Code for APIv2
Sorry, I'm just a hack trying to upload a database backup to dropbox. API v1 worked fine but now I'm forced to migrate.
Here's the code I used to use, with the old API v1 commands and the new A...
If you want to call the Dropbox API directly, rather than via a library, you can makes HTTPS connections to the endpoints themselves. For example, to upload a file, you would use /2/files/upload. Calling that using curl in PHP would look something like this:
<?php $path = 'test_php_upload.txt'; $fp = fopen($path, 'rb'); $size = filesize($path); $cheaders = array('Authorization: Bearer <ACCESS_TOKEN>', 'Content-Type: application/octet-stream', 'Dropbox-API-Arg: {"path":"/test/'.$path.'", "mode":"add"}'); $ch = curl_init('https://content.dropboxapi.com/2/files/upload'); curl_setopt($ch, CURLOPT_HTTPHEADER, $cheaders); curl_setopt($ch, CURLOPT_PUT, true); curl_setopt($ch, CURLOPT_CUSTOMREQUEST, 'POST'); curl_setopt($ch, CURLOPT_INFILE, $fp); curl_setopt($ch, CURLOPT_INFILESIZE, $size); curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); $response = curl_exec($ch); echo $response; curl_close($ch); fclose($fp); ?>`<ACCESS_TOKEN>` should be replaced with the OAuth 2 access token.
The uploaded file path in Dropbox is defined by the "path" parameter in Dropbox-API-Arg.
So, for example, to upload a file "test_php_upload.txt" to root, the path parameter should be "/test_php_upload.txt".
Here's a version of my previous example that would do that:
<?php $path = 'test_php_upload.txt'; $fp = fopen($path, 'rb'); $size = filesize($path); $cheaders = array('Authorization: Bearer <ACCESS_TOKEN>', 'Content-Type: application/octet-stream', 'Dropbox-API-Arg: {"path":"/'.$path.'", "mode":"add"}'); $ch = curl_init('https://content.dropboxapi.com/2/files/upload'); curl_setopt($ch, CURLOPT_HTTPHEADER, $cheaders); curl_setopt($ch, CURLOPT_PUT, true); curl_setopt($ch, CURLOPT_CUSTOMREQUEST, 'POST'); curl_setopt($ch, CURLOPT_INFILE, $fp); curl_setopt($ch, CURLOPT_INFILESIZE, $size); curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); $response = curl_exec($ch); echo $response; curl_close($ch); fclose($fp); ?>
Hi Greg, thanks for your reply. I'm more than happy to use the Dropbox API rather than a 3rd Party. Not too fussed how it connects to be honest, as long as it does. How do I go about using the Dropbox API to connect and upload a file?

Brilliant Greg, that's working, thankyou.
One problem tho, I am uploading from a local path and it seems to be holding that path in to Dropbox. I just want to upload to the root folder in Dropbox, but every change I make seems to break the code.
Are you able to assist please?<?php $filename = "/db_" . date('d-m-Y').".zip"; $path = "/dir1/dir2/dir3/dir4" . $filename; $fp = fopen($path, 'rb'); $size = filesize($path); $cheaders = array('Authorization: Bearer 1234567890', 'Content-Type: application/octet-stream', 'Dropbox-API-Arg: {"path":"'.$path.'", "mode":"add"}'); $ch = curl_init('https://content.dropboxapi.com/2/files/upload'); curl_setopt($ch, CURLOPT_HTTPHEADER, $cheaders); curl_setopt($ch, CURLOPT_PUT, true); curl_setopt($ch, CURLOPT_CUSTOMREQUEST, 'POST'); curl_setopt($ch, CURLOPT_INFILE, $fp); curl_setopt($ch, CURLOPT_INFILESIZE, $size); curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); $response = curl_exec($ch); echo $response; curl_close($ch); fclose($fp);- Greg-DB

Thankyou very much for your help Greg, it is greatly appreciated.
Hi Greg,
I used the code that you provided and I was able to get it to work! It's different than the Postman Collection so the fopen definitely helped.
Anyway, I am coming across the problem of the api not changing the filename if there is already the same named file inside the folder, adding the (#) at the end of the file name.
I have "mode" : "add", "autorename" : true but still nada.
When playing around with the PHP Curl code from Postman, it worked as soon as I removed the drive letter in the path, but no luck here. Below is my code...any help is greatly appreciated...Thank you!
<?php$path = '\Documents\ShXXSh\Sample Report.pdf';$fp = fopen($path, 'rb');$size = filesize($path);$cheaders = array('Dropbox-API-Arg: { "path": "/Bxxx Ox Dxxxxxx/ShXXSh/Test7-9-21/Clue/Sample Report.pdf", "mode": "add", "autorename": true, "mute": false, "strict_conflict": false}','Dropbox-API-Path-Root: {".tag": "namespace_id", "namespace_id": "XXX"}','Dropbox-API-Select-User: dbmid:XXXXXXXXXXXXXXXXXXXXX','Content-Type: application/octet-stream','Authorization: Bearer XXXXXXXXXXXXXXXXXXXXXXXXXXXXX');curl_setopt($ch, CURLOPT_HTTPHEADER, $cheaders);curl_setopt($ch, CURLOPT_PUT, true);curl_setopt($ch, CURLOPT_CUSTOMREQUEST, 'POST');curl_setopt($ch, CURLOPT_INFILE, $fp);curl_setopt($ch, CURLOPT_INFILESIZE, $size);curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);$response = curl_exec($ch);echo $response;curl_close($ch);fclose($fp);?>
tahsiniWhat is the current behavior you're seeing after uploading? Do you not see any new file uploaded, or do you see the file being updated?
- Greg-DB
mabramsphoto Also, note that Dropbox won't consider it a conflict (that is, won't make a new file), if you upload the same contents as the existing file. You should upload different contents to see that behavior, or set "strict_conflict" to true if you want that behavior even for identical contents.
