thinkphp automatically completes session assignment sample code in the model

I believe that users who have used thinkphp know that the thinkphp model can complete many auxiliary functions, such as automatic verification, automatic completion, etc. Today, during development, I encountered the function of obtaining the session value and then automatically assigning the value in the automatic completion. Please refer to the code for details;

class ArticlelModel extends Model {
 
protected $_auto = array (
array('addtime','time',1,'function'),
array('username','getName',1,'callback')
);
 
//这个函数获取session里的name值
protected function getName(){
return $_SESSION["name"];
}
}

Here you need to pay attention to the difference between the last parameter function and callback;
function: when using a function, it will automatically go to Common/common.php to find the corresponding function;
callback: use the callback method defined in the current model
