Hi Jones,
The code you need to write in the PHP script is reported at step 4 here: https://doc.pcibex.net/how-to-guides/recording-multimedia/#server-setup
Also, make sure you have at least one blocking upload trial before the results are sent to your server, or you’ll risk hitting “send results” before the upload completes and you won’t have lines in your results file reporting the filename(s) of the uploaded file(s)
