Woocommerce helper functions

Trusted by In the first part of this series , we learned the key concepts to build an application that is as CMS-agnostic as possible. In this second and final part, we will proceed to abstract a WordPress application, making its code ready to be used with Symfony components , Laravel framework , and October CMS which is based on Laravel. Before we start abstracting the code, we need to provide the layer of dependency injection to the application. Note: For ease of reading, I have omitted adding namespaces to all classes and interfaces throughout this article. Instead, we must access the function from a contract an interface , on which the CMS function will simply be the implementation.

Privacy Policy Helper

The codebase of a project is in continuous evolution. We add new features, fix issues, and at some point in the development, we found that some code we wrote in the past is no longer necessary.

Under this situation, we may have the temptation of removing this piece of code, but is it right? Well, it depends. By contrast, if we are developing a product that is used by many users in different ways and environments, then we have to be very careful with the changes we include and the code we remove. Otherwise, we might break things. This aspect is especially important in WordPress, where the combinations of plugins, themes, and server configurations are practically infinite.

Besides, we have to consider the possibility that the user has included customizations for your product thanks to the extensibility of WordPress with the usage of hooks. If we are working on a WordPress plugin, theme, or a WooCommerce extension, we cannot just remove the obsolete code, we need to deprecate it. Optionally, you can provide an alternative, if exists. We can see some interesting aspects of this function.

We know when it was introduced version 1. One important thing to take into consideration when deprecating a function, and any code in general, is to keep the behavior untouched.

That means the function, although deprecated, must go on doing the same task than before if possible. First of all, we have added the tag deprecated in the documentation of the function. This is the proper way to document when this function was deprecated. This feature is really helpful while you are writing code because you can see clearly that something is wrong with this function.

Great, now we have our log full of warnings for using a deprecated function. How can I fix that? The answer is simple, stop using this function. We need to know we are calling to a deprecated function and where. The first parameter is to indicate what function is deprecated. Finally, the deprecated function calls to the new function to accomplish its functionality.

Remember the function should continue working like before. When we want to deprecate an argument of a function or method, the process is slightly different. Obviously, we cannot use it because the function is still valid. We are deprecating one of its arguments only. Instead, we add another since tag to the documentation of the function. This is a good practice.

Every time we introduce important changes to the behavior of a function or method, we should add a since tag to log when these changes were introduced. For example, in PHPStorm you can preview the name of the arguments when calling a function. For the third change, we have set the default value of the second argument to null.

This way, we can remove it from the calls to this function. Another WordPress function to help us to deprecate code. Note: If we would like to deprecate the first parameter, the process would be the same.

Required parameters after optional parameters are not allowed in PHP 8 or higher. A different situation is when we want to modify the accepted values for an argument. Suppose we have an argument that used to accept a string and an array as value. Now, we want to accept an array only. So, we can do the following:. The best way to learn how to do it is with an example:. That means developers can do things like that:.

If we want to remove this property or change its visibility to protected. We have to keep the backward compatibility with this property. Here is how to proceed:. There are a lot of things to explain here. Additionally, we have to return the expected value for this parameter in order to keep the backward compatibility. Hooks filters and actions is an essential part of the WordPress core and is what makes it so extensible and customizable.

When we develop a WordPress plugin or theme, we can add custom filters and actions to allow other developers to modify the behavior of our product or expand it with new features. We need to make our best to keep the backward compatibility with our hooks every time we modify or remove them. Have you said to remove them? Yes, but this should happen in future releases, before that, we need to deprecate them.

In our example, we have an action hook that is triggered at some point in our code. The code for deprecating things starts being familiar to us. Thanks to this function included in the WordPress core, we can know if there is any callback registered for this action hook, and in case of true, we execute our deprecated action to keep backward compatibility.

An action is nothing more than a filter that returns void ,. Finally, I would like to make a special mention of some helper functions included in the WooCommerce core that are really useful when we are working with this e-commerce plugin. But what makes them so interesting?

Well, if you take a look at their code, you will see that they are wrappers of the functions we have seen in this post, but changing their behavior when they are called during an AJAX or a REST API request. In these kinds of requests, the deprecation warning is logged but not triggered. By doing this, we avoid breaking the returned result. Good point for the WooCommerce team! If you are developing a WooCommerce extension, I encourage you to use these functions.

If not, you can still create similar functions in your project. Dealing with obsolete code is part of our work as developers, and in this post, we have learnt some techniques to deprecate these pieces of code before removing them from our project definitely. When to remove this legacy code and where to locate it meanwhile will be discussed in another post, this one is already long enough.

Thanks to the code deprecation, we can make our project grows at the same time we keep backward compatibility with older versions.

Additionally, we create a smooth transition and give enough time to other developers to migrate and adapt their WordPress sites to the new changes.

Definitely, this is a vital aspect when we are creating a product that will be used by thousands of customers around the world. Because nobody wants a product that breaks things with each update. Close Menu Home. LinkedIn GitHub. To summarize: If we are working on a WordPress plugin, theme, or a WooCommerce extension, we cannot just remove the obsolete code, we need to deprecate it.
