When you call the test2 method of a subclass, You do not automatically call the constructor of the parent class. To call the test method of the subclass, you must automatically call the constructor of the parent class.

Use Home \ Common \ BBaseController;
Class IndexController extends BBaseController {

Public function _ construct () {parent ::__ construct ();} public function test () {echo "automatically calls the constructor of the parent class";} public function test2 () {echo "manual control does not call the constructor of the parent class ";}

}

Namespace Home \ Common;
Use Think \ Controller;
Class BBaseController extends Controller {

Public static $ login = true; // public function _ construct () {parent :__ construct (); $ this-> initialize ();}

Public function initialize () {if (! Session ("admin_home_user") {$ this-> error ("You have not logged on, please log on", "/Home/login", '3 ');}}

}
