How to read PHP $_SESSION from PW when bootstrap is not an option

[Moebius]

I have situation like this.

Page 1:
https/www.domain.com/some_non_processwire_page.php
This page is out of my scope and it set some PHP session, e.g. $_SESSION['something']
There is no way that I can bootstrap PW in this page, I must leave $_SESSION['something'] as it is, so there is no option to bootstrap & and convert it to $session->something

Page 2:
https/www.domain.com/some-pw-page
This is normal PW templated page, full under my control.

I need to read $_SESSION['something'] from there.
I know PW has it's own $session object, but as I staed beofre, I can't bootstap PW from some_non_processwire_page.php and then do stuff only with PW $session

Is there any possible way that I can read $_SESSION['something'] from https/www.domain.com/some-pw-page

I found some topics about session here on forum, but none of this answers is solution for my situation.

Dobro vece,

You can try this in your template or _init.php:

$cookieFile = $_SERVER['DOCUMENT_ROOT'] . "/pw-boilerplate/site/assets/cookies/cookies.txt"; // adjust this
if(!file_exists($cookieFile)) {
	$fh = fopen($cookieFile, "w");
	fwrite($fh, "");
	fclose($fh);
}

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, 'http://localhost/pw-boilerplate/session.php'); // more about this below
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
curl_setopt($ch, CURLOPT_COOKIEFILE, $cookieFile); // Cookie aware
curl_setopt($ch, CURLOPT_COOKIEJAR, $cookieFile); // Cookie aware
$result = curl_exec($ch);
curl_close($ch);

$result will now show the value of your outside session.

pw-root/session.php does really only this:

<?php
session_start();
if(isset($_SESSION["outsidepw"])) {
	echo $_SESSION["outsidepw"];
}

This means that if your non-PW site creates a session named "outsidepw", you just output it to the browser, in a page that sits in the PW root (not inside site/templates). Since such PHP files at root-level know nothing about PW, you can do anything you want (they're not bootstrapping PW).

CURL will mimick a browser request, and that way you can get the external session var back into PW.

Just tested it out quickly. Instead of a full-fledged PHP app in root, I just created a PHP file that instantiates a session and declares a session value. But the main logic should still work, as long as you know the external session var...

Hvala Dragan,

I'll give it a try.
