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, categories, tag pages, archives, and author listings.

function change_number_of_posts($query) {
	if ( ! is_front_page()) // Make sure it is not the front page
	$query->query_vars['posts_per_page'] = 20; // Change 20 to the number of posts you would like to show
	return $query; // Return our modified query variables
}
add_filter('pre_get_posts', 'change_number_of_posts'); // Hook our custom function onto the request filter

You can change this only for category pages for example with this code.

function change_number_of_posts($query) {
	if ( $query->is_category ) // Make sure it is a category page
	$query->query_vars['posts_per_page'] = 20; // Change 20 to the number of posts you would like to show
	return $query; // Return our modified query variables
}
add_filter('pre_get_posts', 'change_number_of_posts'); // Hook our custom function onto the request filter

The result is that you can set the global setting in the WordPress admin page to 10 posts, which affects the front page (index). You can then insert this code into functions.php and all other pages will display 20 posts.

Note: You do not have to modify your theme other than functions.php for this to work.

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. BEFORE: $allowedSites = array ( 'flickr.com', 'picasa.com [read] Keywords: domino blogger server

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 bug community database google skype xml

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. The old [read] Keywords: domino

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 [read] Keywords: admin domino google

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
