Better to do it in in controller. You model can then just process the data.

I think bettet create service class for handling logic process. You can use multiple model (example save log history), and also if you want to create REST Api login, you just call this service class. You can prevent duplicating code for login. Read ADR pattern.

Hope this help

This depends on the person codeing it. If you are doing all validation in the Controller, you you need to duplicate it in every Controller. If you are doing it in the Model, you only need to do it ones.

Here's an example how it's done in Codeigniter 4:

I would also second that because if I were you, I would do that because then service class would make my work easier.Also, it is easier to prevent duplication of login code.

But then again, it really depends on you.

I agree with you
But in model,what to return to controller?
Example:
if (!'/\d+/',$mobile)
return 'invalid';

or

return -1;

What one is correct?

Thanks

They should return a Boolean false or true.

Always return true or false boolean that is the correct way of doing it.
