HTML 按钮提交未激活 php 代码

Question

我的 html 表单提交不正确时遇到问题。我是表单的新手，一直在尝试让登录脚本运行，但一直失败。我主要使用 chrome。这是超级简化的代码，希望能说明我的问题。我猜这段代码有什么问题是在扩展代码中。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">
</head>
<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>
</html>

第一个按钮可以预料地重新加载页面，而其他按钮什么都不做。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。下面的代码主要用于提供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 !";
    }
}
?>

Answer 1

由于php://input显示了表单值（根据我在评论中对您进行的测试运行），我们知道PHP正在正确接收数据。

默认情况下，PHP会根据需要将请求参数放在$_GET和$_POST中。在您的情况下，这似乎没有发生。我建议您查看 php.ini 文件并添加以下设置：

variables_order = "GPCS"

可能已经有 variables_order 行，所以在这种情况下只需对其进行编辑 (documentation)。

Answer 2

所以经过一番搜索我忘记透露我使用的是PHPstorm。我没有想到的原因是我一直在使用的另一台计算机上没有安装 PHPstorm，但是由于我在两台计算机上都使用 Intellij，所以 PHPstorm 中的这个错误转移了，因为 Intellij 将使用 PHPstorm 插件。似乎 10.1-10.3 这个错误仍然存在 POST 仍然是空的。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，或者至少工作得更好。两种解决方案要么等待 PHPstorm 修复此错误，要么更好地转移到 Apache。
