Thanks for your reply, but this is not what I am looking for. I’ll try to explain a bit more:
I have a form made with CF7, where people can upload files. I would like to keep these files in my files directory. The problems are:
1) CF7 saves the files only temporarily. They are deleted automatically after some minutes.
2) Each file is stored (temporarily) in a subdirectory with a random number as directory name. So the path changes for every uploaded file. This is why I would like to have the exact upload path in the get_posted_data().
