Sometimes a WordPress project calls for custom fields on Media. We recently built a custom gallery widget that involved uploading multiple images that would have a caption, a heading, the ability to selectively output the image, and the ability to set the hex code color of the text that was output.
To achieve this, I created a custom field on images that would allow you to input a value to be used as the color for the text and a custom checkbox to indicate to output the image.
There are two steps to this:
- Add the custom field to the edit screen,
- Process that field when saving / updating the media item.

We love developing in WordPress. For many of our clients, there is no need to reinvent the wheel and WordPress can be a significant time saver.
WordPress is a very thoroughly developed platform – yet every now and again we bump into desired functionality that isn’t readily available, such as excluding categories from the Archive Widget.
Recently, I developed some code to do just that and thought I would share it.

There are a lot of good membership plugins out there – we recently finished building a site for a client using WishList Member and ran into a problem when trying to determine if the logged-in user has access to a given piece of Pay-Per-Post content.
There are a couple of key features that made WL Member ideal for this project:
- It allows the purchase of content on either a per-post or subscription basis
- It blocks access to Private Media by using htaccess to route the requests through a PHP script
This project called for us to only output links to attachments if the logged-in user had access to the content, and to do so in list views after the Read More tag was output.

I’ve helped our clients set up a lot of membership sites; one common request is that members are able to submit articles within WordPress.
Out-of-the-box WordPress can get you pretty far but commonly I run into two roadblocks with the default roles:
- The Contributor role doesn’t let Contributors see the Media Library
- The Author role lets Authors see everyone’s Media & Posts
While more often than not a plugin is the way to go for a full-on membership site, there’s a really quick fix that will let you assign users to the Author role and be able to hide other’s Media & Posts from them.

I wanted to setup a simple lightbox photo gallery on a WordPress site (v3.2.1, tested and working on 3.3.1) and, to avoid installing a slew of plugins, I put together a little gallery shortcode function using the built-in WordPress gallery shortcode as my starting point. I’m a big fan of PrettyPhoto, so I modified the output of the gallery shortcode to include a rel= attribute for PrettyPhoto galleries. (more…)

I recently needed to output a list of comments and bumped into a little trouble trying to output the comment excerpt. Usually I would use the built-in comment_excerpt() function but I only needed 10 words instead of the 20 that is hard-coded. I put together a little function that I found helpful and thought I would share.
