Question

I am trying to load the cookie helper in my pre_controller hook for a ‘remember me’ function on our site. I thought that creating an instance of the CI object with $ci =& get_instance(); would allow me to access to loading helpers but this is not the case.

Thoughts?

 $ci =& get_instance();
 $ci->load->helper('cookie');
 // does not load

Answer 1

The pre_controller hook executes before the super object has been fully constructed, so get_instance() can’t work – the static object it returns a reference to hasn’t yet been initialized.

Consider using the post_controller_constructor hook instead; your controller’s constructor will have executed, and the CI super object will be available for use.
