I use a function to create select boxes:
function make_select($fieldname,$options,$selected,$opt=) {
# make a select box with option text $opt
# $fieldname = name of html field
# $options = associative array of select options
# $selected = field key of selected item
# $opt = optional attributes, e.g., styles, etc.
$output.=\nselect name=\$fieldname\ $opt ;
foreach ($options as $key=$val) {
$output.=\noption value=\$key\;
if ($key==$selected) {
$output.= selected;
}
$output.=$val;
}
$output.=\n/select\n;
return $output;
}
By passing the previously selected item as $selected it will
automatically reselect the chosen item. For instance,
?php echo make_select(myfield,$options,$_POST[myfield]) ?
I've written similar functions for check boxes and radio buttons.
They've made form creation and handling enormously easier.

I am using PHP. I have a registration page where the user has to select his
country form a drop down list. If the username that the user selected for
himself exists in the database I am sending him back to the registration
form with all the fields completed with the values he previously entered.
This is easy to do for a textfield but how do I indicate on the drop down
list which country he originally selected?
Please help.
