In order to provide maximum flexibility, In Series formats posts based on a set of special formatting strings. These are accessed through the 'Series' sub-menu under the 'Options' menu in WordPress. You must have the 'manage_options' capability (WordPress 2.0 and later) or have at least user level 8 (prior to WordPress 2.0) to alter these options.
For the time being, the formats are site-wide, and appear on both single- and multi-post pages. This will change in the future, but for the time being, make sure that the formats you select look acceptable to you throughout your site.
The key component to all of these fields are a set of special tokens. These are replaced with appropriate values, based on context. The complete list of tokens is as follows:
It is important to note that the above tokens may expand differently (or not at all) if used inside of an HTML tag. A very common scenario that illustrates this would be %title. The first %title will have any HTML stripped out of it, and will have the remaining special characters (like "'" and "<") escaped. The second %title, though, will not have any content stripped or escaped. The special expansion rules apply as described in the list below:
Not expanded between < and >
HTML-stripped and escaped between < and >
Expanded the same everywhere
This option controls the manner in which each post is generated. It is important to have the "%content" token (without the quotes) appear exactly once in this field. More than once, and the post's contents will show up twice; if "%content" isn't present at all, then your posts will not have any content. In Series will not prevent you from making this mistake, so please double-check!
Valid tokens for this field are:
This option controls how the %next token is expanded.
Valid tokens for this field are:
This option controls how the %prev token is expanded.
Valid tokens for this field are:
This option controls how the %toc token is expanded.
Valid tokens for this field are:
These fields control how the %entries token is expanded. The entry link field is used for most of the entries. However, if the post that the %entry token would ultimately be a part of is the same post that an entry would refer to, the active entry link field is used instead. This allows you to prevent having a table of contents with a link pointing to the page that you're already on (for example).
These fields are present for both the table of contents, and the series list.
Valid tokens for these fields are:
As a special note, the series list is not automatically inserted. Currently, it can be accessed through a template tag only. The use of the series list is, therefore, unsupported for the time being.
Aside from the formatting strings, there are some other options that can be controlled from the 'Series' menu.
This option, when enabled, will insert and (with appropriate hrefs) in each single-view page that displays a post in a series. Some browsers can use this information to more explicitly understand that the page is part of a series, and is intended to improve accessibility.
In Series tries to make it as easy as possible for authors to create and change series. Series manipulation is handled with post editing; to change a post's relationship with a series, start by editing the post.
Note that deleting a post will automatically remove it from any series that it is in.
