Random Content part from a given Article ID
Posted: Tue 23. Oct 2007, 22:49
hi all, I realise that SHOW_CONTENT is now built in and I use it/ recommend it thoroughly 
what I have spent a few mins adapting it to do a small job i need... show a random content part from a given article - think of it as a 'random quotes' script on steroids - the steroids are that it can show any content part not just plain text.
OK- a small adaptation to Jens's script means a big thanks and all credit go to him.
A working version can be seen http://www.teensunitefightingcancer.org as the 'QUOTES' box in the {RIGHT} column - this is a live site so no funny business please!
As it's a replacement tag, you know the procedure by now... save this code as a file name in template/inc_script/frontend_render/randomCP.php
then use it by adding the article ID in the tag as per the script header blurb... {RANDOMCP:xx}
hope it helps, pSouper

A 'minor bug-ette' is that I had to comment out the line that checks if the article end date has past but I can't figure out why it does not work - basically, with the line in it only show the same CP over & over again. any help with this would be very nice too

// {SHOW_CONTENT}
// AUTHOR: Jens Zetterström
// ADAPTED BY: pSouper
// DESCRIPTION: Shows a random content part from within a given article (you supply the article ID - it show a random content part from within that article).
// INSTALLATION: Put the code in frontend_render (for example in a file called random_cp.php)
// Note: 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.
// USAGE: {RANDOMCP:article_id}
// where article_id is the id of the ARTICLE.
