Sending audio file created with RecordRTC to my server - xmlhttprequest

Question

I am new to working with Javascript, PHP, and with servers generally. I am working on a web page that will record audio from the user and save it to my server, using RecordRTC. I'm a bit confused about the XMLHttpRequest portion - how do I alter the following code to send to my server instead of the webrtc server?
function uploadToServer(recordRTC, callback) {
var blob = recordRTC instanceof Blob ? recordRTC : recordRTC.blob;
var fileType = blob.type.split('/')[0] || 'audio';
var fileName = (Math.random() * 1000).toString().replace('.', '');
if (fileType === 'audio') {
fileName += '.' + (!!navigator.mozGetUserMedia ? 'ogg' : 'wav');
} else {
fileName += '.webm';
}
// create FormData
var formData = new FormData();
formData.append(fileType + '-filename', fileName);
formData.append(fileType + '-blob', blob);
callback('Uploading ' + fileType + ' recording to server.');
makeXMLHttpRequest('https://webrtcweb.com/RecordRTC/', formData, function(progress) {
if (progress !== 'upload-ended') {
callback(progress);
return;
}
var initialURL = 'https://webrtcweb.com/RecordRTC/uploads/';
callback('ended', initialURL + fileName);
listOfFilesUploaded.push(initialURL + fileName);
});
}
Via my web hosting provider, I'm using an Apache server, phpMyAdmin, and a mySQL database. Do I just replace
makeXMLHttpRequest(https://webrtcweb.com/RecordRTC/
with "https://mywebsite.com" and replace
var initialURL = 'https://webrtcweb.com/RecordRTC/uploads/';
with the path to the file I created to hold these audio files (https://mywebsite.com/uploads)? Then set permissions for that folder to allow public write capabilities (this seems unsafe, is there a good method)?
This is the makeXMLHttpRequest function:
function makeXMLHttpRequest(url, data, callback) {
var request = new XMLHttpRequest();
request.onreadystatechange = function() {
if (request.readyState == 4 && request.status == 200) {
callback('upload-ended');
}
};
request.upload.onloadstart = function() {
callback('Upload started...');
};
request.upload.onprogress = function(event) {
callback('Upload Progress ' + Math.round(event.loaded / event.total * 100) + "%");
};
request.upload.onload = function() {
callback('progress-about-to-end');
};
request.upload.onload = function() {
callback('progress-ended');
};
request.upload.onerror = function(error) {
callback('Failed to upload to server');
console.error('XMLHttpRequest failed', error);
};
request.upload.onabort = function(error) {
callback('Upload aborted.');
console.error('XMLHttpRequest aborted', error);
};
request.open('POST', url);
request.send(data);
}

Please make sure that your PHP server is running top over SSL (HTTPs)
Create a directory and name it uploadFiles
Create a sub-directory and name it uploads
Structure of the directories:
https://server.com/uploadFiles -> to upload files
https://server.com/uploadFiles/uploads -> to store files
index.php
Now create or upload following index.php file on this path: https://server.com/uploadFiles
<?php
// File Name: "index.php"
// via https://github.com/muaz-khan/RecordRTC/tree/master/RecordRTC-to-PHP
foreach(array('video', 'audio') as $type) {
if (isset($_FILES["${type}-blob"])) {
echo 'uploads/';
$fileName = $_POST["${type}-filename"];
$uploadDirectory = 'uploads/'.$fileName;
if (!move_uploaded_file($_FILES["${type}-blob"]["tmp_name"], $uploadDirectory)) {
echo(" problem moving uploaded file");
}
echo($fileName);
}
}
?>
Why sub-directory?
Nested directory uploads will be used to store your uploaded files. You will get URLs similar to this:
https://server.com/uploadFiles/uploads/filename.webm
Longer file upload issues:
https://github.com/muaz-khan/RecordRTC/wiki/PHP-Upload-Issues
upload_max_filesize MUST be 500MB or greater.
max_execution_time MUST be at least 10800 (or greater).
It is recommended to modify php.ini otherwise create .htaccess.
How to link my own server?
Simply replace https://webrtcweb.com/RecordRTC/ with your own URL i.e. https://server.com/uploadFiles/.
