AUTHOR: Jens Zetterström
\\
----
==== INSTALLATION: ====
    
Put the code in **/frontend_render/** (for example in a file called **random_cp.php**).
<note tip>If the article content part contains replacement tags (for example {SITE}), they will not be replaced because code in /frontend_render/ is executed after those replacement tags already have been processed. To fix, put the code in content.article.inc.php instead. </note>

=== USAGE: ===

**{RANDOMCP:article_id}** //(where article_id is the id of the ARTICLE).//

=== RCS: ===

set article to invisible, but CPs to visible
