Answer 1

The id is auto increasing, so you should remove id column in you insert sql. Also, the method you are using is dangerous, you should not totally trust what pass to you by other users in you website page, instead, you need to add filter functions.

Answer 2

You Query Should Look Like this. At Least in postgresql and MySql
$query = "INSERT INTO t_koperasi(id_koperasi,nama_koperasi,alamat,telp,hp,nama_cp,email,tanggal_fu,ket_fu,hasil_pembahasan,status) VALUES (
'".$id_koperasi."',
'".$nama_koperasi."',
'".$alamat."',
'".$telp."',
'".$hp."',
'".$nama_cp."',
'".$tanggal."',
'".$ket_fu."',
'".$hasil_pembahasan."',
'".$status."')"
;
You do not need to insert value into ID .Because ID expected to be the primary key with default value (auto increment).
Hope This works for you!

Answer 3

Simple remove id and ' ' . i hope work fine.
or
You just copy this code and past your project
<?php
include 'koneksi/koneksi.php';
if(isset($_POST['Submit'])) {
$id_koperasi = $_POST['id'];
$nama_koperasi = $_POST['nama'];
$alamat = $_POST['alamat'];
$telp = $_POST['telp'];
$hp = $_POST['hp'];
$nama_cp = $_POST['kontak'];
$email = $_POST['email'];
$nama_cp = $_POST['kontak'];
$tanggal = $_POST['tgl'];
$ket_fu = $_POST['ket'];
$hasil_pembahasan = $_POST['hasil'];
$status = $_POST['stat'];
$query = "INSERT INTO t_koperasi(id_koperasi,nama_koperasi,alamat,telp,hp,nama_cp,email,tanggal_fu,ket_fu,hasil_pembahasan,status) VALUES ('$id_koperasi',
'$nama_koperasi',
'$alamat',
'$telp',
'$hp',
'$nama_cp',
'$tanggal',
'$ket_fu',
'$hasil_pembahasan',
'$status')"
;
if (mysqli_query($con,$query)) {
header("location:index.php");
}else {
error_log( "This code has errors!" );
}
} include 'views/v_form.php';
