Here you can find the best and most useful code snippets for your WordPress website. I use this collection myself on BloggerPilot.
These small functions add helpful features to your blog, or disable unwanted WordPress features. Compared to plugins, code snippets put less load on your installation. To manage my codes I use the plugin Code Snippets Pro.
In these blog posts, we’ll cover what WordPress code snippets are, how they can help you, and how you can use them on your site. We’ll also share some popular code snippets that can be used to disable comments, add a custom login logo, and create your own 404 error page.
Code snippet is a programming term for a small area of reusable source code, machine code, or text. Usually, they are formally defined operational units that are incorporated into larger programming modules. Snippet management is a feature of some text editors, program source code editors, IDEs, and related software. It allows the user to avoid repetitive input during routine editing operations.
Code Snippet Definition
In programming practice, "snippet" in the strict sense refers to a portion of source code that is literally inserted into a file by an editor program, and is a form of copy-and-paste programming. This concrete insertion contrasts with abstraction methods such as functions or macros, which represent an abstraction within the language. Snippets are therefore primarily used when these abstractions are not available or not desired, such as in languages that lack abstraction, or for reasons of clarity and lack of overhead.
Snippets are comparable to static preprocessing in the editor and do not require compiler support. On the other hand, this means that snippets cannot always be changed afterwards and are thus prone to all the problems of copy-and-paste programming. That's why snippets are primarily used for simple sections of code (with little logic) or for boilerplate such as copyright notices, function prototypes, general control structures, or standard library imports.
If you want to improve your WordPress website, using code snippets is a great way to do it. Code snippets can help add new features, customize existing ones, and generally make your site more user-friendly and efficient.
While there are many different ways to use code snippets on your WordPress site, the most important thing is to make sure you implement them properly. That means adding them to the right files and testing them thoroughly before you make any changes to your site live.
Basically, code snippets are used for WordPress to perform certain actions that would otherwise require a separate, smaller plugin. Moreover, such code snippets are placed in one of the WordPress core or theme files. Namely, in the functions.php file of your child theme.
There are two ways to add code snippets to your WordPress website: by adding them directly to your theme's functions.php file, or by using a plugin like Code Snippets.
