How can I pass and retrieve a page variable in pmwiki via a URL?

Description

A simple way to pass and retrieve page variables via a URL (HTTP Requests).

Sending & Requesting Variables via HTTP Requests
1. Paste the following (or something similar) in your config.php:

      //// GET VARIABLES FROM URL ////
      $FmtPV['$urlVarX'] = $_REQUEST['x'];
      $FmtPV['$urlVarY'] = $_REQUEST['y'];
      $FmtPV['$urlVarZ'] = $_REQUEST['z'];

      # This method is critically insecure, it allows PHP code injection
      see: PageVariables and recipe Cookbook:HttpVariables for a better way. Siegfried Seibert (2015-12-19)

2. Then, if you'd like to pass a variable to a page, you can add it to your URL as such:

3. Finally, request the variable(s) by calling the PageVariables {$urlVarX}, {$urlVarY}, {$urlVarZ} on your PmWiki page.

By clicking this link to this current page (notice the appended variables), the variables would show up below:

(note: this is not currently implemented on this page)

this should then show up on your page:
