带前缀的Codeigniter路由模式

Question

I'm working on Codeigniter 3 route mechanism, my application is multi branch, I tried google mail url pattern like app.com/p/branch_id/controller/method/param1/param2/etc but some cases it doesn't need prefix p/branch_id/ for admin or global setting. I think my rule isn't effective.

$route['p/(:num)/(:any)'] = '$2';
$route['p/(:num)/(:any)/(:any)'] = '$2/$3';
$route['p/(:num)/(:any)/(:any)/(:any)'] = '$2/$3/$4';
$route['p/(:num)/(:any)/(:any)/(:any)/(:any)'] = '$2/$3/$4/$5';

I want achieve
/p/1/booking -> route to controller booking
/p/1/booking/create -> route to controller booking action create()
/p/1/booking/view/1 -> route to controller booking action view($id)

also same thing when user visit
/booking -> route to controller booking
/booking/create -> route to controller booking action create()
/booking/view/1 -> route to controller booking action view($id)

How i write the rule for number unknown possible of parameters, when $route['p/(:num)/(:any)'] = '$2'; just routing index controller only.

Answer 1

I am sure it will work.

$route['p/(:num)/(:any)'] = 'booking/action/$1/$2';
$route['p/(:num)/(:any)/create'] = 'booking/create/$1/$2';
$route['p/(:num)/(:any)/view/(:num)'] = 'booking/view/$1/$2/$3'; //$3 is record no.

Addition

Or if you want to make action as dynamic variable.

$route['p/(:num)/(:any)'] = 'booking/defaultAction/$1/$2';
$route['p/(:num)/(:any)/(:any)'] = 'booking/defaultAction/$1/$2'; // here in default action you need to add condition that if its create then execute create functionality. or if its view then execute view funcitonality
