I believe I do what you are attempting to do, in pure PHP using a switch
statement and variables. It works, (check www.northpointless.org to see it
in action) but keep in mind my site is in early developement, so the menu
options aren't quite fleshed out at this time.:
function menu ($pos, $sub = "none", $sub2 = "none") {
global $PHP_SELF;
global $sess_auth;
switch($pos) {
case main:
print "<B><A HREF=$PHP_SELF>Home</A>";
print "<BR><A
HREF=$PHP_SELF?sub=Comm&action=Comm>Community</A>";
print "<BR><A HREF=$PHP_SELF?sub=JFF&action=JFF>After
Hours</A>";
print "</B>";
break;
case secondary:
switch($sub2) {
case WOS:
$wos = "<FONT SIZE=-1><B>Add Slander</FONT>";
break;
}
switch($sub) {
case Comm:
print "<B>Message Boards";
print "<BR>Mailing List";
print "<BR>Job Listings";
print "<BR>Member Directory";
print "</B>";
break;
case JFF:
print "<B><A
HREF=$PHP_SELF?action=wos&action_args=show&sub=JFF&sub2=WOS>Wall Of
Slander</B></A>";
if ($wos) { print "<BR>$wos"; };
break;
}
break;
}
}
