routes - CakePHP 1.3 Routing problem -

it can't correct route following:

router::connect('/ctl/act/subact/:mode/:sort'        , array('controller' => 'ctl', 'action' => 'act_subact', 'mode' => null , 'sort' => null)); 

--

$html->link('go',array('controller'=>'ctl','action'=>'act_subact')) 

--

<a href="/ctl/act_subact/">go</a> 

how can do? env:cakephp 1.3.6 php5.2.5 on apache2

the route /ctl/act/subact/:mode/:sort means there must :mode , :sort parameter. route not match url /ctl/act/subact/. if there optional parameters, need denote asterisk: /ctl/act/subact/*. route match urls /ctl/act/subact/, /ctl/act/subact/foo , /ctl/act/subact/foo/bar.

if need these optional parameters named parameters, you'll need create several routes each possible "length":

router::connect('/ctl/act/subact/:mode/:sort', array('controller' => 'ctl', 'action' => 'act_subact', 'mode' => null, 'sort' => null)); router::connect('/ctl/act/subact/:mode', array('controller' => 'ctl', 'action' => 'act_subact', 'mode' => null)); router::connect('/ctl/act/subact/', array('controller' => 'ctl', 'action' => 'act_subact'));
