custom library with parameters : problem

$this will only contain objects that are loaded before the view is loaded.
If you want to load classes in a view you must do it like this:

PHP Code:

$ci =& get_instance();
$ci->load->library('yourlibrary');
$ci->yourlibrary->get(); 


This is one of the reasons using $this in views should be avoided. Pass everything you need in your view via the data argument when loading a view
