如何将2个参数路由到控制器？

Question

这看起来非常基本,但我无法理解它.

我正在尝试向控制器中的方法发送多个参数,如下所示:

http://localhost/ci/index.php/subjects/3/state

这是我尝试过的路线:

$route['subjects/(:num)'] = 'subjects/view/$1';
$route['subjects/(:num)/{:any}'] = 'subjects/view/$1/$2';

方法接受2个参数:

public function view($slug, $id = null){

}

但我似乎得到了404.我怎么能让这个工作？我需要view方法总是接受1个参数和可选的其他参数.

注意:我包括网址助手.

Answer 1

您的路线支架有问题,只需将其从{}更改为()括号即可

从

$route['subjects/(:num)/{:any}'] = 'subjects/view/$1/$2';

至

$route['subjects/(:num)/(:any)'] = 'subjects/view/$1/$2';

Answer 2

始终保持您的路由规则

喜欢

$route['subjects/(:num)/(:any)/(:any)/(:any)'] = 'subjects/view/$1/$2/$3/$4';
$route['subjects/(:num)/(:any)/(:any)'] = 'subjects/view/$1/$2/$3';
$route['subjects/(:num)/(:any)'] = 'subjects/view/$1/$2';

始终遵循此模式进行路由

如果你这样添加

$route['subjects/(:num)/(:any)'] = 'subjects/view/$1/$2';
$route['subjects/(:num)/(:any)/(:any)/(:any)'] = 'subjects/view/$1/$2/$3/$4';
$route['subjects/(:num)/(:any)/(:any)'] = 'subjects/view/$1/$2/$3';

然后总是第一个条件每次都是真的.
