Question

我将Codeigniter与动态子域一起使用，但在我的控制器的每个方法中，我需要获取动态子域的帐户。我正在寻找一种方法来获取域并添加到$ data，而不是每个方法，如：

    <?php

class Dashboard extends CI_Controller {

    function index()
    {
        $subdomain_arr = explode('.', $_SERVER['HTTP_HOST'], 2);

        $subdomain_name = $subdomain_arr[0];

        $this->db->from('accounts')->where('subdomain', $subdomain_name);

        $query = $this->db->get();

        $account = $query->row();

        $data['account_id'] = $account->id;

        $data['account_name'] = $account->name;

        $this->load->view('index', $data);
    }

    function clients()
    {
        $subdomain_arr = explode('.', $_SERVER['HTTP_HOST'], 2);

        $subdomain_name = $subdomain_arr[0];

        $this->db->from('accounts')->where('subdomain', $subdomain_name);

        $query = $this->db->get();

        $account = $query->row();

        $data['account_id'] = $account->id;

        $data['account_name'] = $account->name;

        $this->load->view('clients', $data);
    }
}

在Class Constructor内执行一次，然后您可以从所有其他方法访问相同的变量。

As per docs：

“如果你需要设置一些默认值，那么构造函数很有用，或者在实例化类时运行默认进程。构造函数不能返回值，但是他们可以做一些默认工作。“

<?php class Dashboard extends CI_Controller { public $data = array(); public function __construct() { parent::__construct(); $subdomain_arr = explode('.', $_SERVER['HTTP_HOST'], 2); $subdomain_name = $subdomain_arr[0]; $this->db->from('accounts')->where('subdomain', $subdomain_name); $query = $this->db->get(); $account = $query->row(); $this->data['account_id'] = $account->id; $this->data['account_name'] = $account->name; } public function index() { $data = $this->data; // contains your values from the constructor above $data['title'] = "My Index"; // also use your $data array as normal $this->load->view('index', $data); } public function clients() { $data = $this->data; // contains your values from the constructor above $this->load->view('clients', $data); } }

注意：尽管CodeIgniter函数默认为“public”，但最佳做法是将它们声明为“public”。请参阅：Public functions vs Functions in CodeIgniter

Codeigniter子域通配符获取每个方法的帐户
