[jQuery] GET MULTIPLE VALUE FROM jQuery for external file loader

[dr.emi]

Hi!
I use jQuery Loader Content to auto complete the state select tag.

function loadContentKabupatenKotaDiploma(id) {
        $("#contenPanKabupatenKotaDiploma").hide();
        $("#contenPanKabupatenKotaDiploma").load("../dre-includes/
url_pendidikan/findKabupatenKota.php?id="+id+"", '',
callbackKabupatenKotaDiploma);
}
function callbackKabupatenKotaDiploma() {
        $("#contenPanKabupatenKotaDiploma").show();
}
$(document).ready(loadContentKabupatenKotaDiploma(id));





then here are the html code:
<label>Propinsi</label>
<?
$query="SELECT * FROM master_propinsi";
$result=mysql_query($query);
?>
<select class="input" name="id_propinsi_pendidikan[]"
onChange="loadContentKabupatenKotaDiploma(this.value)">
        <option value="">Pilih Propinsi</option>
        <?
        while($rows = mysql_fetch_array($result))
        {
        ?>
        <option value="<? echo $rows['id']; ?>"><? echo $rows
['nama_propinsi']; ?></option>
        <?
        }
        ?>
</select>
<div class="spacer">&nbsp;</div>
<div id="contenPanKabupatenKotaDiploma">&nbsp;</div>

I create a script for external file: findKabupatenKota.php

<label>Kabupaten/Kota</label>
<select class="input" id="id_kabupaten_kota_pendidikan"
name="id_kabupaten_kota_pendidikan[]">
<option>Pilih Kabupaten/Kota</option>
<? while($row=mysql_fetch_array($result)) { ?>
<option value=<? echo $row['id']; ?>><? echo $row
['nama_kabupaten_kota']; ?></option>
<? } ?>
</select>

AND now I want to get the value of id_kabupaten_kota_pendidikan[].

I try this way for POST FORM Action:

for($d=0;$d <= count($_POST['nama_pt']);$d++)
                {
                $jQueryKabKPendidikan[$d] = "<script>$
('[...@name=id_kabupaten_kota_pendidikan]')[$d].val(); </script>";
                if(!empty($_POST['nama_pt'][$d]))
                {
                mysql_query("INSERT INTO `data_pendidikan_terakhir` (
                `id_peserta` ,
                `id_jenjang` ,
                `tahun_lulus` ,
                `id_jurusan` ,
                `nama_pt` ,
                `id_propinsi` ,
                `id_kabupaten_kota` ,
                `tanggal_input`
                )
                VALUES (
                '".$noUrut."',
                '".clearString($_POST['id_jenjang'][$d])."',
                '0000',
                '".clearString($_POST['id_jurusan'][$d])."',
                '".clearString($_POST['nama_pt'][$d])."',
                '".clearString($_POST['id_propinsi_pendidikan'][$d])."',
                '".clearString($jQueryKabKPendidikan[$d])."',
                '".thisTime."')");
                }

                }

The result is $jQueryKabKPendidikan[$d] = 0;

Well... do you have one idea to get multiple value from a selected
field ? and is combination of jQuery + PHP a better way ??? Or I must
use a complete Ajax Post Action without PHP ?
