You could save yourself a whole lot of headaches by putting the files in the file-system, and storing only the path in the database... Also, IE and Netscape use different things to populate the filename box on the download dialog... One uses Content-disposition header(), and one uses whatever happens to be at the end of the path part of the URL. Thus, a goofy path like: http://wild.net/display.php/goofy.gif?id=42 (Where 42 is a GIF image of Goofy) actually works. The web-server and PHP ignore that goofy.gif crap, and the browser is fooled into thinking you're downloading a static file. ----- Original Message ----- From: "Boget, Chris" <[EMAIL PROTECTED]> Newsgroups: php.general Sent: Tuesday, January 09, 2001 4:44 PM Subject: [PHP] Serving files form DB > I'm storing files in a mySQL table that looks like this: > > | file_name | varchar(100) | | MUL | | | > | file_description | text | YES | | NULL | | > | file_type | varchar(50) | | | | | > | file_size | int(10) unsigned | | | 0 | | > | added_by | varchar(10) | | | | | > | access_types | text | YES | | NULL | | > | access_users | text | YES | | NULL | | > | file_num | bigint(10) unsigned | | PRI | 0 | > auto_increment | > | bin_data | blob | | | NULL | | > > the "file_type" field stores the actual data type for the file > (such as 'application/msword', etc).
