How to Display a Hidden HTML Div Using PHP and JavaScript After Form Submission

When developing web applications, it’s common to encounter challenges that require interaction between front-end and back-end technologies. One such problem that many developers face is getting a JavaScript function to display a hidden HTML element after a form submission using PHP. If you find yourself grappling with this issue, you’re not alone, and this guide is here to guide you through a clear solution.

The Problem

The key areas of concern are:

Form submission: How should the action of the form be set?

JavaScript functionality: How can you effectively change the display property of your div based on the form submission?

Understanding the Solution
