Tolong solusi dan koreksinya kak, ini scriptnya :

Ini Di file prosesnya :

<?php
include('../koneksi.php');
$guru = $_POST['id_guru'];
$mapel = $_POST['id_mapel'];
$nis = $_POST['nis'];
$kelas = $_POST['id_kelas'];
$jurusan = $_POST['id_jurusan'];
$uh = $_POST['uh'];
$uts = $_POST['uts'];
$uas = $_POST['uas'];
$na = ($uh + $uts + $uas)/3;

    $query = mysqli_query($koneksi, "insert into nilai values('',$guru','$mapel','$nis','$kelas','$jurusan','$uh','$uts','$uas','$na')") or die (mysqli_error($koneksi).$query);

if ($query) {
	echo "<script>alert('Proses Berhasil! Silahkan Menuju Admin')</script>";
