The WordPress Content Management System (CMS) has transformed the face of Internet. It brought an array of new ideas to flourish along with its open source document, which holds sound prominence rooted in web and software development. It is typically a blogging platform that has the capability of launching in a number of scripts like job boards, and even the classic Web Page CMS. A striking feature of this platform is: with the help of custom wordpress development, users get the scope of personalizing any part of the website, thereby making the site to appear unique.
In this article, you will be able to discover a list of ways for getting started with plug-in development. These steps are quite simple, which do not require you to undergo an in-depth research. Basic knowledge on PHP is just required along with rudimentary understanding of the Administration panel and WordPress file structure.
Why use WordPress for Website Development
Plug-ins serve as the ideal way for enhancing functionality of the blog by adding a number of extra features. These elements may be placed inside the template with the help of function hooks. With time, adjustability of WordPress’s plugin system has allowed tremendous growth along with numerous developer-submitted software pieces.
Being the developer, you will be allowed to have complete control on all the backend details of the weblog. Thus, seeking assistance of a PHP developer in the process of creating a system plugin will be comparatively expensive and the API will be easy enough for working with and learning.
Adding to its benefits, developing the website over WordPress mostly prove to be the superior practice for tuning into various other areas. Creating smaller sidebar widgets and plugins in WordPress facilitates you to understand the entire working process of the backend system.
WP Folder Structure
An introduction to the WP Folder Structure will enable you to see all the basic app directories. Inside the WP content, there will be a plugin directory. All the individual plug-ins, including the specifically-named sub-directories and single files are being housed in this directory.
Starting the PHP file
While creating one new plugin, at first, you need to create a simple PHP file. The file can be given a generic name, however, it should be kept in mind that it should reflect the official name of the plugin.
First lines of the plug-in should deliver apt comment information of the parsing engine. It is extremely essential as WP will not be able to access the file without this kind of detailing. The Plugin name is shown in the Admin Backend panel at the time of activation. Although it is not needed to include a description or version, but, while concerning on value addition, it certainly makes the plugin to appear much more professional.
Best practices and WordPress Naming Conventions
There are certain ways for structuring the plugin. Often, PHP developers will develop an a complete class system to avoid any kind of collisions with the variable named and functions. If you are not much aware with PHP’s superior OOP functionality then, the ideal choice is to write the code in sample functions.
Thus, for the example code, you will require to write a single function for housing data. Additionally, you will also require to define certain variables, which serve as the key of implementing inside the template files.
Knowing More about Actions and Filters
Another important concept, which is noteworthy to mention before jumping into the raw code is: Filters and Actions. The functioning of these two elements are entirely different, which relate to the ways for manipulating plugin data.
These bits of code are noted inside the WordPress API. Actions and Filters allow the plug-in developers for updating bits of code within the entire WordPress admin panel relating to the new plugin.
Understanding Add Filter
A filter is generally used on a small bit of data or text, thereby being passed to the WP. While using filters, you will be able to filter content by the custom-written functions for changing data as per your choice.

Resultantly, these are considered as quite popular while writing the smaller functions or sidebar widgets as well.
Understanding Add Action
Actions are quite similar to the filters as because, similar to the later one, actions do not operate on bits. Rather, they target a list of predefined areas of the admin panel and templates, thereby allowing you to apply for an action at the time of editing or updating any page’s content. WordPress comes with a list of comprehensive actions in the API documentation.
Comprehending the actual difference in between filters and actions will ultimately lead you to build extensive, working WP plugins.
Completing the Plugin Logic
While finishing up the path, you need to add the final function precisely into the plugin file. Noticeably, API documentation is quite particular, thereby working as an excellent resource provider for developers, who might have certain advanced questions. The component can seem to be difficult, if the person is not so familiar with PHP and thus, in-depth understanding is required.
Above stated were the basics, which you need to go through for getting started with WordPress development. Additionally, with the help of custom wordpress development you will be able to customize the website as unique, thereby making it more appealing. The plugin system is quite vast, which comprises of great internal functionality. So, to make the most of WordPress, learn more about the basics of this concept and excel as a master.
