Codeigniter: easiest way to use variables between models and controllers, models and models, controllers and controllers
You cannot access a variable if it's in a seperate file, instead you should set it in your class.
class User_model extends Model { // Declare the foo variable public $foo = ""; function blah() { // You can set variable foo this way from any controller/model that includes this model $this->foo = "dog"; // You can access variable foo this way echo $this->foo; }}
