Question

Here is my problem in codeigniter MVC.

Suppose I have 3 models: (users, email , payments).
When some one paid by some way , controller calls some method of payments model , that method could be called from other controllers too.

That method , does some database insert and update and at the end , it wants to send an email to user , it already has userid , but it needs username , email , which should get from users table and then send email.

I don’t like payments model could have access to users table and I want to get info from users model and send email using email model.

normally I call those from controller , I mean first call payments model and get the result and get users info from users model and then use email model , all in controller .

But because I need to run that model’s method in some controllers , I must repeat those lines and it is not the correct aspect in my point.

Question:
Should I call other models inside model or use other models tables inside model (in this option , if I want to reuse that model I should change it if other tables changed which is not right) , or is there any other way?

The main problem is not exactly that one it is just example of situation .
I also defined some function which does those thing and call from controllers , but it is not right too.

Answer 1

Put it all into a library.

So your controller calls the library for a “payment”, and passes some details. Your library then does ALL of the features you describe above – i.e. calls the payment model, sends the email etc etc.
