For example, to access a page in my search folder, I have to write:
mywebsite.tld/search/searchJob.php
I don't want users to have to write down folder structure and whatnot. What can I do to change this?
OR, is there a better way to organize my files? Because I'm only two pages in and I decided to move some files and got lost in the hierarchy (that's why I moved them like in the picture).
With the Apache web server, you could use mod_rewrite to beautify the URLs so that users don't have to type in everything. For example, users open mywebsite.tld/search/
and the request will be processed by mywebsite.tld/search/searchJob.php
without the user noticing it. This has another big advantage: You can organize the files as you want, and change the file names arbitrarily - you'll only have to change the URL mapping when you move or rename a PHP file.
As an aside: Users will almost never type in a full URL, normal users click through the main page or use enhanced address bars (like the Firefox address bar which shows history items) to open a web page.
