Custom Wordpress Plugin Development

Nowadays, we hear a lot about custom WordPress plugin development. But do we understand the difference between a WordPress plugin and a WordPress theme properly?

WordPress plugin development serves more as a program or even a function that allows adding services and features to your current WordPress development platform.

Frequently Asked Questions

In WordPress, the functions.php file serves as a template predicted by WordPress themes. This file acts as a plugin for your WordPress website, and you can load it automatically when installing and activating a theme on the site.

Using PHP code, you can add a function to your plugin file or change the default features on your website. Thanks to editing the functions.php file by applying a custom plugin code, you can add post types, shortcodes, or taxonomies for improving your site.

A WordPress plugin is a PHP file that includes a WordPress plugin header comment. Thus, we highly recommend creating the plugin directory and folders (each plugin folder for a separate plugin) to hold all your WordPress plugins. That allows organizing all of the plugins’ PHP files in one place. If you want to build a new plugin, you can create a new folder and hold the necessary files here.

It relies on your project requirements. If a plugin partially fulfills your need and we should take simple steps and make some changes to satisfy your requirements completely, we recommend applying customization. But if your requirements mean adding new functions to current ones, it will be better to build a new plugin.

Action Hooks serve as an extremely useful tool in WordPress that developers apply for performing functions (actions) in different places of themes or plugins. Thus, lots of themes and plugins implement action hooks as an easy approach for users to modify the project’s output or provide their custom code.

With the ultimate WordPress auction plugin, the owner can set up auctions on his website easily and quickly. This plugin is simple, flexible, and very configurable. Also, it provides multiple features, along with great support.
