I have another (for me) tought nut to crack and would appreciate any help: I'm handling a submit-form (now in multi-part/formdata :) with a method called postit (from KMNetNews). I'm trying to detect within postit whether an image was included in the image1 property of the submit form (i.e. did the user decide to upload an image with the <input type=file name=image1> button): I.e. my hierarchy: ../../uniqueID - folderish article object edit - the submit form postit - the method that receives submit form data Inside postit I check: <dtml-if "image1"> The above always returns true, regardless of whether I've submitted an image via the edit-form or not. Same for: <dtml-if image1> <dtml-if "REQUEST.image1"> <dtml-if "_.str(REQUEST.image1)"> <dtml-if "_.str(REQUEST['image1'])"> <dtml-if "not _.str(image1)==''"> they always return TRUE regardless of whether I submitted an image via the submit's form image1 property. Furthermore: *<dtml-var image1>* returns: ** i.e. a null/empty/none contents! I tried to get the get_size, size and getSize methods to work with the image object*, but I always got an AttributeError, so I couldn't do the checking via size either. * as a matter of fact, I'm not sure image1 is an image object, if no image was included in the submit form? I also tried forcing the image1-property to an actual data type through HTML, in case no image was specified for uploading: <input type=file name="image1:boolean" value="off"> ... and tried to check with that too, but that didn't help either. I always get TRUE, whatever I do. So, how can I check whether an image was submitted or not? I'm beginning to sucpect I've misunderstood something gravely. Best regards, Samu Mielonen PS Once again I scoured the mailing list archives, but found no references to this problem.
