Mohon bantuannya, saya bingung melakukan get textboxt sebagai nama tabel database yang ingin digunakan.
<?php //proses-ajax.php
include 'koneksi.php';
$nim = $_GET['nim'];
$nama = "mahasiswa";//mau dibikin $nama = $_GET['namatabel'];
$query = mysqli_query($koneksi, "select * from $nama where nim='$nim'");
$mahasiswa = mysqli_fetch_array($query);
$data = array(
            'jurusan'   =>  $mahasiswa['jurusan'],
            'alamat'    =>  $mahasiswa['alamat'],);
 echo json_encode($data);
?>

ini form ajaxnya
<!DOCTYPE html> <!--form-ajax.php-->
<html>
    <head>
        <title>Ajax Jquery - Belajarphp.net</title>
    </head>
    <body>
        <form action="">
            <table>
                <tr><td>NIM</td><td><input type="text" onkeyup="isi_otomatis()" id="nim"></td></tr>
                <tr><td>NAMA TABEL</td><td><input type="text" id="namatabel"></td></tr>
                <tr><td>JURUSAN</td><td><input type="text" id="jurusan"></td></tr>
                <tr><td>ALAMAT</td><td><input type="text" id="alamat"></td></tr>
            </table>
        </form>
        <script src="https://ajax.googleapis.com/ajax/libs/jquery/1.12.4/jquery.min.js"></script>
        <script type="text/javascript">
            function isi_otomatis(){
                var nimi = $("#nim").val();
                $.ajax({
                    url: 'proses-ajax.php',
                    data:"nim="+nimi,
                }).success(function (data) {
                    var json = data,
                    obj = JSON.parse(json);
                    $('#jurusan').val(obj.jurusan);
                    $('#alamat').val(obj.alamat);
                });
            }
        </script>

maaf gan, saya mau tanya, semisal saya punya tabel akun (id_akun (01,02), jenis_akun (pendapatan,pengeluaran), keterangan (kas desa,pembetulan jalan)).
di form saya punya 2 combobox, combobox 1 ada data: bukti bank masuk, bukti bank keluar (bukan data dinamis). semisal pada combobox 1 saya pilih bukti bank masuk, maka pada combobox 2 akan menampilkan data hanya berdasarkan jenis_akun pendapatan. jika combobox 1 saya pilih bukti bank keluar, maka pada combobox 2 hanya akan menampilkan data jenis_akun pengeluaran.
Moho bantuannya gan terima kasih
