            </span></div></td>
    </tr>
  </table>
</form>

dan ini proses insert data ke tabel lain

<?php

include "config.php";


$id = $_POST [chk];
$banyaknya = count($id);

if($_POST['submit'])
{

for ($i=0; $i<$banyaknya; $i++)
{

$sql = "insert into kandidat (nip) value ('$id')";
$trus = mysql_query($sql);

}

if ($trus)
{
print "Record berhasil diInsert<br>";
print "<a href=data_kandidat.php>Klik disini untuk kembali</a>";
}

}

?>

<?php
 
include "config.php";
 
 
$id = $_POST ['chk'];
$banyaknya = count($id);
 
if($_POST['submit'])
{
 
for ($i=0; $i<$banyaknya; $i++)
{
 
$sql = "insert into kandidat (nip) value ('".$id[$i]."')";
$trus = mysql_query($sql);
 
}
 
if ($trus)
{
print "Record berhasil diInsert<br>";
print "<a href=data_kandidat.php>Klik disini untuk kembali</a>";
}
 
}
 
?>
