Increasing the number of posts per page on category, tag, and archive pages in WordPress
Thu, Aug 18th 2011 12:10a David Killingsworth In WordPress, you can set the number of pages to display per page in the Administration settings. This is set in Admin/Settings/Reading.
The issue with this is that this is a global setting. If you would like to set a different number of posts to display on the front page than on the category page, you can do it by adding this code to functions.php in your theme.
The following code displays 20 posts per page on all pages that are not the front page (index). This includes search results, categori [read] Keywords: admin

Zero day vulnerability in many WordPress themes
Wed, Aug 3rd 2011 10:24a David Killingsworth Mark Maunder announced a zero day vulnerability in many WordPress themes yesterday here on his blog.
If you use any third party WordPress themes, you should check your server for the presence of timthumb.php or thumb.php. It is reported that several theme marketplace websites host common legitimate themes that utilize this library.
The fix is to remove any allowed sites from the thumb.php or timthumb.php files as recommended below.

WordPress XML Sitemap Plugin Review
Tue, Aug 2nd 2011 6:11p David Killingsworth I have been building quite a few sites with WordPress lately. WordPress has quite a long list of 3rd party plugins developed for various tasks and functions.
One downside to this is that there are several redundant WordPress plugins for common tasks, and their plugin search mechanism which is located at http://wordpress.org/extend/plugins/ is somewhat difficult to use.
I tend to search for the most installed or popular plugins and use the hive mind’s collective research to choose which plu [read] Keywords: domino

How to display nicely formatted PHP code in a WordPress post
Thu, Jul 21st 2011 12:11a David Killingsworth I’ve been struggling for a while about how to embed PHP, HTML, or CSS code into WordPress posts so that they look good and are easy to understand.
I found this list of 12 WordPress Plugins to Display and Highlight Code.
I researched a few of them and finally settled on SyntaxHighlighter Evolved, which was simple to install, easy to use with short codes, formats nicely, and seems to have a large existing user base.
In your posts, you can simply use [php] and [/php] shortcodes around your ac [read] Keywords: domino

Updating Price PHP print statements in Ubercart
Tue, Jul 19th 2011 12:11a David Killingsworth Recently, I updated an Ubercart shopping cart system on Drupal that was very out of date.
After the upgrade, the list price on the product pages had too many zeros. It looked like this.
MSRP $ 49.99000
After a bit of research, I learned that Ubercart has been updated to include more decimal places to accommodate more International currencies.
I took a look at the node-product.tpl.php template and found that the print statement for the list price was using the out of date print statement.

How to dynamically set Facebook Opengraph Meta tags in WordPress headers
Fri, Jul 15th 2011 7:14a David Killingsworth I recently developed a WordPress website where it was important that some pages could be liked and show up on a user’s Facebook status. The front page also had a Facebook fan page like box. This is getting to be pretty much the standard for most websites.
Setting up the placement of the buttons is pretty trivial. This guide shows you how to generate the widget code for the fan page like box, and this guide shows you how to generate the widget code for the like/recommend button.

Theming fields in Drupal 6
Wed, Jul 6th 2011 11:14p David Killingsworth I needed to figure out how to theme a field in Drupal 6. The use case was that I wanted to field to be a URL. This is pretty simple and straightforward by using the CCK Link module, which is a sub-module of CCK.
I was able to input my URL, such as http://www.symetrikdesign.com with no problem, and the CCK display options are pretty good. However, I wanted to strip the “http://” part on the output display, but have the link remain the legitimate link of http://www.symetrikdesign.com

Getting the Delicious bookmarks add-on to work with Firefox 5.0
Wed, Jul 6th 2011 10:14p David Killingsworth I figured out a simple trick to make the Delicious bookmarks Firefox add-on work after upgrading to Firefox 5.0.
This assumes that you previously had the Delicious bookmarks add-on working in Firefox 3.6.x and you have just upgraded to Firefox 5.0 – which disables the add-on and states that it is incompatible with Firefox 5.0

How to format line breaks in custom fields in WordPress
Wed, Jul 6th 2011 7:13p David Killingsworth I was working on a WordPress project where I needed to create some custom fields and format them for the user. I wanted to be able to create those fields so that the user only had to put a few bits of text into the fields and be done with it without having the need to know any HTML formatting.
I had this working fine for two fields called price and dimensions. The issues was that the output is a line of text, so all of the items were being displayed on one line and then wrapping to the next line [read] Keywords: domino
