According to WordPress.org a plugin is: “… a group of php functions that can extend the functionality present in a standard WordPress weblog. These functions may all be defined in one php file, or maybe spread among more than one file. Usually, a plugin is a php file that can be uploaded to the “wp-content/plugins” directory on your webserver, where you have installed WordPress. Once you have uploaded the plugin file, you should be able to “turn it on” or Enable it from the “Plugins” page in the administration interface of your weblog. The WordPress source code contains hooks that can be used by plugins.” [As of Jan. 26, 2010 – source: http://codex.wordpress.org/Glossary
My translation of this is: A mini program whose code is already written for you that enhances the operation of your Web site or blog and/or allows you some degree of customization.
WordPress generally comes with two standard plugins. These are Akismet, a spam filter, and Hello Dolly, an application. You can search for plugins in the pull down section of your dashboard, get information, visit the author’s site and even see applications or get instructions. You can install plugins from the same area or screen once you determine what plugins are suitable for your site.
Caution: Use only plugins from reputable sources such as those listed under WordPress.org. If you are like me and not a coder, neither of us can tell if there is malicious code within the plugin’s code! Beware of charlatans and snake oil salespeople.
Most plugins are free although the authors sometimes request donations. I will add discussions of WordPress plugins I use and recommend below:
Better Delete Revisions
(Jan. 26, 2011) When you edit a post or a page in WordPress, the program automatically creates a backup file in your database. Therefore every time you add a revision you increase the size of the database. Multiple revisions add multiple saves and the older data keeps accumulating. This plugin removes and deletes old revision of posts, pages and related meta content completely. I have been using this plugin without incident for the past several months.
This plugin is listed on the wordpress.org site and you can learn more about it Better Delete Revision.
