忽略uri细分

Question

我需要能够将第一个uri段“admin”添加到我的列表忽略列表中，但它无法正常工作。它适用于uri segment 2＆amp; 3但不是'admin'是uri段1。

如何让它忽略uri segment 1'admin'以及

我使用codeigniter 3和HMVC

$route['admin'] = "admin/common/login/index";

核心/ Controller.php这样

<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');

class Controller extends MX_Controller {

public function __construct() {
    parent::__construct();

    $url = $this->uri->segment(2).'/'.$this->uri->segment(3);

    if (isset($url)) {
        $route = '';

        $part = explode('/', $url);

        if (isset($part[0])) {
            $route .= $part[0];
        }

        if (isset($part[1])) {
            $route .= '/' . $part[1];
        }

        $ignore = array(
            'common/dashboard',
            'common/login',  // renamed admin in routes.php
            'common/logout',
            'common/forgotten',
            'common/reset',
            'error/not_found',
            'error/permission'
        );

        if (!in_array($route, $ignore, $this->uri->segment(1)) && !$this->permission()) {
            redirect('admin/permission');
        }
    }
}

public function permission() {
    $path = $this->uri->segment(2).'/'.$this->uri->segment(3);
    return in_array($path, $this->session->userdata('access'));
}

}
