在CodeIgniter中的模型中加载库 [英] Load a library in a model in CodeIgniter

问题描述

为什么我的模型不加载加密库？

  class User_model extends Model {
 
 function User_model（）{
 parent :: Model（）; 
 $ this-> check_login（）; 
} 
 
 function check_login（）{
 $ this-> load-> library（'encrypt'）; 
 $ email = $ this-> encrypt-> decode（$ email）; 
 .... 
} 
} 
  

PHP错误：调用成员函数decode（）on一个非对象在第X行 - 其中X是$ this-> encrypt-> decode（$ email）;

=

$ <$ p


$ b < h2_lin>解决方案

我是从构造函数内调用check_login，这是造成问题的原因。

解决方法是调用 $ this-> _assign_libraries（）;

$ b

Why won't my model load the encryption library?

class User_model extends Model {

  function User_model() {
    parent::Model();
    $this->check_login();
  }

  function check_login() {
    $this->load->library('encrypt');
    $email = $this->encrypt->decode($email);
    ....
  }
}

This giving me a PHP error: Call to a member function decode() on a non-object on line X -- where X is the $this->encrypt->decode($email); line?

Edited to show that the problem was that check_login was called from the constructor

解决方案

I was calling check_login from within the constructor, and that was causing the problems.

The solution is to call $this->_assign_libraries(); right after loading a library in a constructor.
