URL Variables

[BulldogGC]

How do I find out is a URL variable is defined?

	<?	
		while(odbc_fetch_row($command)) {
			$name = odbc_result($command,1);
			$id = odbc_result($command,2);
				echo "<tr><td><a href='index.php?moreinfo=true&id=$id'>$name</a></td></tr>";
		}	
	?>

After the $name</a> part I want it to have an If/Then statement that goes "IF urlvariables.morinfo IS defined and url.id eq $id" a little red star shows up.

bu URL variables, I thik you mean GET variables. If that is th case ethen u can access them in this manner:

if (isset($GET['morinfo']) && $GET['id'] == $id) {
// SHow a lil red star
}
