Hi,
It's late and I've finaly managed to get blobs working. I just wanted to say
one thing, as it has caused me 10 - 12 hours of work before I found out
where the problem was.
DO NOT LEAVE WHITESPACE OR ANYTHING BEFORE A MGD_SERVE_ATTACHMENT() call!!!
(well almost. As long as it's between php tags and doesn't echo it's ok..)
I used Emiles code, did everything right, but could not make it work. After
a lot of poking around I tried to go to the uri
(/displaypage/artID/attachmentID) and god the errormessage that a header was
allready sent before the attachment header. The problem originated from a
white-space in code-global!!!!
I hope this posting might save someone some time.
