php file :

    $id  = $now->format('YmdHisu');

    $upload_folder = "upload/";
    $path = "$upload_folder/$id.jpg";
    $image = $_POST['image'];


    if(file_put_contents($path, base64_decode($image)) != false){
        echo "uploaded_success";
        exit;
    }
    else 
    {
    echo "upload_failed";
    exit;
    }
    }
    else{

    echo "image_not_in";
    exit;


}
?>
