The only way you are going to do that is by using javascript.

Otherwise it will call for a page refresh everytime and then you would lose them.

can you give example ?
i use it like this

Code:

<?php
foreach($query_add as $item)
{
if($item->nama_barang == "Lainnya")
{
?>
<Tr><td>
[removed]
document . write("&lt;input type='text' nama='kod_b'&gt;")
[removed]
</td>
&lt;?php
}else{
echo "<Tr><td>&lt;input type='text' nama='kod_b' value='$item-&gt;id_barang'&gt;&lt;/td>";
}
}
?&gt;

but it same like before, am i wrong ?
