Content Disposition - Download files
Hello, i want to send an image or a pdf to a browser not for viewing but for downloading. I've written this code: <dtml-call "RESPONSE.setHeader('Content-type', 'application/force-download')"> <dtml-call "RESPONSE.setHeader('Content-Disposition', 'attachment; filename=filename.gif')"> now i have to send the file as a binary flow, but i don't know how to do. Can you help me? Thanks, Bruno

Do you plan to always send the file for download? Then you just put a script name into "precondition" field of the object. The script could be something like: (Python script) context.REQUEST.RESPONSE.setHeader('Content-Disposition','attachment; filename=%s' % context.getId()) Regards Tino Wildenhain

context.REQUEST.RESPONSE.setHeader('Content-Disposition','attachment; filename=%s' % context.getId()) Nice idea, but what i need is different. In PHP there is a function called readfile, i'm sure there is something also in Zope, but i'm not able to find it!

No, I can tell you you are on the wrong path. Zope isnt PHP. Dont try to follow old PHP patterns with Zope. (Of course you could read the file object data but this inefficient) What is the problem with above solution? Regards Tino

Maybe if you stop torturing yourself (and us!) with dtml. The above should be either an external method, or a method of a content object from a product. cheers, Chris -- Simplistix - Content Management, Zope & Python Consulting - http://www.simplistix.co.uk

<dtml-call "RESPONSE.setHeader('Content-type', 'application/force-download')"
<dtml-call "RESPONSE.setHeader('Content-Disposition', 'attachment;filename=filename.gif')" <dtml-var "_['filename.gif'].data">
But there is no reason why you wouldn't want to do that with a Python script. HTH

You add an additional '<dtml-var "index_html(REQUEST, RESPONSE)">' It might be necessary to avoid white space around your tags. Therefore, it is better to do this in a Python Script rather than a DTML object. There, it would look like: r = container.REQUEST; R = r.RESPONSE R.setHeader(...) # your additional headers ... return context.index_html(r, R) -- Dieter
