What Programming Language for WordPress

Due to the fact that JavaScript runs on the computer of the user accessing the website, we refer to PHP as being “client-side” and consider it to be “server-side” since it operates on a remote server. The HTML document that uses CSS and JavaScript is created by PHP on your web server. The structure and content of a document are specified using HTML in the browser. JavaScript manipulates the HTML and the CSS that is applied to the document, which is styled using CSS to alter its visual look.

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.

Website Hooks

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.

Java Script Events

In JavaScript, we can “bind” to events that are brought about by a user action, like a click, or a change in the page, such the page fully loading. People frequently wish to alter what happens when a user clicks on something. In this instance, we must tie a JavaScript function to the selection of a certain HTML element. Using the jQuery JavaScript library makes this much easier than using JavaScript alone.

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.
