Codeigniter - 获得一个uri param

Question

I am looking to pass one parameter to my function. Page is sub.mainsite.com/profile/change-password

The profile is the controller and change-password is the function within it. Now I want to pass change-password/first if it is the users first time logging in so the system can redirect them to the home page instead of the profile page.

$uri_params = I_WANT_TO_SEE_IF_FIRST_IS_SET;

Answer 1

Simply do this way .

$uri = $this->uri->segment(3)
This will retrieve change-password $uri_params = $uri .'/first';
