I'm trying to build a basic web application using the Dropbox API. I have the file upload/folder listing etc. working but cannot find in the documentation how to force the file to download to the user's browser. Is this possible?
If it is can someone point me in the right direction? I'm using the standard PHP SDK.
Dropbox.com: How do I force a file to download from the web
Force a file or folder to download
To cause the browser to download a file or folder rather than display
it, you can use dl=1 as a query parameter in your URL. For example:
https://www.dropbox.com/s/qmocfrco2t0d28o/Fluffbeast.docx?dl=1 Note
that the original share link URL may contain query string parameters
already (e.g. dl=0), so app developers should make sure to properly
parse the URL and add or modify parameters as needed.
And if that doesn't suffice you can check Wikihow: How to Force a File to Download from the Web on Dropbox, with nice screenshots.
If this is not what you had in mind you have clarified that in your question. You still can do that now.

I am in a situation where I have to upload a PDF file through an API, all of the examples that I have encountered point towards a specified file location, where uploaded through a form or in a specified location on a computer/server.
The issues arises that the PDFs that I have to attach are being provided to me as direct download links. Are there any solutions that would work off of my Virtual Machine setup of Dreamfactory?
So are you trying to POST a PDF file using DF files service? And are you saying the only way to get the file is via a direct download link? I'm not sure I fully follow what you are trying to achieve but the DreamFactory scripting may be able to help you implement this.
So far, I've built a PHP script that downloads to a remote server of mine a file from Internet, provinding its URL (I've used this piece of code to download to the server).
Now I would like to upload the downloaded file on Google Drive using its API.
My question is: Is there a way to download the file directly to Google Drive, without using the server? Or I am forced to download the file first to the server and then upload it to Google Drive?
Thank you
I doubt if you can 'make' google drive get file from an external location...
However you do have an option to create a shortcut to the external file, if that suits you.
Also, If you wish continue direct upload you may refer this.
As far as I know the API doesn't allow to push files from another referer than the one that's calling the API. So, long story short:
First you need to download the file to your server, then upload it to gDrive from your server.

I have a site built in PHP and we have some PHP pages that require logging in that produce links to PDFs. The problem is that those PDFs (which were copied out to Amazon Cloudfront) were indexed and available for searching.
What is the easiest way to stream an existing PDF to the browser, making it so that the user has to login to be able to see the document? I'm hoping that there is some simple Header code or something where I can say "load this file on the server that's not accessible on the web and output it as PDF".
Any thoughts/suggestions?
Thanks!
You can use htaccess (or similar) to redirect any requests for a .pdf document to a PHP script, passing the requested file name. The script can then validate the log-in credentials, and if the user is logged in it can then send PDF headers, fetch the PDF document (file_get_contents) and output the code.
You can either block access to files (as mentioned in the other answer) or (more cleverly, IMHO) you can pass the file through to the browser after checking credentials (or doing pretty much anything) in PHP. There are code examples and a discussion here: http://bytes.com/topic/php/answers/159354-pass-through-any-file
I am placing href links to remote files for download simple as this with ajax:
Link
but it opens in new window and cuts off http:// and returns not found error, although if i refresh the page it will start downloading the file.
Maybe i could specify the content type and pass with header somehow but i dont want to pass the file through my server, it should download it from remote link.
Hope i could explain well.
Thank you.
sounds like the remote site has some protection against hot linking.
Are you certain that the link is correct? Try testing it externally first using an online flash player such as http://www.flvplayeronline.com/ . If the video plays then as #EvilSpaceHamster stated it could be a permissions issue on the server. I noticed you stated download? Is this a requirement or do you just want to grant the user access to view the file?
I would like to start a upload and download website for huge files (up to 1gb). I thought that it would be better to download the files using FTP (with PHP), because this protocol is especially used for these types of transfers.
The cliënt gets an email, including a download link to download the file (like yousendit.com). When they click on the link a download box appears. My problem is that I don't know how to show a download box using ftp and php. I have read that it isn't possible to immediately download a file by PHP, using FTP. Is this correct?
Do I have to create a temporary files on the server to let the client download the file? If yes, is this also a good solution for huge files?
What do you advice me to give the clients the possibility to download these huge files?
Thanks for your reply!
You can generate unique address based on session_id (create this folder on runtime and move huge file there) and redirect user to this link
For example, you have file huge.tgz
1. Send you client link http://***/user/john/file/huge.tgz
2. Ask user for auth in this page if they lost session
3. get session id
4. create on your server folder with name equals session id and move huge.tgz here
5. redirect user to unique ftp link ftp://***/17oe5kf8iYmpt66bjs89hcuo83/huge.tgz
You should disallow list files and directories on ftp server
Can't you send them an FTP link ? Why do you need PHP?
ftp://ftp12.freebsd.org/pub/FreeBSD/ls-lR.gz
You probably want to use PHP to handle everything but the file transfer. Once you have done all the checks you want you can redirect the browser to the file specifying the protocol as ftp. though you won't be able to have a progression bar in your site, the browser/ftp app will probably display one.
