get checksum from file

[lam91]

I have a mySQL database that I would like to be able to use a form to
upload the information about a file (name, size, checksum) without having
to upload the file itself to the server.

Does anyone have any ideas.

I would be happy with either md5 or crc32

Not really a javascript problem. You will have to use a server side
scripting language such as PHP.

I would call a script on your sever by accessing a URL with the
embedded data, e.g.
http://www.yourdomain.com/cgi-bin/add_file_info.php?name=harry.jpg&size=4056&checksum=34587634587634

If would also recommend adding a password for the script.

e.g.
http://www.yourdomain.com/cgi-bin/a...hecksum=34587634587634&password=4563456346456

(encrypt the password with md5 or whatever before sending of course).

A server side script (e.g. PHP) would use $_GET['name'],
$_GET['password'] etc... and then use database calls to add the data to
the database.

Note the password is almost certainly required to stop others adding
their own data!

Hope that helps,
Thanks,
