DropboxAPI

Recommended Posts

ProcessWire DropboxAPI on GitHub: https://github.com/clipmagic/DropboxAPI

 

This module is a wrapper for Kunal Varma's Dropbox PHP SDK https://github.com/kunalvarma05/dropbox-php-sdk

It was created to perform a specific function for a client, ie upload PDF files on a PW website to a specific Dropbox account folder.

The PDF files, created using @Wanze's excellent PagesToPdf module using the WirePDF functions, are generated from Formbuilder forms completed by front-end site visitors.  Works a treat!

There's more that could be done to allow ProcessWire to take advantage of all the features of the SDK, eg downloads, multiple Dropbox accounts, etc. You are welcome to request changes and/or fork the GitHub project to extend the feature set.

Enjoy!

System requirements

  • PHP 5.6.4 or greater
  • Composer
  • The PHP mbstring extension

General information

This module enables you to access a single Dropbox (www.dropbox.com) account to upload files from a ProcessWire website.

All kudos to (https://github.com/kunalvarma05/dropbox-php-sdk) for the PHP API.

First steps

  • Visit (https://www.dropbox.com/developers) and read the documentation.
  • Log into Dropbox and create a new application. It's recommended to limit ProcessWire App access to a specified folder
  • Make a note of the App key, the App secret and the name of the Dropbox folder

Installation

  • Download the zip file into your site/modules folder then expand the zip file.
  • Next, login to ProcessWire > go to Modules > click "Refresh". You should see a note that a new module was found. Install the DropboxAPI module.
  • Configure the module with your App key, App secret and your Call Back URL

You need to generate a Dropbox access token to enable your site to communicate with the nominated Dropbox account. Dropbox will generate a token for you or you can create a page for the front end of your ProcessWire site with a template to submit the token request to Dropbox, eg:

    <?php namespace ProcessWire;
    
    $drop = $modules->get('DropboxAPI');
    
    if ($input->get->code && $input->get->state) {
        $code = $sanitizer->text($input->get->code);
        $state = $sanitizer->text($input->get->state);
    
        //Fetch the AccessToken
        $accessToken = $drop->getAccessToken($code, $state);
    
        echo "Copy/paste this code into the module configuration: " .  $accessToken;
    
    } else {
        echo  "<p><a href='" . $drop->getAuthURL() . "'>Log in with Dropbox</a></p>";
    }
    ?>

Once you have entered the token in the module configuration, you can unpublish this page.

Usage

Read the dropbox-php-sdk documentation!

An example template for sending a file to a Dropbox App folder from ProcessWire:

    <?php namespace ProcessWire;
    use Kunnu\Dropbox\Dropbox;
    use Kunnu\Dropbox\DropboxApp;
    use Kunnu\Dropbox\DropboxFile;
    
    // send pdf to Dropbox
    $drop = $modules->get('DropboxAPI');
    $app = new DropboxApp($drop->app_key, $drop->app_secret, $drop->authorization_code);
    if ($app) {
        //Configure Dropbox service
        $dropbox = new Dropbox($app);
        $dropboxFile = new DropboxFile('/path/to/myfilename.pdf');
        $file = $dropbox->upload($dropboxFile, "/myfilename.pdf", ['autorename' => true]);
        //Uploaded File meta data
        if ($file) {
            $success = $file->getName() . " uploaded to Dropbox";
            $drop->log($success);
        }
    }

Thanks for sharing this module, @psy! Will definitely give this a try soon.

Just one observation at this point: only Process modules should have the Process prefix in their name, and since this isn't a Process module (i.e. it doesn't extend Process), I'd suggest considering another name for clarity. Perhaps just dropping the Process prefix? :)

@teppo

Thanks for the tip. Was a bit confused about naming conventions. The module doesn't render anything so not Markup, and to me, it was a 'process', although granted, not a PW process. 

Done. Let me know if there are any problems relating to the name change.

At this point my best suggestions would be DropboxAPI, just plain Dropbox, or perhaps DropboxUpload... though that last one only if you are sure that you'll never add anything other than upload support for it :)

Tip:

By default the Dropbox App is in Development mode and allows only one user - you. When you apply for a token you may get a Dropbox notification saying you need more users. Simply go back into your Dropbox App configuration and click on the button to the right of this setting. You'll automatically be granted 500 development users.

Should you need more than 500 users, you'll need to apply to Dropbox for Production status for your App and totally outside the scope of this ProcessWire Dropbox API module.

Hi!

Great module. Two requests:

  • Could the token step be incorperated into the admin settings or a required Process module?
  • I've been thinking for ages to whether it was possible to view the contents of a folder from dropbox on your site and create public links to files - use case: upload your resources to this folder in dropbox and they'll automatically appear on the site?

Thanks!

@benbyf

Thanks Ben

  • The token request could be on the admin side BUT the Dropbox call back URL must be a publicly viewable page to receive the token. I chose to put both the request and response on the same page and then unpublish the page once I'd received the token.
  • According to the documentation, https://github.com/kunalvarma05/dropbox-php-sdk/wiki/Working-with-files the answer is yes. The PW module really does little more than authenticate the user and allow you to create the $dropbox object (as in example above for sending a file). Add all the appropriate "use" namespace statements in your template and you'll have full access to the API, including the ability to List Folder Contents

Tested and confirmed you can do this. Simple example (no paging although that's possible too):

<?php namespace ProcessWire;

use Kunnu\Dropbox\Dropbox;
use Kunnu\Dropbox\DropboxApp;
use Kunnu\Dropbox\DropboxFile;

$drop = $modules->get('DropboxAPI');
//Configure Dropbox Application
$app = new DropboxApp($drop->app_key, $drop->app_secret, $drop->authorization_code);
//Configure Dropbox service
$dropbox = new Dropbox($app);
$listFolderContents = $dropbox->listFolder(""); //root folder is the folder you nominated in the Dropbox App config. Refer doco
$items = $listFolderContents->getItems();
?>
<ul>
    <?php foreach ($items as $item) : ?>
       <li><?=$item->getName()?></li>
    <?php endforeach; ?>
</ul>

As for download links, you could use the Dropbox Chooser https://www.dropbox.com/developers/chooser#javascript or create your own with javascript.

Hi sorry not big PHP dev (mainly front end) and none of the module makes sense to me (lots of namespaces). getting errors like this: Class 'Kunnu\Dropbox\DropboxApp' not found in /srv/users/serverpilot/apps/fabricacapital/public/site/templates/dropbox.php:8 on the public pages implementing either of teh code demos above. Any help would be ace!

Also I mamanged to get a app code directly in the dropbox developer portal, so no need for the token generating step above.

Hi @benbyf

Yeah, the namespace stuff did my head in too! Adding them at the top of the page template under <?php namespace ProcessWire; was the only way I could get it to work. Once they're there, and the PW module is loaded, it's a matter of following the dropbox-api-sdk documentation to the letter.

Ooops! Just realised the GitHub version of the module has an error. Will upload fix.

soooo confused about this module, how did you get it to work?!

e.g. /vendor/ and autoload.php folder/files don't exist in the repo.

Did you do the upgrade to DropboxAPI.module ? The original version in GitHub looked for the wrong path to the autoload.php of the SDK files. This is what it should be:

require_once dirname(__FILE__) . '/dropbox-php-sdk/vendor/autoload.php';

From what I can gather from the error you mentioned, the SDK files aren't being loaded. The updated code should fix that.

yep, updated. But like i mentioned there is simply no file called autoload in the repo... let allow a folder called vendor

@benbyf are you using composer? Or manually downloading the packages?

vendor directory and autoload.php is created when you require a package with composer.

Good point, not needed to use composer with Processwire yet, so didnt reach for it this time. I'm guess thats the problem then? Also no mention in teh installation notes either but might because i dont know what to look for maybe?

Am i right in saying using composer also makes a module incompatible with the PW admin module installer?

Just in case its useful for anyone, this is my function for creating a folder list with public links to files:

<?php namespace ProcessWire;

      WHY?
      This module was built to fill the gap between simple $pages->find() operations and complex SQL queries.
      The problem with $pages->find() is that it loads all pages into memory and that can be a problem when querying multiple thousands of pages. Even $pages->findMany() loads all pages into memory and therefore is a lot slower than regular SQL.
      The problem with SQL on the other hand is, that the queries are quite complex to build. All fields are separate tables, some repeatable fields use multiple rows for their content that belong to only one single page, you always need to check for the page status (which is not necessary on regular find() operations and therefore nobody is used to that).
      In short: It is far too much work to efficiently and easily get an array of data based on PW pages and fields and I need that a lot for my RockGrid module to build all kinds of tabular data.

      Basic Usage

      Hello for all,
      ConfigurationForm fieldtype module is one my experiment from 2016.
      Main target to build this module was to store multiple setup and configuration values in just 1 field and avoid to use 1 db table to store just single "number of items on page", or another db table to store "layout type" etc. Thanks to JSON formatted storage this module can help you to reduce number of PW native fields in project, save DB space, and reduce number of queries at front-end.
      Install and setup:
      Download (at the bottom ), unzip and install like any other PW module (site/modules/...). Create some filed using this type of field (ConfigurationForm Fieldtype) Go to field setup Input tab and drag some subfields to container area (demo). Set "Name" and other params for subfields Save and place field to templates ("Action tab") How to use it:
      In my case, I use it to store setup and configurations values, but also for contact details, small content blocks... (eg. "widgets").
      Basic usage example:
      ConfigForm fieldtype "setup" has subfields:
      "limit", type select, option values: 5, 10, 15, 20
      "sort", type select, option values: "-date", "date",  "-sort", "sort"
      // get page children (items) $limit = isset($page->setup->limit) ? $page->setup->limit : 10; $sort = isset($page->setup->sort) ? $page->setup->sort : '-sort'; $items = $page->children("limit=$limit, sort=$sort");  
      Screenshots:


       
      Notes:
      Provide option to search inside subfields Provide multilanguage inputs for text and textarea field types Provide option for different field layout per-template basis Do not place/use field type "Button" or "File input" because it won't works. Please read README file for more details and examples Module use JSON format to store values. Text and textarea field types are multilanguage compatible, but please note that main target for this module was to store setup values and small content blocks and save DB space. Search part inside JSON is still a relatively new in MySQL (>=5.77) and that's on you how and for what to use this module.
      Thanks:
      Initial point for this fieldtype was jQuery plugin FormBuiled and thanks to Kevin Chappel for this plugin.
      In field type "link" I use javascript part from @marcostoll module and thanks to him for that part.

      Hi guys I'm relatively new to PW and just finished developing a page for a client. I was able to include all necessary functionality using the core fieldtypes but now I it seems that I need to extend them with a custom one. What I need is a simple button, that copies the absolute url (frontend not PW-backend) of the page which is currently edited to the clipboard. As this feature is only needed inside a specific template, I tend to use a custom fieldtype which provides this feature. I've been looking inside the core modules code (eg. FieldtypeCheckbox.module) but I don't really get the structure of it and how its rendered to the admin page. I also didn't find a lot of tutorials covering custom fieldtypes.
      Maybe some of you could give me some tips on how to write a basic custom fieldtype that renders a button which copies the value of
      page->httpUrl() to the clipboard using JS. Thanks!

      Some of you might have followed the development of this module here: https://processwire.com/talk/topic/15524-previewdiscussion-rockdatatables/ . It is the successor of "RockDataTables" and requires RockFinder to get the data for the grid easily and efficiently. It uses the open source part of agGrid for grid rendering.
       
      WHY?
      ProcessWire is awesome for creating all kinds of custom backend applications, but where it is not so awesome in my opinion is when it comes to listing this data. Of course we have the built in page lister and we have ListerPro, but none of that solutions is capable of properly displaying large amounts of data, for example lists of revenues, aggregations, quick and easy sorts by the user, instant filter and those kind of features. RockGrid to the rescue 😉 
       
      Features/Highlights:
      100k+ rows Instant (client side) filter, search, sort (different sort based on data type, eg "lower/greater than" for numbers, "contains" for strings) extendable via plugins (available plugins at the moment: fullscreen, csv export, reload, batch-processing of data, column sum/statistics, row selection) all the agGrid features (cell renderers, cell styling, pagination, column grouping etc) vanilla javascript, backend and frontend support (though not all plugins are working on the frontend yet and I don't plan to support it as long as I don't need it myself)  
      Limitations:
      While there is an option to retrieve data via AJAX the actual processing of the grid (displaying, filtering, sorting) is done on the client side, meaning that you can get into troubles when handling really large datasets of several thousands of rows. agGrid should be one of the most performant grid options in the world (see the official example page with a 100k row example) and does a lot to prevent problems (such as virtual row rendering), but you should always have this limitation in mind as this is a major difference to the available lister options that do not have this limitation.
      Currently it only supports AdminThemeUikit and I don't plan to support any other admin theme.
