我的 html 表单无法正确提交时遇到问题。我是表单的新手，一直试图让登录脚本运行，但它一直失败。我主要使用铬。这是超级愚蠢的代码，希望能证明我的问题。我猜这个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：登录帐户设置网站主要供参考
<?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>

<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>第一个按钮可以预见地重新加载页面，而其他按钮什么也不做。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代码的问题。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 !";
}
}
