How to Build a WordPress Plugin from Scratch: A Practical Developer Guide

A WordPress plugin can begin as one PHP file. This guide builds a small “Site Notice” plugin that lets an administrator save a message and display it above the site content. It is intentionally simple, but it uses the same building blocks as larger plugins: a plugin header, hooks, options, sanitization, escaping, nonces, capabilities, and conditional asset loading.

OpenAI Agents SDK Tutorial: Build Your First Tool-Using Agent

This OpenAI Agents SDK tutorial builds one small Python agent that answers inventory questions by calling a custom tool. The example is intentionally narrow: it looks up stock for a known product from local application data. That makes the tool-calling lifecycle easy to inspect before you connect an agent to a database, API, WordPress site, or WooCommerce store.

WordPress WP-Cron Not Working? How to Diagnose and Fix Scheduled Tasks

If WordPress scheduled posts, backups, emails, imports, or plugin jobs are late, start with four checks: inspect the overdue event, confirm that DISABLE_WP_CRON is not blocking processing, review Site Health and server logs for request failures, and determine whether the event’s callback is failing. These checks separate a general WP-Cron problem from one broken plugin task.

How to Automate WooCommerce Abandoned Cart Follow-Ups with n8n

You can automate WooCommerce abandoned-cart follow-ups with n8n by sending cart activity into a workflow, waiting for a defined period, checking whether checkout became an order, and sending a permitted reminder only when it did not. The important reliability controls are a stable cart identifier, an order-status recheck immediately before each message, suppression rules, and a stored sent status.

Laravel 13 Queues: Setup, Workers, Retries, and Practical Job Examples

Laravel queues move slow or non-essential work out of the web request. A typical flow is: your controller dispatches a job, Laravel stores it in the configured queue connection, and a worker runs the job separately. This guide uses a database queue as the shortest working path, then shows the Redis alternative.
