How to Work with WordPress Plugins

First, understand how the primary system of WordPress works to create WordPress plugins. They are mostly software that uses hooks to communicate the codes. WordPress offers two types of hooks: behaviour and filters. These two elements are commonly used in plugin development. To know in detail, read below:


An action by WordPress refers to a particular event that will take place at a specific time. Through activities, the features of your plugin can be added or modified. When the action is activated, the functions attached to the action will be carried out. 

There are dozens of pre-defined behaviours of plugins that come with WordPress. You may use them according to your choice.


WordPress filters are hooks that accept a single variable or several variables and then return them after modification. In short, filters allow you to adjust the user content. The application filter function is used to build WordPress filters and specifies within that function. 

By using the filter hook application, you can create your filter. The add filter function can then be used to execute it. You can then add any specific function to the filter to control and return the variable.


With plugin development, you can put shortcodes that are user-oriented bits of code. It allows developers to build custom features for visitors to their pages quickly. The editor, menus, and widgets can place shortcodes in the posts and pages, etc. A variety of WordPress plugins use shortcodes. 

WordPress plugins are handy for internal links to old blogs. With the add shortcode feature, you can build your shortcode. The first variable is your short code’s name, and the second variable is the output function. Three values are used in the output function: attributes, content, and name.


The use of WordPress widgets allows the functionality of the device through an interface in WordPress. By expanding the WP Widget class, you can build a widget. It uses object-oriented widget architecture, ensuring that the functions and values are stored in the same class entity. 

You can efficiently structure your code and link to the API with the WordPress plugin. Then you can use some of the basics, such as scripts and styles, of the development of plugins. 

Finally, the building blocks are created for WordPress plugin development like custom content types and taxonomic, admin settings, HTML content performance, widgets, and shortcode creation. 

Know About Plugin Form

Dividing the plugin into many files and directories can be simpler if you construct complex functions, and this functionality is in WordPress plugins. You have to pick the desired plugin, and after some modification, your work becomes more manageable. 

You can put this in the main plugin file and add different files for other features if your plugin focuses on one main class. You can generate the normal CSS and JavaScript directories to store the necessary plugin file to improve the back end of WordPress with customisable controls.  

In general, the goal is to balance the structure, usability, and minimalism of the architecture. If possible, you can also split your plugin into several folders, but don’t go overboard. The WordPress plugin directory or the Envato Market has a great many plugins on sale. So, you don’t have to substitute the training to code for custom plugins if you’d like to take WordPress capabilities to the next stage.

Naming your Plugin and Features

There is caution in naming the functions, classes, and modules themselves when building a WordPress plugin. If you are using your plugin to produce significant excerpts, it might be reasonable to call it “excerpts.” But these names are much too common and overlap with other plugins with similar names. 

While using WordPress plugin Development, you must change the title. Using specific prefixes is the most common approach. You can, for example, use “acme excerpt” or something that is not likely to fit the naming scheme of anyone else.

Importance of Security Plugin

If you plan to distribute your plugin, then protection is essential because you now fiddle with other people’s websites, not just your own. All security actions you take are worthy of your product, so you should keep an eye on protecting your plugin. Only look at the principal in a nutshell for now; once you understand that, you should think about implementation.

The security of your plugin depends typically on its stability. The plugin does not assist in spreading ambiguous knowledge. This security includes filtering the input of the user, escaping queries to avoid SQL injections, etc. The second part ensures the consumer is empowered to perform a specific action. 

It essentially means that it should only be possible for users to remove data (such as administrators). The aim to protect visitors implies that a hacker has not deceived visitors.
