I\'ve been trying to upload a simple text file for hours now but I still can\'t seem to get it working.
I keep getting invalid forms saying I\'m missing the \"file_s
You can't use jQuery to upload files asynchronously. You options are:
1.Submit the form "the usual way". This, of course, will refresh the page.
2.Use XHR: https://developer.mozilla.org/en-US/docs/Web/API/XMLHttpRequest/Using_XMLHttpRequest but beware that it's not supported on IE 8/9 . On those browsers you would need to fall back to an iframe and a form that posts to it, to mimic an asynchronous upload.
3.Use https://github.com/blueimp/jQuery-File-Upload It does what I described in 2. but spares you all the configuring.
