Get file path relative to index.php

[DrQuincy]

I've got some code that gets run from various locations and the file path is stored in PW (since it varies depending on the environment). I want to be able to store a single setting that works across all environments. The problem is sometimes it's called from init.php and other times from a template. So if my setting is ../data/, this will result in things like:

/MyPWSite/site/templates/../data/
/MyPWSite/site/../data/

I.e. different locations when the data is always in the same place.

What would be ideal is if I can get a file path that is always from the main index.php folder (/MyPWSite/ if you go by the above example) regardless of what point in the application it's called. I've searched for this and can't find it. Is there a variable I can use?

I've not really tested it but in PHP something like this would do it:

dirname($_SERVER['SCRIPT_FILENAME'])

I just wondered if there was already something in the PW API.

Thanks. ?

You can set your own path to your data directory ?

https://processwire.com/api/ref/paths/

or you can use the root directory:
$urls->root
Site root: / (or subdirectory if site not at domain root)

Ah, interesting, thanks!

Ah, yes, this is just what I want, thanks.

$paths = $config->paths;
$paths->set('myData', 'my-data/'); // Relative link
echo $config->paths->myData; // /Absolute/path/to/PWSite/my-data/

Thanks. ?
