CI中在瞧图层直接调用library

CI中在视图层直接调用library

? 在CodeIgniter中,一般来说,是要在控制层中调用library的,但假如要在
视图层调用library的话,比如:
?? $this->load->library(‘some_library’);

这样调用,按道理说是违反MVC的,但假如要确实调用的话,上面调用也是错误的,会
显示:
?? PHP Fatal error:? Call to a member function some_library_function() on a non-object in …….php file.
?? 而要如下方式调用:
?? $ci_obj = & get_instance();
$ci_obj->load->library('some_library');
$ci_obj->some_library->some_library_function();


? 或者写成方法:
? function load_library($library_name) {

$ci = & get_instance();
$ci->load->library($library_name);
return $ci->$library_name;

}
