Help with saving XML files with PHP to a server

Hi All,

I had serialize the object and trying to post it to my php, Unity3d shows url malformed whenever I click save button.

_GameSaveLoad.cs

[CODE]

using UnityEngine; using System.Collections; using System.Xml; using System.Xml.XPath; using System.Xml.Serialization; using System.IO; using System.Text;

 string url;
 byte[] bytes;

 //so we setup our initial values for our local members
