This plugin gives content developers shortcode equivalents to the conditional tags that WordPress provides for theme developments. Each shortcode only includes its contents if a certain condition is true. This allows them to modify what content is shown in any given context on a post-by-post basis.

The new shortcodes and when they include contents are:

• is_single - if showing a single post.
• is_singular - if showing a single post or page.
• is_home - if showing the blog home.
• is_front_page - if showing the front page of the site.
• is_sticky - if the current post or page is 'sticky'.
• is_category - if showing a category-based archive.
• is_tag - if showing a tag-based archive.
• is_tax - if showing a tag- or category-based archive.
• is_author - if showing an author-based archive.
• is_archive - if showing any archive.
• is_year - if showing a yearly archive.
• is_month - if showing a monthly archive.
• is_day - if showing a daily archive.
• is_time - if showing an hourly or shorter archive.
• is_feed - if generating a feed.
• is_search - if showing search results.
• comments_open - if comments are open for the current post or page.

Each shortcode also allows has an "else" shortcode that can go inside it. For example:

[is_single]
This is only shown if showing just this post.
[not_single]
This is shown everywhere else.
[/is_single]

In general, the "else" shortcode is just replacing "is" with "not". The one exception is "not_comments_open" as the "else" shortcode for "comments_open".

Whichever chunk of content is included is processed for shortcodes, so you can use all your other shortcodes and even nest these if you need to.
