我想在数据库中插入简单的用户名。 我在bootstrap中编写了代码，然后将其复制到netbeans，然后在其中插入php代码。 脚本运行良好，但是当我尝试提交以在数据库中插入名称时，提交按钮被禁用，并且没有给出任何错误或重定向到另一个页面。 请帮忙。 我是bootstrap的新手。
<?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");
}
}
else{?>

<form id="contactForm" method="post" class="form-horizontal">
您正在对脚本进行大量验证。删除firstname以外的其他验证 我尝试了但仍需要两次，所以提交后，再次更改名字然后再次提交。不知道是不是因为你的formvalidation.js的代码
<?php
//include 'includes/db_connection.php';
if (isset($_POST['submit'])) {
$firstname = $_POST['firstname'];
$sql1 = "INSERT INTO student (firstname) VALUES ('$firstname')";
$res1 = mysqli_query($conn, $sql1);
if ($res1) {
echo 'succ';
// header("Location: successful_message.php");
} else {
echo 'fail';
// header("Location: valid_test.php");
}
} else {

您正在检查
if (isset($_POST['submit']))
{
而不是action="validate-input.php"写action=""
将操作留空，以便将表单提交给 文件的地址，即同一页。
