Learn how to efficiently upload files with Ajax and Codeigniter, even without relying on Flash support

After experimenting with numerous Javascript plugins, I've reached a point where I need to seek advice. Can someone recommend the most effective method for file uploads using PHP CodeIgniter framework and Ajax?

Answer №1

My go-to tool for all uploads is Plupload. Its client-side focus means it can run smoothly on almost any web browser and platform, including .net and PHP.

Plupload cleverly detects browser compatibility by injecting Flash objects or Silverlight to enable features like chunked uploads (great for files over 2gb), speed control, queue management, and more.

This uploader is truly incredible, but unfortunately it's not as well-known as it deserves to be. After stumbling upon it, I was able to elevate the upload functionality on my sites to a Google or Facebook-style level with just a bit of tweaking - and all for free! Check out the possibilitieshere!

Answer №2

Recently, I had an excellent experience utilizing for a web application. This occurred approximately 12 months ago. Even though I employed Kohana instead of CI, the platform proved to be versatile in accommodating both frameworks.

Answer №3

ajax typically does not have built-in support for uploading files. One workaround is to submit a form to an iframe and then extract the response from there. Several plugins are accessible that streamline this process effectively.
