Shiloh,
I'm kind of a latecomer here, but on my system, this works:
<?
if(isset($county_id)) {
print "<p>COUNTY ID: $county_id<br>\n";
} else {
} print "No County ID<br>\n";
?>
<p>
<a href="<?= $PHP_SELF ?>?county_id=17089">17089</a><br>
<a href="<?= $PHP_SELF ?>?county_id=99999">99999</a>
Can't think why you wouldn't be able to access that value unless you're
accidently clearing it before checking it. If you're trying to access
$county_id from inside a function, though, you'll need to declare it as a
global so the function won't think you're referencing a local variable by
the same name, i.e.
function process_submit() {
global $county_id;
print "ID: $county_id<br>\n";
}
