Plug-Ins in WordPress

Plug-Ins – Plug what?

In the WordPress application framework, plug ins are a very cool addition.  Plug-ins can help you deploy
a full-blown web application with little to no knowledge of actual code.  The definition of a plug-in provided in the WordPress codex is,

“a program, or a set of one or more functions, written in the PHP scripting language, that adds a specific set of features or services to the WordPress weblog, which can be seamlessly integrated with the weblog using access points and methods provided by the WordPress Plug-in Application Program Interface (API).”

Plug ins allow you to turn your site into anything you can think of, from a basic blog to an e-commerce site to a social
There are a couple of plug-ins that come standard with any new WordPress install:  Hello Dolly and Akismet.  If you didn’t know, the Hello Dolly plugin adds a random lyric from
the song “Hello Dolly” by Louis Armstrong to the top of your dashboard on each page load. It’s not useful, but is a good way to see how to structure your own plug ins.

The Akismet plug-in integrates with to automatically filter out spam comments from your blog. While Hello Dolly is useless outside of its educational value, Akismet is downright necessary on any site with commenting turned on.
You always have the ability to deactivate these plug-ins or delete them altogether if you do not see any use for them on your site.
There are over 26,000 plug-ins available that can be accessed through the official Word‐Press plug-in repository. Not all plug-ins can be found in the repository, so you can always do a search on the Internet for whatever functionality you are looking for. Many plug-in
creators have their work available for download through their personal or business sites and many of these are available for a fee. There are also premium plug-ins, which are supported and that you have to pay to use.
