    Content type in uploads



    I am trying to determine how an upload form tells what type of file it is (gif, pdf, etc).

    I can find the extension, but does this hold true for a file uploaded from a mac?

    Is there some other way?
    The Miva_ValidateFileUpload function returns a whole string of strange stuff... Is this documented
    anywhere?

    Bill,
    There's a variable assigned in both functions:

    <MvFUNCTION NAME="Miva_ValidateFileUpload"
    PARAMETERS="field,filename,content_type">

    and

    <MvFUNCTION NAME="Miva_ProcessFileUpload"
    PARAMETERS="field,filename,status,tempfile,content _type,size">

    but I remember some discussion from some time ago that it doesn't always
    work (or rather, report it) correctly. Personally, I've never had any luck
    with it. Maybe it's fixed now.

    Bill M.

      From my experiments, it works so long as the server is Apache 1.3.6 or
      later (including 2.x) (no idea about other flavours of server).
      Unless specifically configured, Apache makes all its assumptions about
      MIME type based on extensions anyway. My upload scripts allow the user to
      specify filename on server, with a reminder to Mac users to add an
      extension. I've seen binaries corrupted when not given an extension.
      I'm working on a guide to uploads to go on mivascript.org

        That content type variable doesn't work as expected all the time for
        some reason, so I've resorted to parsing the filename out of whatever
        the l.filename variable is and then checking what the extension is for
        validity.

          As I said in the email:
          The Miva_ValidateFileUpload function returns a whole string of strange stuff... Is this documented
          anywhere?

            Apache 2.x

            Type returned is simply a mesh of stuff - nothing discernable - unless it is documented somewhere.

              That's what I was afraid of.

                Maybe its broken in Miva 4? I was getting valid MIME types when I
                evaluated the variable in 3.97
