我遇到了我的html表單沒有正確提交的問題。我是新來的形式，並一直試圖讓登錄腳本去，但它一直在失敗。我大多使用鉻。這是超級愚蠢的代碼，希望能夠證明我的問題。我猜測這段代碼在擴展代碼中出了什麼問題。這是我用我的登錄編碼的網站：login account setup site mainly for referenceHTML按鈕提交不激活php代碼
<?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>的第一個按鈕可預見的重新加載頁面，而其他的什麼也不做。這是我需要工作的擴展主代碼。再次，我猜測上面的代碼可能解釋了下面的代碼有什麼問題。下面的代碼主要是爲了給出上下文和更準確的答案。
<?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 !";
}
}

讓我們來測試：在腳本的頂部，你做'的var_dump（$ _ POST）'和'回聲的file_get_contents（ 'PHP：//輸入'）'，在每行顯示的內容？ – BeetleJuice
我得到：array（0）{} submit =提交 –
它似乎是通過按鈕值，但我希望它通過按鈕名稱，我雖然它。我引用的網站和擴展的代碼沒有使用按鈕中的值字段，我覺得我想保持這種方式，除非絕對需要。看來，如果聲明 –
