  • What Can the 4WP Drive Plugin Do for You?

    What Can the 4WP Drive Plugin Do? 4WP Drive is a WordPress plugin that removes manual copy-pasting between Google Docs (or GitHub) and your site. A writer drafts in a familiar editor, an editor reviews it in a built-in Inbox, and once approved, the material becomes a draft post — no copy-paste, no lost formatting.…

  • SOLID in the WordPress Ecosystem: What 4wp.dev’s Plugins Actually Prove

    WordPress makes it easy to write code that works and easy to write code that lasts, and those are not the same skill. Hooks, filters, custom post types, widgets — the platform hands you enough rope to build something maintainable or something that collapses the moment a second developer touches it. SOLID is the discipline…

  • muplugins_loaded: The Hook That Actually Fires First in WordPress Slug: muplugins-loaded-the-real-first-hook

    Quick interview trap: which WordPress hook fires first? Ask ten WordPress developers “which hook runs first?” and nine will say init. The sharper ones say plugins_loaded. Almost nobody says muplugins_loaded — and that’s exactly why interviewers who know their stuff love asking it. muplugins_loaded fires the instant WordPress finishes loading must-use plugins (and, on multisite, network-activated plugins)…

  • 4WP Smart Link: How a Common Client Request Became a Scalable Open-Source WordPress Plugin

    Let’s use a real case — a routine client request to make a Cover block’s photo clickable in FSE Gutenberg — to walk through what client-centricity, thoughtful design, and scalability actually look like in WordPress development. Let’s dive into WordPress development — domain first, integration second. There can be plenty of ideas for a new…

  • 3 WordPress Hooks Every Developer Should Know: Classic vs Block Theme

    These three hooks fire on every single WordPress site, no matter what theme is running underneath. The hook itself never changes. What changes — quietly, and in ways most tutorials never mention — is how it gets called. If you learned WordPress on a classic theme, you know the drill: wp_head() and wp_footer() get called…

  • 4WP-Booking: How One Dental Clinic’s Request Became a Domain-Driven WordPress Booking Platform

    Most WordPress booking plugins start the same way: a client needs to connect their site to a specific tool, so a developer wires up that one API and ships it. It works — until the second client shows up with a different calendar system, and the “quick integration” has to be rebuilt from scratch.

  • The WordPress Developer Market Has Quietly Split in Two

    We track WordPress developer job postings daily — not to republish them, but to dissect them. Every listing that comes in gets broken down into skills, requirements, and the real signal buried under recruiter boilerplate. Here’s what a live read of current postings shows. What the Data Shows Across the WordPress developer roles currently open,…

  • What Can the 4WP Advanced Code Plugin Do for You?

    4WP Advanced Code extends WordPress’s native code block instead of replacing it. It adds syntax highlighting, a copy-to-clipboard button, deep-linking anchors, and SEO-friendly structured data — all without forcing you to re-enter your existing content. Key capabilities Pain points it solves Who it’s for Developer blogs, technical documentation sites, plugin and theme developer portals, and…

  • Webhooks in WordPress for Bidirectional CRM Integration: Incoming, Outgoing, and Async Processing

    1. Overview Webhooks enable automated communication between WordPress (WooCommerce) and an external CRM system when specific events occur. The objective is reliable order synchronization without blocking execution, losing events, or introducing unnecessary architectural complexity. In a typical integration: 2.
