In this post i will give you code of sample plugin file. The sample plugin file should contain plugin header in which you put plugin name and plugin url atleast. You can put GNU license in it also.
The sample plugin file looks like this:-
<?php /* Plugin Name: My Plugin Plugin URI: http://example.com/wordpress-plugins/my-plugin Description: A brief description of my plugin Version: 1.0 Author: Your name Author URI: http://example.com License: GPLv2 */ /* Copyright YEAR PLUGIN_AUTHOR_NAME (email : PLUGIN AUTHOR EMAIL) This program is free software; you can redistribute it and/or modify it under the terms of the GNU General Public License as published by the Free Software Foundation; either version 2 of the License, or (at your option) any later version.
