没有想到这个问题的原因是PHPstorm没有安装在我一直使用的另一台计算机上，但是因为我在两台计算机上都使用Intellij，所以PHPstorm中的这个错误都被转移，因为Intellij将使用PHPstorm插件。似乎10.1-10.3这个bug在POST保持为空的情况下仍然存在。我不确定它是否已修复，所以我转移到Apache并让它做网络服务。一切正常，或者至少效果更好。这2个解决方案要么等待PHPstorm来修复这个bug，要么更好地转移到Apache。
