The Problem

You have a component that allows users to upload multiple images, and you want to send each image as a separate request to your backend API. The catch? Your backend does not support multiple files in one field. Unfortunately, you may find that all your API calls are sending the same last image instead of each different file.

Key Issues

Single FormData Instance: If the FormData object is created outside of your loop, the last file gets reused for all requests.

Need for Multiple Requests: Since your backend enforces one file per request, it's essential to send each file individually.

The Solution

To resolve the issue of sending the last file repeatedly, you'll need to ensure that a new FormData instance is created within your loop. Here’s how to restructure your code for clarity and functionality.

Step-by-Step Implementation

Declare formData within the Loop: Ensure that you create a new instance of FormData inside your loop that iterates through the photos array. This way, every file gets its own separate FormData object.

Here’s the adjusted method code:

Handle File Uploads: Make sure that your file input properly gathers all selected files and stores them in the photos array.
