RandomPage

Overview

This allows you to create a random page include anywhere inside of a page. For example, you could have a random banner on a page.

    
    Markup('randpage','<include',
         "/\\(:randpage\\s*(.*?):\\)/e",
         "randomPage('$1')");

    function randomPage($opts) {
         $args = ParseArgs($opts);
         srand((float) microtime() * 10000000);
         $randPageIndex = array_rand($args['']);
         return "(:include " . $args[''][$randPageIndex] . ":)";
    }

Insert the following into your page:

 (:randpage Banners/Banner1 Banners/Banner2 Banners/Banner3 MyBanner/Thing:)

When that page is displayed it will include one of the pages given as arguments to the randpage directive.

For example:

(:randpage Banners/Banner1 Banners/Banner2 Banners/Banner3 Banners/Banner4
Banners/Banner5:)

Notes and Comments

One can now include a random page by using the (:pagelist:) markup:

(:pagelist group=Banners list=normal order=random count=1 fmt=#include:)

This is Banner 3
