Add the header information in top of your Plugin’s main PHP file because WordPress recognize to getting the information for Plugin management screen so it can be activated and run its functions. Below is the plugin header format:
1 2 3 4 5 6 7 8 9 10 11 12 | <?php /** * Plugin Name: Your Plugin Name * Plugin URI: http://Plugin_URL * Description: A brief description about your Plugin. * Version: Plugin's Version Number, e.g.: 1.0 * Author: Plugin Author Name * Author URI: http://The_URL_Of_The_Plugin_Author * License: A "Slug" license name e.g. GPL2 */ ?> |
