我試圖在數據庫中插入簡單的用戶名。 我在bootstrap中編寫了代碼，然後將其複製到netbeans中，然後在其中插入php代碼。 腳本運行良好，但是當我試圖提交在數據庫中插入名稱時，提交按鈕被禁用，不會給出任何錯誤或重定向到另一個頁面。 請幫忙。 我是bootstrap新手。點擊時突然禁用了提交按鈕
<?php
include 'includes/db_connection.php';
if (isset($_POST['submit']))
{
//$name = filter_input(INPUT_POST, 'name',FILTER_SANITIZE_STRING);
//$firstname=filter_string('firstname');
$firstname = $_POST['firstname'];
$sql1 ="INSERT INTO student (firstname)
VALUES ('$firstname')";
$res1 = mysqli_query($conn, $sql1);
if($res1)
{
//$last_id = mysqli_insert_id($conn);
header("Location: successful_message.php");
//echo 'Successful';
// . " Last inserted ID is: " . $last_id;
}
else

header("Location: valid_test.php");
