Library not working

I tried to implement a library which allows me to display global data like site name, site logo, etc from the database to all the views without the necessity of passing them via controllers(which I think is time consuming).

PHP Code:

<?php

class Settings {
    //holds the CI instance
    protected $ci;

    //the array the settings will be stored as
    public $settings = array();

    //
    public function __construct()
    {
        //load CI instance
        $this->ci =& get_instance();

        //fire the method loading the data
        $this->get_settings();
    }

    public function get_settings()
    {
        $this->ci->load->model('settings_model');
        $settings = $this->ci->Settings_model->get_list();
        return $settings;
    }
}
?>

now in order to put it in my views, I've gotten to do just this:

PHP Code:

<?php echo $settings['website_name']  ?>

This is what I get, two errors, one for the undefined property:

Severity: Notice
Message: Undefined property: Store::$settings_model

and one for the function calling in null(is there a way to overwrite this?):

An uncaught Exception was encountered
Type: Error

I hope I could make myself clear.

Thanks in advance.

Your missing self or $this on your $settings array

PHP Code:

// Wrong
public function get_settings()
{
    $this->ci->load->model('settings_model');
    $settings = $this->ci->Settings_model->get_list();
    return $settings;
}

// Should be
public function get_settings()
{
    $this->ci->load->model('settings_model');
    $this->settings = $this->ci->Settings_model->get_list();
    return $this->settings;
} 


Also I think I ran into this with my Registry Class and had to make a helper with methods
to access the library methods.

So if that does not work then you will need to create a helper for the library.

Registry for CodeIgniter

What did you Try? What did you Get? What did you Expect?
