How to upload files to a Amazon S3 bucket subfolder via POST?

Question

I'm using plupload 1.4.2 to upload files directly to an Amazon S3 bucket. The question is, how can I upload them to a subfolder directly? What parameters should I configure in the policy or plupload object config?

Answer 1

Amazon S3 there is no concept of "folder" or "subfolder". Only objects. And an object has a "key".

If you wanna upload a file to a folder or subfolder, simply put the object key like this:

$key = "folder/subfolder/filename.extension";

And Amazon S3 will create the "imaginary" folder and subfolder.
