Hola delallave,
Prueba esto:
Código PHP:
while($value = mysql_fetch_array($result))
{
$domain_id=$value['domain_id'];
$domain_description=substr($value['domain_description'],0,70);
if ($domain_id==$_POST['domain_id']) {
$option_line=$option_line.'<option selected value="'.R4crypt($domain_id).'">'.$domain_descript ion.'</option>'."\n";
} else {
$option_line=$option_line.'<option value="'.R4crypt($domain_id).'">'.$domain_descript ion.'</option>'."\n";
}
Saludos.
