Question

我的网站正确显示网址时出现问题。我正在使用最新版本的Codeigniter。

我收到以下错误消息。我正在做一些研究，我认为我的问题是URI段，但我很困惑如何解决问题。

我的目标是让网址看起来不错（_states是我localhost上的子目录文件夹） mydomain.com/_states/dealers/Florida（此URL实际有效） mydomain.com/_states/dealers/Florida/Miami（不工作） mydomain.com/_states/dealers/Florida/Miami/8（不工作）

我还提供了routes.php和model_data.php的语法。你们将如何解决这个问题呢？提前谢谢大家。

站点控制器

   public function getDealersCity($state, $city){
     //$city = $this->uri->segment(3);
     //echo "$city";
     if(is_null($state)) return false;
     if(is_null($city)) return false;
     $this->load->model('model_data');
     $data['statecity'] = $this->model_data->get_database_by_cities($state,$city);
     $this->load->view('statecity',$data);
   }

Model_data.php函数

function get_database_by_cities($state, $city){
    $query = $this->db->get_where('states',
    array('state' => $state,
    'city' => $city)
    );
    if($query->num_rows()) return $query->result();
    return null;
}

routes.php文件

$route['default_controller'] = "site";
$route['dealers/(:any)/(:any)'] = "site/getUniqueDealerInfo/$3";
$route['dealers/(:any)/(:any)'] = "site/getDealersCity/$2";
$route['dealers/(:any)'] = "site/getCities/$1";
$route['404_override'] = '';

Answer 1

$route['dealers/(:any)/(:any)'] = "site/getUniqueDealerInfo/$3";
$route['dealers/(:any)/(:any)'] = "site/getDealersCity/$2";

路线本质上是冲突的，一条路线会覆盖其他路线。

尝试使用

$route['dealers/(:any)/(:any)'] = "site/getDealersCity/$1/$2";

没有任何功能

getUniqueDealerInfo
