ci3 use controller function in "main" view. - Goddard - 02-11-2020
I have a main view and I would like to use a controller method in it. Is that not possible?
The controller method is an extension of CI_Controller..a MY_Controller class.
Thanks

Not sure I understand your question, but as a rule functions (such as those found in a controller) should not be executed in a view. Following the "rules" of MVC, the result of any function required in a view should be obtained in the controller and the results passed to the view.
Forgive me if I have misunderstood your question.

We can use controller methods from code igniter inside a view, but in the case of the "main template" file in ci3 you cannot use a controller method? At least in my testing it wasn't working.
If we are checking permissions to see if a user can view a link for example the controller has a $this->checkPermission()...it makes sense to call a function like this to verify the users permissions, no?

Using only PHP there is no way to stop a link's action after it is clicked. When a link is clicked the browser goes immediately to the URL. The URL is represented by a controller and it is that controller which checks permissions. The user will get one view or another, or be redirected somewhere else depending on the permissions granted.
But a better use of checkPermission() might be to not show users links to pages they don't have permission to see.

Personally I would pass down for e.g. Article and use $article->canEdit() for displaying the edit button in the view. And letting the class itself handle what you can do with it.

Yeah I do like that method. So then when my model is initialized it would be assigning the permissions for this user?

That or you need to pass down a variable that's true/false depending on your checks.
