constants / defined not working

[mfacer]

I'm trying a slightly different approach with a new site I'm making... I have files all over the place.. eg:

index.php will include "header.php" which in turn will include "config.php". This is where I set some constants, eg:

define('PATH',"http://localhost/blah/");
define('VERSION',"2.31");

in index.php when I include the header (in the same folder) I can use the constants... but if I am in say "files/process_form.php" and I include "../header.php" the file path for the header to include config.php is obviously wrong so the constants are not used.

How do they work, are they like sessions?? I'm getting slightly confused!! :bemused:

In header.php just use absolute filepath instead of relative.

include('/home/website/public_html/config.inc.php');

Sounds like a good argument for putting included files into directories which are in your PHP include path. 🙂

If necessary, you can also construct the absolute filepath on the fly using the contents of the $_SERVER array. This would also be more robust should the whole thing be shifted.
