How to access model to query database from a helper function?
You will not be able to use $this to access your CI instance in a helper, but CI has a way to do this -
First, you need a reference to your CI instance:
$CI =& get_instance();Then, if you need to load the model you can do it like so:
$CI->load->model('model_name');And finally call any function in your model like this:
$CI->model_name->function_name();Basically, use $CI instead of $this. Hope that helps.
It's not that much code repetition. I'd suggest this approach:
function __construct(){ parent::Controller(); if ($this->auth->is_logged_in() !== TRUE) // "auth" is the authentication library { redirect('login'); }}
