Dropbox are removing support for the Public folder functionality.

This is a drop-in script replacement for your Dropbox public folder links.

As Dropbox no longer provides the service, DPFR runs on your web host instead. Files are still fetched in real-time from Dropbox using their API.

For example, while your old links might have looked like this:

https://dl.dropboxusercontent.com/u/123456/myfile.txt

Your new links will be sent via your web host and will look like this:

https://mysite.com/dropbox/myfile.txt

Instead of manually generating new Dropbox share links, this enables you to simply change the domain name for your links and be done with it.

This script is tailored to run on most conventional web hosts that support a modern version of PHP.

• PHP 5.5
• mbstring

Download the latest release version here. If you don't download the release version you will need to install dependencies via Composer.

DPFR does not support getting files directly from your Dropbox public folder. This is for security reasons. Instead, we will create a special "App folder", and move our files from the Public folder to the new App folder.

• Go to "My apps" in your Dropbox control panel.
• In step 1, create a "Dropbox API" app.
• In step 2, choose "App folder"
• In step 3, name your app to "Public folder replacement"
• You will be redirected to the app info page. Write down the App key and App secret
• In the Oauth2 section, click the "Generate" button and write down the Generated access token

App settings

Generating OAuth token

• Start by uploading the script to your web host.
• Copy the file config.sample.php to config.php.
• Edit config.php with the value obtained in the previous step.
  • appKey = App key
  • appSecret = App secret
  • accessToken = Generated access token
• Move or copy your files from the Public folder to the Apps/Public folder replacement folder.

You will need the mod_rewrite apache module enabled for this to work.

Add the following to your .htaccess file:

<IfModule mod_rewrite.c>
  RewriteEngine on
  RewriteCond %{REQUEST_FILENAME} !-f
  RewriteCond %{REQUEST_FILENAME} !-d
  RewriteCond %{REQUEST_URI} !=/favicon.ico
  RewriteRule ^(.*)$ index.php?q=$1 [L,QSA]
</IfModule>

Remove or comment out the ErrorDocument line.

If you have put the script in a subfolder you will need to modify the $urlPath variable by adding an additional line immediately below the line that defines this variable in index.php, eg

$urlPath = parse_url($_SERVER['REQUEST_URI'], PHP_URL_PATH);
$urlPath = preg_replace( "/^\/my_subfolder/", '', $urlPath);

replace 'my_subfolder' with the name of your folder.

Make sure to rewrite all your requests to index.php. For example this can be done using the following location block:

location / {
    try_files $uri $uri/ /index.php;
}

• Add file cache
• Nicer error page
