How to Process Params of a Route Callback Function?

For the second problem, try setting a default value for $b

PHP Code:

$route['controller/(:any)/(:any)'] = function ($a, $b = '') {
    $r = 'controller/';
    switch ($a) {
        case 'specific_method':
             $r .= $a.'/'.$b;
            break;
        case 'specific_param_for_index':
             $r .= 'index/'.$a.'/'.$b;
            break;
    }
    return $r;
}; 


The code which adds 'index' to the URI segments if it isn't found appears to be executed after the callback.

Once the callback returns a string, the Router attempts to resolve the string to a controller/method/parameters.

Another option might be simpler, though. You should be able to do something like this:

PHP Code:

$route['controller/specific_method/(:any)'] = 'controller/specific_method/$1';
$route['controller/(:any)/(:any)'] = 'controller/index/$1/$2';
$route['controller/(:any)'] = 'controller/index/$1'; 


As long as the 'controller/specific_method' route is defined first, it should be resolved before the 'controller/(:any)' routes.
