To know what kind of code to look for, you must have a thorough understanding of what the four languages perform and where they are used. It will be simpler to determine what type of code has to be altered to accomplish a task once you are aware of the various tasks that each role has.
Events are what drive WordPress. That is to say, there are a number of events you may use to change or add to the functionality. WordPress uses a set of “hooks” on the server to enable you to change the value of something — we call these filters — or perform an action at a certain time.
Consider hooks as places where people can pause and are encouraged to take action. WordPress checks to see whether any additional functions are attached to the current filter or action before it reaches a hook, and if they are, it calls all of those functions before continuing.
If someone asks you to add some code, such as Google Analytics tracking code, to your page’s header, that is an example of employing a hook. The action “wp head” should be called by every WordPress theme before the closing HTML head tag. You can echo your analytics code in “wp head” by hooking into it.
Filters allow you to change a specific thing, whereas actions allow you to do something at a specific moment. Use the “the content” filter, for instance, if you wanted to include some more content, like details about a service or a link to a signup form. With the use of this filter, you can edit, replace, or add new content to any post that is being displayed.

What is the Best Way to Add Custom Code to WordPress?
In WordPress, there are three ways to show code. If you’re a novice who doesn’t frequently need to display code, you can utilize the Gutenberg editor. For a simpler procedure, you can also use a plugin. Or, you can manually convert your code into special characters known as HTML entities, which is advised for experienced users.
I’ll discuss how to add custom code to your WordPress site the following week. You should now be better equipped to analyze, test, and implement the code you require after reading this tutorial.
