How to Show the File Name in a Bootstrap Modal Upload Form using JavaScript

When creating web applications with forms, user interaction is key. One common feature that enhances user experience is the ability to see the name of a file once it's selected for upload. If you're working on a Laravel-based application with a Bootstrap modal for file uploads, you might encounter challenges displaying the file name dynamically. In this guide, we'll walk through a practical solution to ensure users can see which file they have chosen to upload.

The Problem

You have a modal in your web application designed to handle file uploads. However, the JavaScript code you implemented to display the selected file name is not functioning as intended. Users are able to select files, but the name of the file does not appear in the input area, leaving them unsure of their selection.

Your Current HTML Structure

While this code appears correct, it didn’t yield the expected results. So, let’s explore the corrected approach.

The Solution

To correctly show the file name when a user selects a file, you can make a few adjustments to your JavaScript code. Below are two effective methods to achieve this.

Method 1: Refined JavaScript Event Handler

Instead of relying on document.getElementById, use the event target directly to access the files. Here’s the revised JavaScript code:

Testing Your Implementation

Once you've made these changes, test your modal by uploading a file. You should see the file name appearing in the label, enhancing the user experience by providing clear feedback of their selection.

Conclusion

Implementing a dynamic file name display within a Bootstrap modal can significantly improve the user experience of your web application. By utilizing the JavaScript methods outlined here, you can provide real-time feedback to users about the files they choose to upload. Whether you opt for a streamlined event listener or the onchange attribute, ensure that your final implementation aligns with your project's goals.

Now that you have a working solution, let's make the upload process more user-friendly in your Laravel application!
