PHP and Ajax Asynchronous File Upload using jQuery


PHP Asynchronous File Upload

This tutorial is for beginners, who started working on PHP Project, and wants to add asynchronous file upload feature, so you’re at right place.

Detail Description:

So you might thinking what is file upload? And how it works?

The answer is here, to upload your file from your local machine to the server (website) is called file upload, it works exactly same as the definition, when we select our file from the browser and click submit, the browser takes file from our local machine and submits it to the server and server do his job to save the file to the defined path.

Here I am going to explain step by step process to create the file upload feature along with the source code of this tutorial so that you can easily download and test on your local machine.

The things you should know before following this tutorial:

  1. PHP
  2. HTML
  3. jQuery
  4. CSS
  5. Bootstrap

So let’s start some coding:

Look at the below code, from index.html file:


Form and Input Field: The basic need to upload file is to have <form> with enctype="multipart/form-data", if you notice the above file I have added form with enctype, next is the input field of file type, we have this field with the ID “file_to_upload“.

Submit Button: After </form> we have Submit button included with onClick event along with function call uploadFile(), we are going to write this function under script.js file, which is going to handle file upload operation.

Create script.js file:

Let’s create script.js file and add following source code in to it:


So we have our script.js file ready, here we have uploadFile() function is defined, this function is basically to check validation and get the selected file from input field and submit it to the uploadFile.php page asynchronously using ajax.

So now we need to create uploadFile.php, so go ahead and crated this file to the root, and use following source code:


Just a 10 lines code πŸ™‚ yes this lines is to have our file uploaded to the files folder on server, we are using move_uploaded_file() function here. if you remember we had send selected file from “file_to_upload” input field.

We are done with the code, find out following tutorial folder structure and complete source code below:
