mau tanya gan kenapa ketika ane upload script seperti ini di hosting

$op = $_GET['op'];



if ($op == "order")

 {

if(is_array($_POST['checkbox']))

{

foreach($_POST['checkbox'] as $idmovie){ 

$sql1="INSERT INTO detorder (idorder, tgl, idmovie, judul, size, hdd, jenis, status) VALUES ('".$idp."', '".$_POST['tgl']."', '$idmovie', '".$_POST['judul'][$idmovie]."', '".$_POST['size'][$idmovie]."', '".$_POST['hdd'][$idmovie]."', '".$_POST['jenis'][$idmovie]."', 'N')"; 

$hasil = mysql_query($sql1);

}

} else echo "[removed]alert('Bukan Array. ".$_POST['checkbox']."');[removed]";

$_SESSION['nohp'] = $_POST['nohp'];

$_SESSION['nama'] = $_POST['nama'];

$_SESSION['alamat'] = $_POST['alamat'];

$_SESSION['idp'] = $idp;



echo "[removed]alert('Silahkan Lengkapi Proses Selanjutnya.'); [removed] = 'checkout.php';[removed]";

}

kemudian ada form yang didalamnya ada element checkbox

<table width="100%" border=1px bordercolor="#FF0000" style="border:0.5px solid red;">

 <tr height="50px" bgcolor="#FF0033" style="color:#FFFFFF">

 <th align="center">PESAN</th>

 <th align="center" width="40%">TITLE</th>

 <th align="center">TYPE</th>

 <th align="center">SUBTITLE</th>

 <th align="center">SIZE</th>

 <th align="center">RELEASE</th>

 </tr>

 <?php

 

 $query1 = "SELECT * FROM list WHERE jenis = 'HD' ORDER BY id ASC";

 

 $hasil1 = mysql_query($query1);

 while ($data1 = mysql_fetch_array($hasil1))

 {

 echo "<tr>

 <td><input type ='checkbox' name='checkbox[".$data1['id']."]' id='checkbox[".$data1['id']."]' value='".$data1['id']."'></td>

 <input type='hidden' name='judul[".$data1['id']."]' value='".$data1['judul']."' />

 <input type='hidden' name='size[".$data1['id']."]' value='".$data1['size']."' />

 <input type='hidden' name='hdd[".$data1['id']."]' value='".$data1['hdd']."' />

 <input type='hidden' name='jenis[".$data1['id']."]' value='HD MOVIE' />

 <td>".$data1['judul']."</td>

 <td align='center'>".$data1['type']."</td>

 <td align='center'>".$data1['subtitle']."</td>

 <td align='center'>".$data1['size']."</td>

 <td align='center'>".$data1['release']."</td>

 </tr>";

 $no++;

 }

 mysql_free_result($hasil1); 

 ?>

 </table>

ketika submit, array dari checkbox gak mau tersimpan (ketika pilih id yang besar), padahal kalau di localhost bisa tersimpan value arraynya

mohon pencerahannya
