Log Events & Debug Custom Code with WooCommerce Logger

WooCommerce provides a simple way to log your custom events and debug your custom code and plugins. By using this built-in tool, you can easily track errors, troubleshoot issues, and log important actions, making debugging more efficient in WooCommerce development.

Hosted by Rodolfo Melogli

Session overview

In this webinar, we’ll dive into the WooCommerce Logger class (WC_Logger) and explore how it can be a game-changer for debugging and tracking custom events within your WooCommerce store. Whether you’re a developer building custom plugins, adding bespoke features, or troubleshooting code, WC_Logger provides a powerful yet easy-to-use tool to log everything you need.

When working with WooCommerce, debugging is a crucial part of the development process. Errors, unexpected behaviors, and performance issues are common, and without a robust logging mechanism, it can be difficult to pinpoint the cause of problems. The WC_Logger class allows developers to log detailed information about events and errors, making it easier to diagnose issues and improve the reliability of your store.

When you build custom functionality in WooCommerce—whether it’s a new payment gateway, shipping method, or custom admin tools—you often need to monitor the behavior of that code. WC_Logger allows you to log events that are important to your development process. You’ll learn how to write these custom log entries, store them, and retrieve them for analysis.

Throughout the session, we’ll demonstrate live examples of how to log events in WooCommerce. You’ll see how easy it is to implement logging within your custom code and how the logs appear in the WooCommerce admin interface, giving you direct access to important debugging data. Whether you’re working on a small custom feature or a large-scale project, you’ll walk away from this webinar with a deeper understanding of how to leverage the WooCommerce Logger class to improve your workflow and troubleshooting process.

So, join me for this hands-on, live session where we’ll unlock the full potential of custom logs. Don’t miss the opportunity to learn from my real-world examples – as well as the chance to learn and connect with the Business Bloomer Club WooCommerce community in real time!
