Hi

I currently have a HTML form with a file uplaod field within it, I would like to have a javascript check so that everyone HAS to upload a file to submit the form.

At the moment I have a javascript variable being set to True when the file field changes, and a check for true when it is submitted. But people are still not uploading files. Is there a better way to ensure a file is selected?

Hi logicjb:

There is no way to check if they have uploaded a file or not, (ie check to see if they have selected a valid upload file) unless this is done using some server-side language, after submission. Is that an option?
