How to Show a Hidden Div After Clicking a Submit Button in PHP

Have you ever wanted to reveal a hidden section on your webpage after a user interacts with a form? If you’re working with PHP and JavaScript, this can be accomplished with great ease. In this guide, we'll address a common issue: How to show a hidden div after clicking a submit button on a different PHP file.

The Problem

In your PHP application, you may have a hidden div that you would like to display once the user submits a form. For instance, let's say you have a form that accepts a YouTube video URL. Upon successful submission, you may want to show a result to the user—all without the need for a page refresh.

Here’s a quick recap of what you have:

A hidden div (<div id="ScoreResult">) that you want to display.

A form where users submit data to an endpoint.

Some JavaScript functions that control the visibility of the div.

The Solution

To achieve our goal, we need to break down the solution into structured steps:

1. Setting Up Your PHP Files

This file processes the form submission and determines if the conditions are met to display the hidden div. Here's what to include:

This file contains your form and the hidden div. Notice how the div will only be displayed if the $verified_success variable is set.

2. Form Submission and Validation

If conditions are met, set a variable that indicates successful verification. This will help in determining whether to display the hidden div.

3. Displaying the Hidden Div

Once validated, the hidden div (initially styled with display:none;) is modified to display using PHP logic. If $verified_success is set to 'yes', then the div will appear on the page.

Conclusion

In this step-by-step guide, we explored how to make a hidden div visible in a PHP application upon form submission. This approach enhances user experience by providing immediate feedback without page reloads. You can further adjust styles, add animations, or include more complex validation as per your requirements.

With these insights, you're now equipped to create dynamic, interactive web experiences using PHP and JavaScript! Happy coding!
