Category: Bug Fixing

A client’s plugin had a 200-line constructor stuffed with add_action and add_filter calls, so the class could not be tested or reused. Keep hooks out of the constructor.

A WooCommerce store’s coupons applied at random because functions kept overwriting shared globals. Wrapping the logic in a class with private data and public methods fixed it.

A walk through using a WordPress abstract class as a shared blueprint for plugin admin pages, so adding a new option means editing one child class instead of six copy-pasted files.

A client’s site was slow and under constant brute-force attacks on xmlrpc.php. The fix wasn’t blocking IPs but understanding WordPress entry points and closing the unused ones.

A client’s analytics plugin was one giant static class. Why overusing the WordPress static keyword breaks down, and how refactoring to a stateful object fixed it.

A WooCommerce thank-you message kept breaking because of a fragile concatenated string. Here’s how sprintf cleans up PHP string formatting and handles missing data.

Syncing users between two WordPress sites, I built a small REST API client on WordPress’s own WP_Http class instead of pulling in Guzzle. It uses dependency injection and returns WP_Error on failure.
