Fresh set of eyes for a simple problem

Carl_Conrad

I have a page which includes another page (the included page generages a random image, which really isn't important). In the page that calls the random image generator, I have a directory_depth variable set up so that I can use the same templates and just have the directory depth set in front of links.

For one particular page, I have the directory_depth variable set to ../ which should take me to the directory where I need to be when combined with the rest of the link. The problem: it doesn't work, but when the ../ is hard coded in, it does. I'm pasting both the working include and the non working include below. Your thoughts would help me out a lot...

WORKING (hard coded ../)

<?php include('../randimg/randomimage10.php'); ?>

NOT WORKING (uses directory_depth to print ../)

<?php include($directory_depth . 'randimg/randomimage10.php'); ?>

What I wind up doing is this:

define(_DOCROOT_, "/var/www/html/project");

Then:

include_once(_DOCROOT_ . "/include/file.php");

After dealing with including files in other directories with the possibility of those files also including files, using a literal path is usually a good option.

Thanks Wynder. I'm very new (and I'm sure you saw this one coming 😉), but where exactly do I use that at? In the page that I need to include (randomimage3.php) or in the page that I'm calling it in. That looks like it will solve my problem though. The error I'm getting is:

Warning: file(images2.txt): failed to open stream: No such file or directory in /home/paperrob/public_html/randimg/randomimage2.php on line 11

So nice to have direction. I've spent A LOT of time trying to figure out why it won't work...

You'll want to use it in the file you want to include the second file into, before you include it.

That way it'll will read the definition, then use it in the require/include. 🙂

I work with large projects and, in using sessions and variables that need to contain the document root and URL root, I commonly setup a session.php that starts the session, has all of my defines, and other thing of that nature and that file is the first file included in every other file in the project. That's the only one that needs to be included with the full path since define hasn't been processed yet.

May sound a bit confusing, but just try to remember that everything is processed, for the most part, in order.

G'luck.

Thanks a lot. I really appriciate it...
