I don't need response back to ajax. I need to process variable then in an another.php page.
I have "select" html element which fires function on change event (first code), to send an variable to an another.php. And then with an link I am migrating to that another.php when is needed from header.php. And i would like to see that variable, but i see "1". (check other my code)

OK. Can't really follow your logic. Do you have a link to your page so we can see it live. You may also want to post up the full code for the 2 pages user.php and the one with the AJAX call on.

My project tree:
In header.php i have html with "select" element. On change event of "select" , code in JS_file uses function "saveToProjectsListF()"
to send variable to another.php.
And on header.php i have a link to another.php. When i need then, i am going to my another.php, and there i need to see my "$actualproject" variable.
Maybe You can show me an yours example how you are sanding an variable to an php page.
project_folder
js_folder
JS_file.js
sub_folder
header.php
another.php

OK. I think I can see what your problem is.
When you change the <select> the actualproject variable is POSTed to the user.php page via AJAX. That's it! It doesn't keep that variable in that page for later use. If you then click on a link to user.php page, then the variable won't be available because you haven't POSTed it to the page - you've just visited the page with a normal link. The variable that you'd previously POSTed has been lost.
If you want to keep thr variable for later use then you would need to store it somewhere when you first POST it. Probably the simplest solution is to store it in a session variable.

Success. Thank you.
I see now the wanted variable. After doing final edits
lover-under some other code will stay question for now. But maybe i should take it as a fact and don't think about it any more.

"checks to see whether or you're not you're POSTing to the file"I did move yours code to the very top of everything. Why it was not working ,when the code was

You say you're only seeing "1" as the echo, but nothing in your code shows how you're getting that. You're not handling the response in your AJAX call, so where exactly are you getting the "1" displayed?
