如何访问CodeIgniter用户定义的模型？ [英] How to access CodeIgniter user defined models?

问题描述

当我想在自定义用户定义库中的CodeIgniter中访问用户定义模型的函数时，它会抛出

在非对象上的成员函数Set_where（）

虽然我通过使用这个库内部加载模型

  $ CI =& get_instance（）; 
 
 $ CI-> load-> model（'home_model'）; 
  

我使用这个代码访问 home_model class

  $ CI-> home_model-> Set_where（film_feature ='Y'）; 
  

现在它会抛出上面的错误。

那么有人可以帮我解决这个错误吗？

解决方案现在我解决这个问题只是添加$ CI =& get_instance（）;到那个函数中，我想先获取我声明$ CI =& get_instance（）;

我的工作代码现在是..

$ CI =& get_instance（）;

$ CI-> load-> model（'home_model'）;

$ CI - > home_model-> Set_where（film_feature ='Y'）;

When I want to access a function of a user defined model in CodeIgniter inside a custom user defined library it throws

Call to a member function Set_where() on a non-object

Although I load the model by using this inside that library

$CI =& get_instance();

$CI->load->model('home_model');

And I'm using this code to access the function inside home_model class

$CI->home_model->Set_where("film_feature='Y'");

So now it throws the above error.

So could someone please help me solve this error?

解决方案

Now i fix the issue just adding $CI =& get_instance(); into that function where i want to fetch previously i declare that $CI =& get_instance(); in another function of that class for which it was not instantiated.

My working code is now..

$CI =& get_instance();

$CI->load->model('home_model');

$CI->home_model->Set_where("film_feature='Y'");
