I have a series of classes written in php and passing around using session variables. Everything was working fine until I had to embed my inventory search pages in to different domains using iframes. even with iframe it works except IE. In IE+iframe doesn't pass the session variables correctly so I had to serialize my objects and save in to a tmp file first, and when i need the object in different page I unserialize the object from the tmp file. Even this is working fine, except when inheritance links are broken of the objects. I know that I have to include all the class definitions in to the file where I unserialize the objects, but still it won't keep the inheritances. I just include the class definition by using require_once('class.php'); .
Any ideas ?????
