Form verify phUploader so they MUST upload?

[Lex]

so, on most forms when you hit "submit" - or in this case Upload File(s) - if you have not filled out the form field (selected a drop down, put in some text, clicked a radio button, etc.) a warning pop-up comes up saying you need to do so. Essentially, a very simple method of form verification that they in fact filled out the fields.

How can that be added here so that at least 1 "choose file" must be completed? As it is, if you do not choose a file, it just sits there... would be nice to pop a warning message that says "you need to select and upload at least 1 file to proceed".

just to help prompt the user along.....

how can this be done? I am not good enough at php to know how to integrate a form check in the upload buttons and then pop a warning if they do not upload at least 1 file (as I have the ability set to upload a max of 4)

Sounds like JScript ... check out my site under www button. Click on Upload file. I think it does the same thing.
