Question

我想在控制器的特定功能之后在codeigniter中使用hook。根据文档，它将引导钩子在所有控制器之后运行。但我想让我的钩子在特定功能之后运行。

请帮助一些例子...... 谢谢

如果你想设置几个功能使用挂钩，你可以直接添加它们，
如果大多数函数使用hook，则设置hook.And判断钩子中的特定函数这是我的例子：

配置/ config.php中

$config['enable_hooks'] = TRUE;

配置/ hook.php

// I set the hook type to 'post_system', after rendering page hook execute.
$hook['post_system'] = array(
    'class'    => 'HookClass',
    'function' => 'abc',
    'filename' => 'hookClass.php',
    'filepath' => 'hooks',
    'params'   => ''
    );

钩/ hookClass.php

class HookClass{
    private $particularFunction;
    private $CI;

    function __construct(){
        $this->particularFunction=array('f1','f2');//set particular function name
        $this->CI=& get_instance();                //important!get CI class
    }

    function abc(){
        //if method not in particular function array,execute hook
        if(!in_array($this->CI->router->method, $this->particularFunction))){
            //$this->CI->router->method gets the executing method name
            //execute hooks
        }
    }
}

example_controller.php

class Example_controller extends CI_controller{
    function f1(){
        //f1 function,and hooks will not execute.
    }
    function d1(){
        //d1 function and hooks will execute 
    }
}

麻烦在codeigniter中使用hook
