[KLUG Programming] variable not being posted?

[Dirk Bartley]

I decided to work a little bit on my library project.  Attempting to get
it working on a RH9 machine I have run in to a snag.  For a url like


http://localhost/librarydb/title.php?title_id=46

the variable title_id is not being set.  Most configuration parameters
are left unchanged from default.

if ($title_id != 0) {
	do stuff here
}
else{ echo("no title_id"); }

with this as the url, the echo command occurs.

I'm confused.  Is php only allowing session variables to work and not
posted variables?
