How to Upload File & Image in CodeIgniter Ajax With Source Code

Upload File CodeIgniter Ajax is the process of sending a file from one computer system to another, usually a larger computer system.

From the point of view of a network user, uploading a file means sending it to a computer that is set up to receive it.

About the Project

Upload File was developed using CodeIgniter, Ajax, and MySQL Database as Back-End. Most web applications require file management.

If you’re creating a content management system, you’ll need to be able to upload photos, word documents, and PDF reports, among other things.

If you’re creating a membership site, you may need to include a feature that allows users to upload their profile pictures. All of the following is made simple with CodeIgniter’s File Uploading class.

In File Upload With CodeIgniter, there are two stages to file uploading. There are two parts to a website: the frontend and the backend.

The HTML form that employs the form input type file handles the frontend.

The File Upload In CodeIgniter With Example processes the form’s submitted data and saves it to the upload directory on the backend.
