CodeIgniter custom library error: Call to a member function on a non-object

Question

I'm trying to build a custom library which will contain functions that would be available through the whole site. Inside `/application/libraries` I've made a new file `CustomFuncts`: ``` ci =& get_instance(); } /** * @brief checkCookie * * Checks for a previous cookie, and if exists: * @li Loads user details to CI Session object. * @li Redirects to the corresponding page. * */ public function verificaCookie(){ $this->ci->load->view('index'); } } /* End of file CommonFuncts.php */ /* Location: ./application/libraries/CommonFuncts.php */ ``` And in controller `welcome.php`: ```

Accepted Answer

If your library extends `CI_Controller`. That means that you are actually extending the functionality of the controllers. Instead declare your library like this:

```
class CommonFuncts { }
```

You don't need to inherit from `CI_Controller`, since you are writing a library not a controller and a library is not part of the MVC model. It's single class which extends the features of the framework, fixes a common issue or has a functionality used by many controllers.

To access it's methods use:

```
$this->load->library('CommonFuncts');
$this->commonfuncts->verificaCookie();
```

If you want to simplify the name with which you call the library use:

```
// The second argument is the optional configuration passed to the library
// The third argument is the name with which you would like to access it
$this->load->library('CommonFuncts', '', 'common');
$this->common->verificaCookie(); //  /\ = configuration
//     /\/\/\ = name
```
