Hooks 在 CodeIgniter 2.X 中不起作用

Question

我已经在 config.php 中启用了钩子，

$config['enable_hooks'] = TRUE;

这里是 hook.php

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

| Hooks
| -------------------------------------------------------------------------
| This file lets you define "hooks" to extend CI without hacking the core
| files.  Please see the user guide for info:
|
|   http://codeigniter.com/user_guide/general/hooks.html
|
*/

$hook['post_controller_constructor'] = array(
    'class' => 'Authorization',
    'function' => 'authorize',
    'filename' => 'authorization.php',
    'file_path' => 'hooks'
);

/* End of file hooks.php */
/* Location: ./application/config/hooks.php */

，这里是 application/hooks/ 下的authorization.php 文件，

<?php 


    class Authorization {

        private $ci;

        function __construct()
        {
            parent::__construct();
            $this->ci = get_instance();
        }

        function authorize()
        {
            echo 'This should be outputed';
        }

    }

?>

但它不起作用。没有人知道为什么吗？

Answer 1

我正在使用 Codigniter 2.1 并且它可以工作..但是我的钩子文件被称为“MainLoader”并且像这样开始：

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

class MainLoader {

  public function mainLoader()
  {

      $CI =& get_instance();

      echo 'This should be outputed';

      //Whatever you want to do here

  }

我希望它有帮助:-)

我认为您错过了数组变量旁边的 [] 。
在您的代码中写道：

$hook['post_controller_constructor'] = array(
    'class' => 'Authorization',
    'function' => 'authorize',
    'filename' => 'authorization.php',
    'file_path' => 'hooks'
);

我认为应该是这样的：

$hook['post_controller_constructor'][] = array(
    'class' => 'Authorization',
    'function' => 'authorize',
    'filename' => 'authorization.php',
    'file_path' => 'hooks'
);

注意 $hook['post_controller_constructor'] 变量旁边的 [] 。

希望这有帮助。谢谢..
