Question

我在Codeigniter中使用hook机制。钩子的种类是post_controller_constructor。

类钩子里面有一个私有对象：

private $settings = array();

执行hook后填充此对象。如何从库CI和控制器访问$settings？

类别：

<? class LCode_module
{
    private $CI;
    private $_default_lang = "en";
    private $_sufixLangDefault = "_EN";
    private $allowedLanguages = array();

    private $_countryCurrent;
    private $countries = array();
    private $languages = array();
    private $settings = array();

    public function __construct()
    {

        $this->CI =& get_instance();

        /* Load lists */
        $this->CI->load->library('listdata');
        $this->countries['country'] = $this->CI->listdata->country;
        $this->countries['country_code'] = $this->CI->listdata->country_code;
        $this->countries['country_lang'] = $this->CI->listdata->country_lang;
        $this->languages = $this->CI->listdata->languages_sys;
    }

    public function route()
    {
      //Here I put data to $settings
    }

}

方法route是hook

中的init方法

在构造函数结束时：

/* Add object of class to GI instance */
$this->CI->LCode_module = new stdClass;
$this->CI->LCode_module->settings = &$this->settings;

我尝试在控制器中获取数据后

$CI =& get_instance();
$c = $CI->LCode_module;
var_dump($c); // NULL

使用它作为您的类，我创建了一个静态选项，您可以随时使用它：

<?php
class LCode_module
{
    private $CI;
    private $_default_lang = "en";
    private $_sufixLangDefault = "_EN";
    private $allowedLanguages = array();

    private $_countryCurrent;
    private $countries = array();
    private $languages = array();
    private $settings = array();

    private static $instance;
    private static $static_settings;

    public function __construct()
    {

        $this->CI =& get_instance();

        /* Load lists */
        $this->CI->load->library('listdata');
        $this->countries['country'] = $this->CI->listdata->country;
        $this->countries['country_code'] = $this->CI->listdata->country_code;
        $this->countries['country_lang'] = $this->CI->listdata->country_lang;
        $this->languages = $this->CI->listdata->languages_sys;
        self::$instance = &$this;
        self::$static_settings = &$this->settings;
    }

    public function route()
    {
        //Here I put data to $settings
    }

    public static function getInstance(){
        if (is_null(self::$instance)) { self::$instance = new self(); }
        return self::$instance;
    }

    public static function settings($key = NULL){
        $instance = self::getInstance();
        if(is_null($key)) return $instance::$static_settings;
        return (array_key_exists($key, $instance::$static_settings) ? $instance::$static_settings[$key] : null);
    }
}

然后你打电话

LCode_module::settings()

当您需要检索设置时

这确实意味着并行单独使用，这不是最佳实践，但它现在应该可以做到这一点，因为钩子只加载一次。我确信CI有办法执行此操作，但我现在正在填写空白。

如何从Codeigniter中的钩子获取数据？
