Dropbox Uploader

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 respective values.

Usage

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.

License

Dropbox Uploader is licensed under the MIT License (MIT).

Troubleshooting

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("/absolute/path/to/the/cacert.file");

It is also possible to do this setting in the PHP ini file for PHP 5.3.7 and above. See curl.cainfo for the ini configuration and look for the CURLOPT_CAINFO option on curl_setopt (PHP manual).

Developing

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

Testsuite

Dropbox Uploader comes with a Phpunit testsuite located in the test folder.

To get the testsuite configured, copy phpunit.xml.dist to 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 curl.cainfo).

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;

export Dropbox_Credential_Password=your-password-goes-here

You can then invoke the testsuite from the projects root directory:

vendor/bin/phpunit test

Branching

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.

dropboxuploader's Issues

dropbox uploader was not working

For the past 4 days the dropbox uploader was not working . It was suddenly stopped. Please check this.

Return Direct Link after upload

is there a way to return the direct file link for download after upload

Great work. Would it be possible to list files in folder

You made a great work, expecially because your code allow the login to Dropbox by simply using the email and password. I would like your help to extend the functionality to list files in folder on dropbox.

Can you help me?

Not Working / Code 500 / example.php Line 27

Hello,

I am getting an error code 500 when simply try to run the example.php code on my personal website. It is hosted with Bluehost, and the error logs indicate that there is bad syntax on line 27 of the example.php, but I can't figure it out. Please provide more detailed instructions on how to use this code properly because it could be really useful!!! Do you know of code that uses the DropBox API to accomplish this type of upload?

Thanks,

David

I just put on my server , but it won't work, pls guide me where i am wrong.

Backups Failure on File Branch

The DB works great!

Default Database backed up successfully to BFI-2013-03-12T23-31-06 in destination Dropbox in 6598.73 ms.

The File Backup does not
Could not run backup because the file could not be saved to the destination.

They are the same destination same config.

403 Forbidden on Dropbox Upload

From today, when trying to upload to Dropbox, I'm getting a 403 Forbidden error in the response on line 130:
$data = $this->request(self::HTTPS_DROPBOX_COM_UPLOAD, $postData);

The response ($data) from that request looks like:

HTTP/1.1 100 Continue

HTTP/1.1 403 Forbidden
Server: nginx
Date: Fri, 25 Apr 2014 08:39:07 GMT
Content-Type: text/html; charset=utf-8
Transfer-Encoding: chunked
Connection: keep-alive
pragma: no-cache
cache-control: no-cache

Nothing has changed with my upload/backup script, can only assume it's a Dropbox issue or something has changed with the upload process.

File upload timestamps broken

Since ca. 2014-08-09 the dates of the files are set to the beginning of the Unix epoch 1/1/1970 (plus the offset in the account settings).

Scheduled to be fixed in one of the next versions (v1.1.19 or v1.1.20), the fix is currently in the development branch.

DropboxUploader warns about a deprecated feature on PHP 5.5

Hello there,

With error_reporting = E_ALL and display_errors = 1, DropboxUploader warns about a deprecated feature on PHP 5.5

The full message looks like this:
Deprecated function: curl_setopt(): The usage of the @filename API for file uploading is deprecated. Please use the CURLFile class instead in DropboxUploader->request() (line 125 of /xxx/drupal/sites/all/libraries/DropboxUploader/DropboxUploader.php).

Uploading the file still works, though.

Indeed, this depreciation is fully documented on the PHP website:

"CURLOPT_POSTFIELDS: The full data to post in a HTTP "POST" operation. To post a file, prepend a filename with @ and use the full path. The filetype can be explicitly specified by following the filename with the type in the format ';type=mimetype'. This parameter can either be passed as a urlencoded string like 'para1=val1&para2=val2&...' or as an array with the field name as key and field data as value. If value is an array, the Content-Type header will be set to multipart/form-data. As of PHP 5.2.0, value must be an array if files are passed to this option with the @ prefix. As of PHP 5.5.0, the @ prefix is deprecated and files can be sent using CURLFile."

(quoted from http://www.php.net/manual/en/function.curl-setopt.php)

It would be nice to fix it before PHP 5.5 becomes the mainstream version... May not happen anytime soon, I know ;)

Thanks,
Krizalys

Login unsuccessful

Since this morning, my cronjobs have returned the exception 'Login unsuccessful'. I can use the login credentials on the dropbox website, so that doesn't seem to be the case.

Has anyone else encountered this, and in that case, is there a fix for it?

Uploading 100mb++ problems

Hello,

I'm using your code to help me get video submissions from my website visitors. Thing is, when they upload 100mb+, It doesnt give you a confirmation of the upload nor the error. Is there something I can do to fix this problem? Thanks a lot!!

Regards,

Mike

Error: [DropboxUploader] #268698113 Login unsuccessful on version 1.1.22

please help me how to solve this

Get file link

How to get file link from dropbox to my php page ?

Quotes in the filename cause a 500 (Internal Server Error)

When I try to upload a file with single quotes in the filename, it fails with a 500 (Internal Server Error). Filenames with double quotes upload fine though. Any ideas?

Cheers.

Sporadic ERROR: Cannot extract token! (form action=https://dl-web.dropbox.com/upload)

A sporadic (two out of three)

ERROR: Cannot extract token! (form action=https://dl-web.dropbox.com/upload)

has been reported ca. 2013-01-09T00:00:00+00:00.

There is probably a mismatch with either the HTML or the token-pattern (most likely the later).

Dropbox filesize limit

According to Dropbox Page, filesize limit through the website is set to 10Gb.
https://www.dropbox.com/help/5/en

Last filesize limit was 300Mb

When I tried to change the dropbox configuration to 10Gb, I also get the upload failed error message
const DROPBOX_UPLOAD_LIMIT_IN_BYTES = 10737418240;
Any idea about this issue ?

Reference: #9

Error: [Exception] #0 File was not successfully uploaded from your computer.

While Up;loading an image came across this error.

Now it needs a CAPTCHA to login, any way to solve the problem?

error message:

err:{"recaptcha_response_field": {"message_text": "Please enter a CAPTCHA response."}}' in /var/www/DropboxUploader.php:189

#268697857 Curl error: (#60) SSL certificate problem: unable to get local issuer certificate

Uploader now ignores script if file already exists

I understand how for security purposes a change like this would be necessary, but in the scenario where I was using the script, I needed the files to get overwritten. Perhaps the upload function could contain a 4th parameter for overwrite that's false by default?

Then we can easily run the upload w/ the overwrite flag without any major changes to the system. Please advise.

It does not work with the new Dropbox's "Two-step verification"

If I set the new Dropbox's "Two-step verification" , then it will not work: the new location after login will be "/verify_code" and not "/home".

Add repo description and URL

Like at https://github.com/andreafabrizi/Dropbox-Uploader

DropboxUploader is final

There are no intended extension points so far for class DropboxUploader however the class has not been made final (e.g.: Final Classes: Open for Extension, Closed for Inheritance) and some properties and methods are misleadingly protected instead of private.

Caught exception: Login unsuccessful.

I am getting a very weird problem. The code works from my laptop, but it does not work on my server.
the certificate is the same. The DropBoxUploader is the same.

Any ideas?

Dropbox has a filesize limit/restriction on upload

@Tomaas reported a problem with uploading large files:

I seem to have the same issue on 1.1.7 while uploading a large file (> 300mo) after 5 minutes of upload:

Fatal error: Uncaught exception 'Exception' with message 'Upload failed!' in path/DropboxUploader.php:95
Stack trace:

@dexigner explained that there is a filesize limit of 300 MB:

Dropbox doesn't support uploading larger than 300MB (through the website, which this uploader uses)

DropboxUploader Still Broken

Re: #29

The work around specified seems to have broken... all it gives me now is:

Error: [Exception] #0 Login unsuccessful.

Any ideas on how to resolve?

Many thanks!

Error:#268698113 Login unsuccessful.

DropboxUploader has stopped working as of today..

[Feature] Make DropboxUploader a composer package

Packagist (https://packagist.org) is becoming lately a standard for managing dependencies in php projects. It also makes updating dependencies a piece of cake.

It would be great to see DropboxUploader in packagist.

Unsuccessful Login

Hi, I'm getting an unsuccessful login suddenly? It used to work fine until a few weeks ago. I'm guessing Dropbox has changed something in its setup after issuing out the new Dropbox link with MS Office... any ideas on how to fix it?

I am using Version bump v1.1.22 of the uploader.

Thanks

Exception: Cannot extract login CSRF token.

I think Dropbox may have changed the way they handle login. Since a few days, running phpunit tests returns this:

ESSSS.

How install your module

Hello,

I just don't figure our how to install your module.

Thank you

Remove version number in files

I think the version number should be removed from composer.json and DropboxUploader.php. Lets just have the version bump when you make a new tag for packagist.

Using Dropbox Uploader to upload a file from FTP to Dropbox

Hi, first of all thanks for this amazing project.

My issue:

Dropbox uploader can upload a file from local directory to dropbox. My question is, how can I use it to upload a file from FTP server to Dropbox?

For example: I have a file "backup.zip" in an FTP directory . So how can upload that file to Dropbox using FTP credentials.

I know I have to do this using cURL by editing function "request() " in DropboxUploader.php but I'm unable to do that. Please help...

Getting dropbox metadata

How do I get the dropbox metadata?

Getting an unsuccessfull Login

I know the login works as I can go to the webpage enter the credentials and have no issue.
I am using the files as is and I get this message. Any reason why?

Error: [DropboxUploader] #268501249 File '' does not exist or is not readable.

Hi there we get the following problem:
Error: [DropboxUploader] #268501249 File '' does not exist or is not readable.

Unable to login

I keep getting this error message when using the script.

It uploads almost 4 files but not all files

DropboxUploader No Longer Working

It would appear that Dropbox.com has changed its login system and no longer uses the hidden "t" token tag anymore. This has unfortunately stopped the script from allowing me to login.
Taking a look at the new page source, it would appear it was a deliberate attempt to stop scripts like DropboxUploader from function.
I'll keep trying to find a way around the new changes and post any success I have. Hopefully someone else might noticed something I've overlooked that allows the script to function correctly.

Echo The Path of The Uplaoded File On Success

Hi, How can I echo (print) the file path on success?

echo 'File successfully uploaded to your Dropbox!';

I tried adding " echo $_FILES['file']['name'] " after closing span:

echo 'File successfully uploaded to your Dropbox!' . echo $_FILES['file']['name'];

but it didn't work, for now I want just to echo of the uploaded file, I will add
" https://dl.dropboxusercontent.com/u/< USER ID>/'.
later because I want it for a project that's means I wont change the user id
thanks
