WordPress Plugins

~

I’m a programmer who uses WordPress. WordPress is so open and flexible that I cannot resist using my craft to tinker.

Plugins

Outreach Mission (in development): Outreach is not just software, it is a mission consisting of <is:thing>, <is:concept>, <is:word>, <is:product>, <is:place>, <is:person>, <is:corp>, <is:search> and <is:uri>. It’s that simple!
Zeitgeist (published at WPPlugins.org): A faster, more relevant, more flexible replacement for Dashboard. No matter how much or how little of interest is happening on your blog, see it all and reach it all, now! Super-fast, no RSS feeds!
Post Access Control (“Starred Passwords”) (in beta): Control which signed-in users can view posts, using a simple pattern in the password.
Performance Probe (in beta): Gather performance monitoring information from WordPress. Caution: highly technical and requires a small change to the WP core source code, so use at your own risk.

Widgets

You need to download and install the Widgets plugin for WordPress to use these.

Drop-down Archives (publshed at WPPlugins.org): A simple drop-down list of your blog archives and a “Go” button. Configure the widget to list the daily and/or monthly archives, how many of each and whether to show post counts. Shows the currently selected archive, if any.

Playthings

Abbreviate Site Title (for sharing): For all pages except the homepage, abbreviate the site title in the browser titlebar. For example, “Some Hot Italian Things” becomes…
Respectful Welcome (for sharing): Change the site description in the blog header to welcome the visitor by name, if known.
Use Request Host (for sharing): If you make test WordPress sites locally, this is really handy. When active, all site URLs generated by WordPress point to the host requested by the client instead of the host specified in the options. For example, a blog with URL http://localhost/~paul/blog/ will also work as http://pauls-linux-box/~paul/blog/.
Superceded by setting WP address to be root-relative.
Full Text Search (for sharing): A simple full-text search facility, accessed using ?fts=+this -that "and the other".
“Smiley” Performance Monitor (for sharing): How happy is this plugin with the performance of your WordPress blog? , , or ?
Page Permalinks End With “.html” (for sharing): Smartie on #wordpress asked and received. Does exactly what it says.
Inclusive Category Listing (for sharing): Ebow on #wordpress asked and received. Provides a wrapper function around wp_list_cats() with an “include only these category IDs” facility.

Full-Text Search

To avoid grinding your database server into the ground, add a full-text index to the post_content column of your WordPress posts table. For example, CREATE FULLTEXT INDEX content_fulltext ON wp_posts(post_content).

“Smiley” Performance Monitor

If WordPress appears to be slow or is grinding your server to the ground, activate this plugin to see how happy it is with the time and database effort required to make each page.

The first smiley indicates how many database queries; up to 30, then up to 100, up to 300 and over that.
The second smiley indicates how much time the page took to make; up to 1 second, up to 5 seconds, up to 15 seconds and over that.
Hover the cursor over either smiley to see the actual numbers.

Inclusive Category Listing

Ever wished you could call wp_list_cats() with “include” instead of “exclude”. Well, now you can, almost. This plugin provides a wrapper function for wp_list_cats() that takes a list of category IDs to include in the listing.

Update: by request, this now also works with the wp-leftycats plugin.

Download this plugin at WPPlugins.org.
