Why WordPress plugins?

This is very important to understand why WP plugins are awesome and why you should add your custom or additional features and functionality in WordPress plugin and not in your WordPress Themes. The answer is simple; first – it’s a modular approach that makes new features and functionality plugable to your WordPress website, which saves development cost and maintenance cost too and secondly – plugins don’t have to do anything with WordPress theme development; your theme remains untouched and this modular and plugable approach lets you change your WordPress theme easily without a need of a developer.

Manually Create WP Plugin

To create WordPress plugin manually, we need to create a new folder with your plugin name, without any space between words, replace spaces with dashes, and create a php file with the plugin folder name, and define your plugin meta data like below.

 * Plugin Name:     Service Page Links
 * Plugin URI:
 * Description:     This plugin creates dynamic links
 * Author:          Amulya Shahi
 * Author URI:
 * Text Domain:     Service Page Links
 * Domain Path:     /languages
 * Version:         0.1.0
 * @package         Service_Page_Links

Enqueuing Styles and JavaScripts in WP Plugin

To enqueue styles and javascript, we use the default style and script enqueue methods that are used in functions.php file for a theme. Except we use plugin_url() method and __FILE__ as an argument to this method, like below.

function enqueue_service_page_links(){
        wp_enqueue_style('related-styles', plugins_url('links-style.css', __FILE__));
        wp_enqueue_script('related-script', plugins_url( 'links-script.js' , __FILE__ ), array(), true, 200);
