I read up on how to define a rootpath constant that is useable in all subpages when using a single page application.
Now my question is, how can i use the basepath in my scripts i point to in my form actions?
My problem is that i want to use a relative path, compared to where the script is located, in the "action" scripts so that the path will work no matter from where that file is called.
I tried using
dirname(__FILE__)
but as i use files in parent directories some levels up i ended up with something like
dirname(dirname((__FILE__))
and sometimes even another level up and i did not like the look of that.
After trying to to use a basepath constant i found out that it is not accessable in the scripts my forms are calling on form submit.
So my question is. How can i use a common basepath that works in the entire application? I was thinking about storing it in a session, but that seemed like a bad idea as it has no real place there.
Any advice would be appreciated, thanks in advance.
There is no common basepath for both the client- and the server-side of your application.
On the client side, all paths are relative to the current url or absolute which is relative to the base url / domain name.
On the server side your are dealing with the file-system.
So if your site root on the server-side ($_SERVER["DOCUMENT_ROOT"]) is something like /home/some-user/www and your form processor is located at /home/some-user/www/assets/inc/process-form-1.php, that is the exact path you need on the server-side (if you want to use absolute paths...).
However, on the client-side, your action would point to a relative path or an absolute path which in this case would be /assets/inc/process-form-1.php; an absolute path relative to the root of the web-server.
