我在“插入记录”中的 SQL 语句和一些 HTML 代码中遇到问题，如果我在编码时做错了，我已经提供了到 MySQL 的连接，然后查找了正确的代码用于将记录插入列。但似乎没有从中得到任何结果。

注册.php:

<?php
$servername = "127.0.0.1";

$username = "root";


$password = "redacted";

$db = "pre";

// Create connection

mysqli_connect("$servername","$username","$password","$db") or die(mysql_error());


// Check connection

mysqli_select_db("$db") or die(mysql_error());


  $fornamn = $_POST['fornamn'];

  $efternamn = $_POST['efternamn'];

  $kon = $_POST['kon'];

  $birthyear = $_POST['birthyear'];

  $smak = $_POST['smak'];

  $nationalitet = $_POST['nationalitet'];

  $epost = $_POST['epost'];
  $anv = $_POST['anv'];
  $losenord = $_POST['pass'];

$query = "insert into users(fornamn, efternamn, kon, birthyear, smak, nationalitet, epost, anv, pass)
 VALUES('$fornamn','$efternamn','$kon','$birthyear','$smak','$nationalitet','$epost','$anv','$losenord')";

mysqli_query($query) or die(mysql_error());

mysqli_close();

?>

我遇到了很多问题，不知道哪里出了问题。
