File Upload Element Attributes – No URL? Filesize?

[katw]

Hi a few questions regarding File Upload elements:

Question 1: No URL

Looking at your getValueHTML() function for File Upload elements I have a question.

Under what circumstance? would a file upload element have no URL?

Question 2: File size

File size attribute is that in bytes? So dividing value by 1024 will give k?

Question 3: File type

Is that MIME type? And how is that determined at time of upload? By extension?

Question 4: Security

If a file type is not in in the included list. Can a user rename file and bypass the check?

Is there a way to protect the files once uploaded? Ie must be logged in to access? Any suggestions?

Thanks again

4. Ok, thought so

5. Was aware of this but didn’t know how it would affect the plugin when saving files. Is it excused from security check?
