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.="\n<select name=\"$fieldname\" $opt >";
foreach ($options as $key=>$val) { $output.="\n<option value=\"$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.
