Hello friends, I want to know about wordpress plugin. I don't know about that and its working principle. Would you please help me for giving right definition and explanation about plugin?
From: (http: / /) codex.wordpress.org/Glossary#Plugin (I can't add links yet I'm too new) 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. Hope this helps!
