How to move ionic video capture to file_put_contents() in php - php

Question

we created an ionic app which captures video but we are facing challenges saving this video to a directory in on the server. I have searched online for this but couldn't find a tutorial about it.
On the code below, the video name was saved in the videos folder instead of the actual video
//Upload video php part
$postjson = json_decode(file_get_contents('php://input'), true);
if(!empty($postjson['video'])){
$video = $postjson['video'];
$now = DateTime::createFromFormat('U.u', microtime(true));
$id = $now -> format('YmdHisu');
$upload_folder = "videos";
$path ="$upload_folder/$id.mp4";
$actualpath = "http://url/incident/api/$path";
file_put_contents($path,$video);
}
On the ionic part, I have this:
captureVideo() {
let options: CaptureVideoOptions = {
limit: 1,
duration: 120
}
this.mediaCapture.captureVideo(options).then((res: MediaFile[]) => {
let capturedFile = res[0];
let fileName = capturedFile.name;
let dir = capturedFile['localURL'].split('/');
dir.pop();
let fromDirectory = dir.join('/');
var toDirectory = this.file.dataDirectory;
this.ivideo = fileName;
this.viddir = dir;
console.log("video captured "+this.ivideo);
this.file.copyFile(fromDirectory , fileName , toDirectory , fileName).then((res) => {
this.storeMediaFiles([{name: fileName, size: capturedFile.size}]);
},err => {
console.log('err: ', err);
});
},
(err: CaptureError) => console.error(err));
}
Sending to the server using post method in code summary:
var headers = new Headers();
headers.append('Content-Type', 'application/json' );
//headers.append('Access-Control-Allow-Methods', 'POST' );
headers.append('Content-Type', 'multipart/form-data');
let options = new RequestOptions({ headers: headers });
let data = {
aksi : 'insert_incident',
title: this.title.value,
descr: this.descr.value,
images : this.cameraData,
video: this.ivideo,
};
this.http.post(this.global.serverAddress+"api/getCategories.php", data, options)
.map(res => res.json())
.subscribe(res => {
loader.dismiss()
if(res=="Done"){
let alert = this.alertCtrl.create({
title:"Done",
subTitle: "Sent",
buttons: ['OK']
});
alert.present();
}else
{
let alert = this.alertCtrl.create({
title:"ERROR",
subTitle:(res),
buttons: ['OK']
});
alert.present();
}
}
