Trying to position through an array based on date
Posted: Tue Jul 27, 2010 9:21 pm
Hi all,
I have an array of page content that displays content to a JCarousel slider. At the moment the first slide would be (code below) page_01.html, the 2nd slide page_02.html, third page_03.html etc.
Now what I am trying to do is setup this piece of code so that the content that is loaded into Jcarousel is determined by what date it is, so I need to be able to position like a starting point of the array based on date. Say its the 8th week of the year well I need to be able to make 'page_08.html' be the first content to load, page_09.html would be second, page10.html would be third etc and the preceeding pages (07, 06, 05 etc) would be left out of the content list.
I mean I coudl probably setup up 52 cases for an if statement but I have 52 content.html pages which would mean a LOT of code, just wondering if someone can help me figure out how to create something I am trying to do. Any help would be great. Here is my current array code:
