Use latest jQuery from CDN in WordPress

WordPress is shipped with a current jQuery version by default. When you update your WordPress core and there’s a new version of the jQuery library that is used in the package, it will be updated, too. But you might have reasons not to update your WordPress core, want to use an outdated version of jQuery, or use the jQuery library hosted on a content distribution network (CDN). Google is hosting jQuery and other libraries publicly that you could use and include in your WordPress theme.

Shared functions.php across WordPress multi-sites

Ever wondered how you could use a shared functions.php in a WordPress multisite (WPMU) environment?

Make your WordPress gallery link to a custom image size

Using the WordPress gallery shortcode and linking the gallery items to its media source, WordPress will always create a link to the full size image. For a project I needed to change this behaviour since the full size images uploaded by editors will usually be too large to be dealt with the way we want to.

We will be using galleries linking to large size images and displaying them in a fancybox.

Magento & WordPress Multisite: a challenging marriage

For the relaunch of a project’s website, we chose to use two CMSes: Magento for managing products and being able to actually sell products online and WordPress for good old content such as news around products and company, information about the products’ designers and other similar stuff. But we were also having “satellite sites” / microsites around specific products or brands that were managed in different content management systems on different servers. This made publishing content to those different websites challenging and confusing for the editors as well as maintaining the sites for me as developer.

Content snippet in blog posts with a shortcode

You’re having the same content snippet on multiple WordPress blog posts and are fed up with making changes to that small piece on each single post? I’m showing you how to create a custom WordPress shortcode that pulls the content from a single post and injects it right into your blog posts.

Different database connections in WordPress development environments

Since I am using version control with GIT, I have set up different environments for my current WordPress/Magento-married project. For this project, I did not want to continue “cowboy coding”, so I set up a remote staging / testing / development site and multiple local development sites. Each site has its own purpose and needs its own MySQL database. So I had to handle different database connections in my WordPress installations. Well, I could work with only one DB,

Using the first image in a WordPress post as featured image

I am a hobby photographer and I like to show and share my “work”. WordPress introduced the “featured image”-feature in version 2.9 (as “post thumbnail“) which is fine for displaying an image that is somehow hooked to an article or blog post, or even a page.

Post Thumbnail, now Featured Image, is an image that is chosen as the representative image for Posts, Pages or Custom Post Types. The display of this image is up to the theme.

Hide a single category in WordPress

Recently, I was skimming through the WordPress Plugin Directory. I was looking for a plugin to hide a single category in WordPress, but doesn’t hide its posts. That plugin should only the category from the category listing beneath the (single) post and the sidebar. The reason is: I want to create an additional category that is listed nowhere in the frontend, but is still accessible from the category-archive page. Got that? 😉 No?

Adding a link to a WordPress image caption

In many blog posts of mine, I am using images and sometimes I even publish posts whose only content is an image. I have been asked by other bloggers, how I add a link to another site within WordPress’ native image-caption. Especially using the WordPress.com network, there doesn’t seem to be an easy way to use a link in an image caption. Though, the riddle’s solution is fairly easy, though.

Sometimes,
