TLDR;

You need to serialize datatable into a URL-encoded string first.

Explanation

var datatable = [url, title, type, filesize, fileext,id];

Here, you're creating datatable as an array

request.open("POST", "ajax-db-files/copy_drive_file.php?" + datatable, true);

request.send("datatable=" + datatable);

Then, in these two lines, you try to concatenate the array directly to the string, which casts the array to a string by calling .join(',') on the array.

What you need is to serialize the array into URL-encoded notation. If you're using jQuery, try var datatable = $.param({ url: url, title: title, type: type, filesize: filesize, fileext: fileext, id: id]); instead.
