Customizing Forms with Radio Buttons in Symfony 6

Creating aesthetically pleasing and functional forms in web applications is crucial for enhancing user interaction. In this guide, we will explore how to customize a form with radio buttons using Symfony 6. If you're working with Symfony and want to improve your forms, this guide is for you!

The Problem

You've designed a form in Symfony, and now you want to incorporate radio buttons to give users an option that is both user-friendly and visually appealing. Radio buttons can be a great choice when you want users to select one option from a set. However, customizing these radio buttons to fit your needs might seem challenging. Let’s dive into how you can implement this effectively.

The Solution: Customizing Radio Buttons

To create a customized experience with your radio buttons in Symfony 6, we will follow these steps:

Step 1: Start with a Form Structure

Begin by setting up your form structure. You'll typically have an array of categories or options that will populate your radio buttons. Here is an example of how the initial setup might look:

However, to implement the customized behavior, we need some modifications.

Step 2: Modify the Form Widget

To ensure that clicking on a radio button triggers a specific function (like fetching related brands), we will modify the form widget rendering as follows:

Explanation of Code Changes

Adding an onclick Attribute:

The onclick event is added to each form_widget(child), now calling the getMarques JavaScript function with the value of the selected radio button. This enhances user experience by dynamically updating relevant content based on the selected option.

Custom Labels:

The custom <label> tags ensure that the radio buttons have an appealing visual style. The span within the label can be styled accordingly to highlight the selection.

Step 3: Styling Your Radio Buttons

To make your radio buttons more visually striking and user-friendly, add some CSS styles. Here’s a simple example:

This CSS will give your radio buttons a modern and clean look, improving the user interface.

Conclusion

Customizing forms with radio buttons in Symfony 6 creates a better user experience and enhances form interaction. By implementing the modifications outlined above, you can ensure that users find it easy to navigate through options in your applications.
