Upload files or strings to Dropbox without the Dropbox API
Dropbox Uploader is a PHP class named
DropboxUploader which can be used to upload files to Dropbox, an online
file synchronization and backup service.
Its development was started before Dropbox released their API, and to work, it scrapes their website. So you can and probably should use their API now as it is much more stable. It's the Dropbox Core API in PHP.
You can use the Dropbox Uploader to create a file upload form for your website, which uploads files to your dropbox. The
example.php is a good start; just remove the email/password/destination fields and insert the
require 'DropboxUploader.php'; $uploader = new DropboxUploader('firstname.lastname@example.org', 'password'); $uploader->upload('path/to/a/file.txt');
For a more complete usage example, see
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):
To develop, it is most easy to checkout the hakre/DropboxUploader branch:
git clone -b development git://github.com/hakre/DropboxUploader cd DropboxUploader
Them retrieve the dependencies using Composer:
wget http://getcomposer.org/composer.phar php composer.phar install
Dropbox Uploader comes with a Phpunit testsuite located in the
To get the testsuite configured, copy
phpunit.xml and modify the Dropbox email and password
credentials and the SSL certificate store configuration (might be required if not set in PHP ini
If you want to use any of these settings from the commandline, set an environment variable with the same name. Environment variables have a higher priority than the XML configuration;
You can then invoke the testsuite from the projects root directory:
Development is done against hakre/DropboxUploader, the development branch. Create yourself a new branch from it and name it for every non-trivial changes you want to introduce.
Changes are then taken from feature branches into development and then into master.
Expect the development branch to get some force-pushes, just to keep in mind when your development branch diverges - better give your local branch a different name.
