如何将2个参数路由到控制器？ [英] How to route 2 parameters to a controller?

问题描述

我试图向控制器中的一个方法发送更多的参数，像这样：

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

这是我尝试过的路线：

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

方法接受2部分：

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

但我似乎得到一个404.我如何得到这个工作？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url帮助。

解决方案

您的路线方括号有问题，只需将其从{}更改为（）括号即可工作

来自

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

到

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

This seems really basic but i can't get the hang of it.

I'm trying to send more then one parameter to a method in the controller, like this :

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

This is the routings i've tried :

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

the method accepted 2 paremeters :

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

}

but i seem to get a 404. How can i get this to work? i need the view method to always accept 1 parameter and optional other parameters.

NOTE : I am including the url helper.

解决方案

you have problem with your route brackets just change it from {} to () brackets will work

from

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

to

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