我一直在提交表单输入或尝试这样做我在这个PHP的末尾获得了404这个PHP它在php snippit的顶部我不确定这是否是问题的线索。我有与insert.php关联的操作我不确定发生了什么。给我的一切看起来都是正确的。但显然不是。我确保header('location: index.html')是正确的。正如另一篇文章所说。这是我的代码

PHP 

<?php echo $_SERVER['PHP_SELF']; ?>

我在url idk中得到它，如果它有助于其余的是inser.php代码。

<?php
$servername = "localhost";
$username = "Placeholder";
$pass = "FakeForShow";
$dbname = "sign up new";


$fullname=$_POST['fullname'];
$username=$_POST['username'];
$email=$_POST['email'];
$password=$_POST['password'];
$codelangs=$_POST['codelangs'];

// Create connection
$conn = new mysqli($servername, $username, $pass, $dbname);
// Check connection
if ($conn->connect_error) { 
    die("Connection failed: " . $conn->connect_error);
}

$sql = "INSERT INTO newusers (fullname, username, password, email, codelang)
VALUES ( '$fullname', '$username', '$email',  '$password', '$codelangs');";

if ($conn->query($sql) === TRUE) {
    header("location: index.html");
} 
else {
    echo "Error: " . $sql . "<br>" . $conn->error;
}

?>

您的数据库连接应与此类似。

$s = 'localhost';
$u = 'root';
$p = 'yourUsername';
$d = 'yourPassword';
$mysqli = new mysqli($s, $u, $p, $d);

检查是否先点击了屁股。

if(isset($_POST['insert'])){

执行这样的错误检查，你需要添加到这里这是非常基本的。

$fullname=$_POST['fullname'];
$username=$_POST['username'];
$email=$_POST['email'];
$password=$_POST['password'];
$codelangs=$_POST['codelangs'];   
$alert = '';    
$errorFullname = '';
if($_POST['fullname'] == '' || $_POST['username'] || $_POST['email'] || $_POST['password']){
if($_POST['fullname'] == ''){$errorFullname "Cannot be empty.";}//and so on...
$alert = "All fields are required.";} else {

如果没有插入错误。在插入密码之前加密密码。

$hashedWord = password_hash($password, PASSWORD_BCRYPT, array("cost" => 17));
$insertdata = $mysqli->prepare("INSERT INTO  newusers (fullname, username, password, email, codelang) VALUES('"$fullname"', '"$username"',  '"$hashedWord"', '"$email"', '"$codelangs"') ");
$insertdata->execute();
$insertdata->close();      
header("location: index.html");
}
}
include 'YourHtmlPage';

您可以像这样调用错误消息。

<div class="form-group">
<label for="login_email" class="sr-only">Full Name</label>
<input class="form-control input-lg" id="fullname" placeholder="Full Name" required="required" name="fullname" type="text">
</div>
<div><?php echo $errorFullname; ?></div>

您可以使用类似的方法检查哈希密码。运行选择并将其与键入的内容进行匹配。

password_verify($passwordTheyTyped, $YourHashedPassFromTheDatabase);

希望它有所帮助。

            <!-- Other form elements-->
            <button method="POST" type="submit" class="btn btn-lg btn-primary btn-block ladda-button" data-style="zoom-in" type="submit" name="insert">

            </button>
        </form>

    </body>

PHP代码：insert.php 

<?php
$servername = "localhost";
$db_username = "DB_USER_NAME";
$db_pass = "DB_USER_PASSWORD";
$dbname = "DB_NAME";

$username = $_POST['username'];
// Other POST elements

$conn = new mysqli($servername, $db_username, $db_pass, $dbname);

if ($conn->connect_error) {
    die("Connection failed: " . $conn->connect_error);
}

$sql = "INSERT INTO newusers (username) VALUES ('$username');";

if ($conn->query($sql) === TRUE) {
    header("location: index.php");
} else {
    echo "Error: " . $sql . "<br>" . $conn->error;
}
?>

您可以根据自己的要求添加更多表单元素，Javascript Validations等。
