UpDrive: Allow anyone to upload files to your Google Drive with a simple webform

With a simple webform, hosted on your own webserver, anyone you want can upload files to your Google Drive, in folders you specify. UpDrive is a project written in PHP. It uses the Google API client PHP SDK.

Requirements

• PHP 5.5 or newer
• A Google API project

Install UpDrive

Install UpDrive and its dependencies with Composer with this command: $ php composer.phar create-project lutsen/updrive [project-name] 0.5
(Replace [project-name] with the desired directory name for your new project)

Rename config_example.php to config.php and add:

• your server paths
• the names of the folders people can upload to

Create a Google API project web application

Download the json client secret file from you Google API project, rename it to client_secret.json and add it to the UpDrive root directory.

How to create a Google API project

1. Go to the Google API Console. Create a new one by selecting Create a new project.
2. In the sidebar under "API Manager", select Credentials, then select the OAuth consent screen tab. Choose an Email Address, specify a Product Name, and press Save.
3. In the Credentials tab, select the New credentials drop-down list, and choose OAuth client ID.
4. Under Application type, select Web application. In the Authorized Redirect URIs field, enter the URL of the oauth2callback.php page.
5. Press the Create button.
6. Download the client_secret json file (the download button is on the right).
7. Rename this file to client_secret.json and add it to the UpDrive root directory.

Use UpDrive

The first time you access UpDrive, you have to connect to the Google account of the Google Drive you want to use. After authorising the UpDrive web application, the OAuth credentials are saved in the credentials.json file. Now people can use the webform to upload files to your Google Drive.

Reconnect UpDrive

To reconnect UpDrive to a Google account, delete the credentials.json file from your webserver and access UpDrive again. Now you can reconnect.
