[PHP] question on parameter specification in href tag
Hi, I want to set a link like a href=http://www.anyurl.com?mypar=17color=red; ... into my HTML file; that works fine. But if I specify a hex color like #CC instead of red, a href=http://www.anyurl.com?mypar=17color=#CC; ... the color is ignored (probably because # starts a PHP comment). Is there any workaround for this problem ? Thanks and Regards Xaver -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Hey, X;
Actually, it's skipped because it's seen as a page anchor. That's
a client-side only thing, and the browser would then be looking for:
a name=CC id=CC/a
Instead, skip the hashmark:
a href=http://www.anyurl.com/?mypar=17color=CC; ...
and have it parsed similarly to this:
?php
if(strlen($_GET['color']) == 6
preg_match('/[a-f0-9]{6}/i',trim($_GET['color']))) {
// Color is a legitimate HTML hexadecimal color
$_GET['color'] = strtoupper($_GET['color']); // Set upper-case
} else {
// Color is not legit, was not supplied, or this may be a lame
hack attempt
$_GET['color'] = 'CC'; // Force default color
}
$color = '#'.$_GET['color'];
?
