You need to track the current customer in a hidden form field and do
something like this:
if(isset[$_POST['current_customer'])){ //someone pushed submit
if($_POST['customer'] == $_POST['selected_customer']){
//same customer check if we have a new conf
if(isset($_POST['conf'])){
$selected_conf = $_POST['conf'];
}else{
$selected_conf = $database_conf;
}
}else{
$selected_conf = $database_conf;
}
else{ // first run so use defaults from database
$current_customer = $database_cutomer;
$selected_conf = $database_conf;
}
then in your select loops use $current_customer and $selected_conf to
determin when to output "selected"
Probably need to tweak the above but it is a start :)
