I've run into a problem that I can't resolve with the docs because there's no usage examples (I know, I know...but I can't write it if I don't know it). D6. I need to create a file. Seems simple. But I can't determine what combination of variables give me a good path. $file_directory_path gives me sites/default/files which is great if I have something to append it to, such as /users/myusername/public_html/mydomain.com/drupal but in looking at the descriptions of the various file api functions/vars, I don't seem to see one that does that as opposed to checking this, verifying that, etc.

Thanks, Lee. Yes, that's what I did. It seems, though, that there should be a Drupal function or global to avoid having: $fn = $_SERVER['DOCUMENT_ROOT'] . '/' . $file_directory_path() . '/myfilename';
Actually, it's worse...I forgot $base_path (which makes a difference if you're drupal root is a subdirectory)... so it's $fn = $_SERVER['DOCUMENT_ROOT'] . $base_path . $file_document_path() . '/myfilename';
It's a bit of a pain to learn but you'll save yourself some headaches by using Drupal's file functions in includes/file.inc for doing path handling. If you're trying to create a file in Drupal's files directory use: file_create_path('the/desired/filename.ext'); which give you a path relative to Drupal's root. If you need the full path from the server root you'll need to use PHP's realpath() which only works with existing files so you'll need to use: realpath(file_directory_path()) . 'the/desired/filename.ext'; Once you get some data saved in there you can use file_create_url() to get a URL for the file that you can send out to visitors so they can download the file. andrew On Fri, Nov 6, 2009 at 12:57 AM, Jeff Greenberg <jeff@ayendesigns.com> wrote:

When coding realpath(file_directory_path()) . 'the/desired/filename.ext'; Isn't there an assumption that file_directory_path() is relative to the current path? Otherwise how does realpath know where it's intended to go? Which kind of brings me back to the original question, of file_directory_path being relative to...what? Will my current position, when invoking file_directory_path() always be relative to the Drupal root, even if the current page has a path that is a subdirectory off the Drupal root?

file_directory_path() is relative to the Drupal root. PHP's realpath() function is relative to the "current" directory. If you have not run chdir() anywhere, it appears that PHP sets the current directory to the directory of the original PHP file (I think?), which would be the index.php file of Drupal, which is also in the Drupal root. So it does work, somewhat magically. Incidentally, I'll just mention that the previous suggestion of $_SERVER['DOCUMENT_ROOT'] . $base_path . (whatever) is not going to work in all situations, since depending on the Apache config, the directory for some web spaces may not even be under the server's document root. For instance, on my test box the doc root is /var/www/, but I have Apache configured so that the URL http://localhost/~xyz maps to /opt/www/xyz. realpath(), on the other hand, works perfectly in this case. You can also do something like realpath( drupal_get_path('module', 'mymodulename')) if you need to reference a file in your module directory for some reason (e.g. in a test). --Jennifer -- Jennifer Hodgdon * Poplar ProductivityWare www.poplarware.com Drupal, WordPress, and custom Web programming
