Mastering WordPress Form Field Validation Using Database Data

Take your #WordPress forms to the next level with Helen! In this video, you’ll learn how to validate user input using live website data and apply advanced rules powered by your WordPress database.
Discover how to:
✅ Check user input against existing posts, users, or metadata.
✅ Use dynamic website data: purchase history, stock levels, or custom logic to validate submissions.
✅ Automatically populate emails or database entries with extra related info retrieved via JetEngine queries.
We’ll use #JetFormBuilder, #JetEngine, and the free JetEngine Query Action add-on to make forms smarter, faster, and more interactive.
Turn your forms into fully data-aware components that adapt to real conditions on your site.
