Frequently Asked Questions

Common questions about Series

Originally, it was a bit of a proof-of-concept of how plugins could create custom taxonomies based off a couple of highly-popular WordPress tutorials I wrote (Custom taxonomies in WordPress 2.8 and Using custom taxonomies to create a movie database). However, it was also a plugin I wanted for my personal blog. I'd been using custom fields for years to handle series, but it was always kind of a crude method of doing so. When WordPress created the Taxonomy API, I knew it was time to build something simple and usable for handling series on my site.

It creates a new taxonomy called "series" for use on your site. It gives you template tags, shortcodes, and widgets to allow you to more easily tie posts together in a series. Basically, you get a new meta box on the edit post screen titled "Series" that works just like regular tags. You can input a series name to add a post to a series. You also get a "Series" screen under the "Posts" menu in the WordPress admin.

You just need to set up the plugin. Go to Settings > Series in your WordPress admin and save the settings. It'll let WordPress know about your series permalink, which is necessary for showing series on the front end of the site.

Series - List Posts - This widget allows you to list posts from any series you've created. Series - List Related - This widget displays posts within the current post's series. So, it only shows up under two conditions: 1) you're viewing a single post and 2) the current post is within a series.

All standard WordPress functions for taxonomies work. The name of the taxonomy is series. So, if you want to do anything custom, WordPress already has the functions you need. I'm not going to list them all here. That'd be just like rewriting a large portion of the WordPress Codex, which is already available to you. If you're looking for a specific template tag, start with the category template tags. Most of them allow you to use custom taxonomies.

Okay. I'll show a few, but you've probably seen them before if you've done anything with tags or categories. Displaying a "tag" cloud 'series' ) ); ?> Displaying the current post's series Displaying a "category" list of series 'series', 'title_li' => false ) ); ?>

Certainly. You can create templates for series archives. Just copy your theme's archive.php or index.php template. Then, rename it to taxonomy-series.php and make custom modifications from there. If you want a template for a specific series, name the template taxonomy-series-exampleslug.php.

I'll consider it. Let me know what features you'd like to see added to the plugin. This is way too complicated for me! Please let me know how I could make things simpler for you in a future version of the plugin. Also, keep in mind that there are other series plugins out there. This particular plugin might not be the best fit for you. However, I'm more than willing to listen to feedback on making things easier.
