Get folder name when upload media

Hello,

I search a solution to a recent problem, I made a plugin to automatically create a post when I upload an image on the media uplaoder (to create quickly many posts with images).

That’s work well but now I try to assign them in categories, I don’t want to have to do this by manual.

So I look for a solution to define the category with the upload, like maybe put all the images in a folder with the category name.

But I can’t find a way to retreive the folder name.

Any solution? Ideas?

Thanks,

Etienne
