If you are creating an option creation, update, saving and redirection, then WordPress will handle all of these.
Let’s create a WordPress plugin with options page in the WordPress admin area. first, write the header of your plugin by using below code.
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 | < ?php /** * Your Plugin Name * * @package PluginPackage * @author Your Name * @copyright 2016 Your Name or Company Name * @license GPL-2.0+ * * @wordpress-plugin * Plugin Name: Plugin Name * Plugin URI: https://example.com/plugin-name * Description: Description of the plugin. * Version: 1.0.0 * Author: Your Name * Author URI: https://example.com * Text Domain: plugin-name * License: GPL-2.0+ * License URI: http://www.gnu.org/licenses/gpl-2.0.txt */ |
