在codeigniter中如何從子控制器調用該方法時從父控制器中的方法獲取對子控制器的引用

Question

假設我有兩個MY_Controller的子控制器，比如Child_1 & Child_2.In MY_Controller我有兩個方法method_1 & method_2作爲

abstract class MY_Controller extends CI_Controller 
{ 
    public function __construct() 
    { 
    parent::__construct(); 
    } 

    public abstract function method_1();//children will give custom implementation 

    public function method_2() 
    { 
    some code ... 
    /*Here I want to call method_1() of the child controller that have called this method i.e. method_2* automatically */ 
    } 
} 

我從child_1 & child_2使用電話method_2（）

class Child_1 extends MY_Controller 
{ 
    public function __construct() 
    { 
    parent::__construct(); 
    } 

    public function method_1(){//custom implementation goes here} 

    public function some_method() 
    { 
    ...some code 
    $this->method_2();//call inherited method method_2() 
    } 
} 

爲child_2

Answer 1

abstract class MY_Controller extends CI_Controller 
{ 
    public function __construct() 
    { 
     parent::__construct(); 
    } 

    public abstract function method_1();//children will give custom implementation 

    public function method_2() 
    { 
    // some code ... 

    $this->method_1(); //Call the method directly it will implement the child's method 
    /*Here I want to call method_1() of the child controller that have called this method i.e. method_2* automatically */ 
    } 
}
