How to use FormData for AJAX file upload? 💾📤

Have you ever needed to upload a file using AJAX, but didn't know how to handle it? This can be a common issue, especially when it comes to dynamically generated forms. But fear not! In this guide, we'll show you how to use FormData to successfully upload files using AJAX. 🙌

The Problem

Let's start by taking a look at your code. You have a dynamically generated form and you want to upload a file using AJAX. However, you're not sure how to handle the file input. Don't worry, we've got you covered! 😎

The Solution

To handle file uploads using AJAX, we can make use of the FormData object. FormData is a powerful feature that allows you to effortlessly send and retrieve data from a form, including files. 📁

In your JavaScript code, you'll need to make a few modifications to successfully upload the file. Let's break it down step by step:

1. Capture the form submission event using the .submit() function in jQuery:

$('.wpc_contact').submit(function(event){
   // Your code goes here
});

1. Get the form name and serialize the form data:

var formname = $('.wpc_contact').attr('name');
var form = $('.wpc_contact').serialize();

1. Create a new FormData object and pass in the form element:

var FormData = new FormData($('.wpc_contact')[0]);

1. Make an AJAX request with the FormData object:

$.ajax({
   url: 'your_upload_url',
   data: FormData,
   type: 'POST',
   processData: false,
   contentType: false,
   success: function(data){
      // Handle the success response
   }
});

That's it! By following these steps, you'll be able to upload files using AJAX with ease. 🎉
