CodeIgniter - how to properly route?

Question

CodeIgniter

Hello!
My problem is this: I have 2 controllers main && posts , and I need to be able to access the standard controller (without specifying the controller itself) site.ru/methodname , and the rest of the controllers - specifying them in the URL site.ru/ controller/methodname

Answer 1

Write down a rule for each case.
If you need it for pages, then I advise you to register
A for everything else, it will work as it worked.

Answer 2

Below all other routes, write
Or, if you have methodname with parameters, then
$route['(:any)/(:any)'] = 'tvoy_controller/$1/$2';
