There may be an easier way, but here's how I'm doing it. In the DTML Method that is the target of the post, do something like this (untested): <!--#if image--> <!--#call "REQUEST.image.seek(0, 2)"--> <!--#if "REQUEST.image.tell() > 0"--> <!--#call "REQUEST.image.seek(0)"--> <!--#call "manage_addImage(REQUEST.image.filename, file = REQUEST.image)"--> <!--#/if--> <!--#/if--> This will determine the file size of the file and if non-zero, will add it to the current folder. The second seek might not be necessary (it depends on whether manage_addImage() or whatever you do with the file does it). PS: It's multipart _encoding_, not encryption. Basically the browser just base64 encodes the data and sends it as text. HTTP/MIME supports the "binary" content transfer encoding for a multipart value, which is roughly 12.5% more efficient compared to base64, although I have never checked whether modern browsers support this. -- Alexander Staubo http://www.mop.no/~alex/ "`Ford, you're turning into a penguin.

Hello all,

second question of the day.

Right, how do you detect if an image has been provided for upload when using the MULTIPART encryption method on a form?

Basically, i have got a form that uploads three images to Zope and the user has the choice to upload between 1 and 3 pictures, so obviously, i need to check if the file boxes are empty or not. For example:

<INPUT TYPE="file" NAME="newImg">

at the zope end:

<!--#if newImg--> image is here <!--#else--> nothing there matey boy <!--#/if-->

does not work.... any ideas on how to check???

Please help, i am losing my hair very quickily....

Cheers,

P.
