Ajax file upload

Question

I want to upload a file using Ajax and php. I have a form with <input type="file"> tag. I want when user browses a file and clicks on submit, the file to be uploaded without a refresh. How should I do this ? It does't matter if refresh occur but i want to upload file with help of ajax.

Answer 1

• Use a hidden iframe and set your form's target to that iframe's name. This way, when the form is submitted, only the iframe will be refreshed.
• Have an event handler registered for the iframe's load event to parse the response.

Answer 2

I did it with this jquery plugin. It pretty much mimics standard jquery ajax functionality, but also allows you to send data using iframe. No flash involved, pure javascript.

This plugin uses XHR for uploading multiple files with progress-bar in FF3.6+, Safari4+, Chrome and falls back to hidden iframe based upload in other browsers, providing good user experience everywhere. check this: http://valums.com/ajax-upload/
