Dropbox Uploader is a PHP class which can be used to upload files to Dropbox, an online file synchronization and backup service.

You can use it to create a file upload form for your webpage, which uploads files to your dropbox. The exampe.php is a good start; just remove the email/password/destination fields and hardcode the respective values.

Another possibility is to create an email-to-dropbox gateway using procmail or something similar.

If you have too much time on your hands, you can even create a service to offer the above to non-technical persons.

require 'DropboxUploader.php';

$uploader = new DropboxUploader('[email protected]', 'password');
$uploader->upload('path/to/a/file.txt');

For a more complete usage example, see example.php.

Dropbox Uploader is licensed under the MIT License.

I'm getting the following error: Error: Cannot execute request: SSL certificate problem, verify that the CA cert is OK. Details: error:14090086:SSL routines:SSL3_GET_SERVER_CERTIFICATE:certificate verify failed

This means that the certificate of the Certification Authority (CA) that Dropbox uses for their SSL certificates is not installed on your system or PHP/cURL is not configured correctly to find it.

If you ARE the system administrator, try installing the CA certificates bundle to a system-wide location. If you use a package management system, this will ensure that they are kept up to date automatically. On Debian Linux for example, you can install the package ca-certificates.

If you are NOT the system administrator, you can download just the needed certificate and point DropboxUploader to it (before calling the upload() method):

$uploader->setCaCertificateFile("path/to/the/certificate.cer");
