Retrieving Chat messages between two users with Codeigniter

Your storing the chat_id and user_id so you can use those.

If chat_id is the user_id of the person that started the chat and then
the user_id is the one that they are chatting with then you can check those.

If it was me I would have a method called intiateChat() that would set this
all up for checking later.

Without seeing some of your code it is hard to see what you are trying to do.

What did you Try? What did you Get? What did you Expect?
