Hi @jodeleeuw, actually I had the same problem. The csv file saved in my lab server is empty. Could you please explain a bit what you said "confirm that the PHP setup on your server is in order" and "the directory that the data is being written to is writeable"? In addition, I pasted my codes below. Did I do something wrong in my script? Or should I contact the lab engineer directly? Thank you in advance, Zifeng // send the data to the server
function saveData(name, data){
var xhr = new XMLHttpRequest();
xhr.open('POST', 'write_data.php'); // 'write_data.php' is the path to the php file described above.
xhr.setRequestHeader('Content-Type', 'application/json');
xhr.send(JSON.stringify({filedata: data}));
}
// initialize jsPsych
var jsPsych = initJsPsych({
show_progress_bar: true,
message_progress_bar: 'Progress',
on_finish: function() {
saveData(jsPsych.data.get().csv())
}
}); |
