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'];

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

send one variable:

http://myPmwikiSite.com/pmwiki/MyGroup/MyPage?x=blam(approve links)

or send multiple variables by separating them with an ampersand (&):

http://myPmwikiSite.com/pmwiki/MyGroup/MyPage?x=blam&y=blee&z=blech(approve links)

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:
http://www.pmwiki.org/wiki/Cookbook/EasyHttpRequests#example?x=blam&y=blee&z=blech
(note: this is not currently implemented on this page)

current x-var: {$urlVarX}

current y-var: {$urlVarY}

current z-var: {$urlVarZ}

this should then show up on your page:

current x-var: blam

current y-var: blee

current z-var: blech
