That's true, however there are a few ways to cheat :). For example, in
my form I have a State and Country popup menu. Rather than trying to
write code that selects the proper one to match the post data, I simply
create a new entry at the top:
<select name="state">
<?
if(isset($state)) {
$statename = GetStateName($state);
echo "<option selected value='$state'>$statename";
}
?>
<option value="">Select a state
<option value=AL>Alabama
This works because I've already verified the data. If the data doesn't
pass verification, it would be reset and would fail the isset($state)
test.
Otherwise, most form elements are pretty easy to assign values to.
