There’s so many tricks to this. We can use mod_rewrite on some specific pattern, or force our CI to use one Master-Controller, or rewrite CI router mechanism.
But I am going to use the easiest one, only changing CI router.php config
At first I use this on CI routes.php
$route['(:any)'] = "incidents/detail_shortened/$1";
As expected, It’s kind of working, but it makes all of my controller inaccessible, that is because any ‘/controllername/parameter/’ format will match with ‘(:any)’ and will be redirected to our ‘incidents/detail_shortened/’.
To stop controllers redirected by the CI router, I have to explicitly define all of my controllers on the routes.php first (since it’s handled in sequence)
This is the code for that:
$route['default_controller'] = "welcome"; $route['404_override'] = 'help/show404'; // define all 'normal' possible routing path $route['callbacks'] = 'callbacks'; $route['callbacks/(:any)'] = 'callbacks/$1'; $route['faqs'] = 'faqs'; $route['faqs/(:any)'] = 'faqs/$1'; $route['help'] = 'help'; $route['help/(:any)'] = 'help/$1'; $route['welcome'] = 'welcome'; $route['welcome/(:any)'] = 'welcome/$1'; // the last resort (dynamic) $route['(:any)'] = "incidents/detail_shortened/$1";
And now it works 🙂 all controller will he handled normally, and my shortened dynamic url will be properly
handled by my `incidents` controller.
This applies to CodeIgniter 2.0 (i am not sure whether it works for CI < 2.0)
You can also apply this scenario for your SEO friendly dynamic URL (e.g. http://yoursite.com/content-title-that-is-seo-friendly)
