Tutorials Intro

These tutorials reflect personal projects while practicing of new tools, ideas, techniques and technologies. They can not be used on their own as a final solution for any website.

I will be using xHTML, CSS and PHP in most of the tutorials so a basic understanding of each will be ideal but not a requirement if you work each tutorial from the beginning. I will also be making use of the jQuery javascript API for effects, AJAX and loads more.

My personal favourite has got to be the versatile and highly scalable php Smarty Template Engine, so almost everything I build uses it. I'm not on my own in working with and trusting the smarty template engine, there are loads of large names out there using it, Jamroom, XOOPS CMS, Movable Type, WHMCS, Serendipity, CMS Drupal to name a few, go to Smarty's Resources page for more.

/lib/Pager.class.php

/*
The following are tha steps in the Pagination class
How many rows?
How many pages?
Number rows devided by entries per page, ceil() will round the number up.
What page are you looking at, $currentpage?
and lets make sure we are not trying to browse more or less than the available pages.
Using the information we have collected, lets get our pages information
Assign values to smarty variables and templates for use as smarty functions
