Way back, I wrote the tutorial on how to create a pagination scheme similar to the one that Digg uses. The code in the tutorial was meant to educate readers on how the algorithm works.

Meanwhile, I was using completely different code for my own projects. Typically I put all of the pagination code into a function (or PHP class), which makes it much easier to use in practice. Now I’ve made available a version of this function, which people should look to first if they want a quick implementation.

• Download the PHP code for the function here: diggstyle_function.txt.
• To use it make a function call like getPaginationString($page, $totalitems, $limit, $adjacents, $targetpage, $pagestring);.
• $page is the current page number
• $totalitems is the total number of items in the set. You usually get this from a SQL query.
• $adjacents is the number of page links to put adjacent to the current page.
• $targetpage is the URL you want to point to. e.g. index.php
• $pagetext is the string used to append the page variable to the URL. e.g. ?page= or &p=
• Use this style sheet.

Read the tutorial for more help and to see an example. For a real-live example, check out my Wine Log.

Also, Mis Algoritmos is at it again with a digg-style pagination plugin for Wordpress based on this code.

Earlier in the year, I wrote a tutorial on how to create pagination similar to Digg’s. The article focused on the basic algorithm for displaying the pagination, and there was definitely some opportunity for improvement in its implementation.

Well, the improvements are in. We have a modularized PHP version and a Perl version. See the updated pagination demo page for details.

Some people were interested in seeing the code I used to create the pagination for WineLog, which was based on the style of pagination used on sites like Digg and Flickr. I’ve put together a little demo which should help out anyone who is trying to create the same effect on their site.
