File Upload to Dropbox from FORM with PHP

Question

I am so close. I am trying to create a form that will upload a file to my Dropbox, and I can get it to work using a file on the server with the code here:

$path = 'render.png';
$fp = fopen($path, 'rb');
ch = curl_init('https://content.dropboxapi.com/2/files/upload');
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
curl_setopt($ch, CURLOPT_PUT, true);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, 'POST');
curl_setopt($ch, CURLOPT_INFILE, $fp);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$response = curl_exec($ch);curl_close($ch);
echo $response;

I was sure this would work, but nope.....

$fp = fopen($_FILES['file'], 'rb');

Anyone have a quick fix for this?

Yes I have other code with the headers. The code at the top works, it will upload the 'render.png' file. The problem is getting the file from the form $_FILES['file'] to work. I get an empty file on the server. — Rex Reyes

This is your problem

$fp = fopen($_FILES['file'], 'rb');

You will need to use the tmp_name field from $_FILES as that is the location of the temporary file that PHP places in the temp folder.

$fp = fopen($_FILES['fred']['tmp_name'], 'rb');

Where 'fred' is the value of the name attribute in

<input type="file" name="fred".....`
                   ^^^^^^^^^^^

Take a look at Flysystem. I'm using it with Laravel but I believe it also works as a standalone.
