Using PHP to save file with unknown file name
问题 I'm working on an online experiment (using the jsPsych library) where participants (each with a code number randomly assigned by the script) will record a number of .wav files. I then want to upload to the server with names that include the participant's code number and the item number associated with that recording. Each participant will be creating something like 36 different short .wav files. It looks like recorderjs and recordermp3.js are what I need to record the audio on the browser
