On my site I use these two blocks of code to open protected files. I can open the files fine, and so can plenty of others. The problem is that at least one person complained that they couldn't open the file. This is what they had to say:
It opened Adobe, then an Adobe Reader window opened that stated "There was an error opening this document. This file cannot be found."
So that must mean that the streamfile($file) function (see below) did not return false, otherwise the message would have been "file was not found. please send [EMAIL PROTECTED]"
Does someone know what's going on here? Since I am not experincing this problem first handed, I really have no clue. Also, shouldn't this person get prompted if he wants to save it or open it with Adobe Acrobat?
Best Regards,
Scott Taylor
