Thinkphp automatically completes the session assignment sample code in the model, and thinkphp sample code

I believe that users who have used thinkphp know that thinkphp models can complete many auxiliary functions, such as automatic verification and Automatic completion, today, during development, we encountered the function of automatically completing the task and obtaining the session value and then assigning values automatically. For details, refer to the code;

Class ArticlelModel extends Model {protected $ _ auto = array ('addtime', 'time', 1, 'function'), array ('username', 'getname ', 1, 'callback'); // This function gets the name value in the session protected function getName () {return $ _ SESSION ["name"];}

Note the difference between the function and callback of the last parameter;
Function: When a function is used, Common/common. php is automatically used to find the corresponding function;
Callback: Use the callback method defined in the current model

Thinkphp's session Shopping Cart. Thanks for the complete code examples.

<? Phpclass CartTool {private static $ ins = null; private $ items = array (); final protected function _ construct () {} final protected function _ clone () {}// obtain the instance protected static function getIns () {if (! (Self: $ ins instanceof self) {self: $ ins = new self ();} return self ::$ ins ;} // put the singleton object of the shopping cart in the session public static function getCart () {if (! Isset ($ _ SESSION ['cart']) |! ($ _ SESSION ['cart'] instanceof self) {$ _ SESSION ['cart'] = self: getIns ();} return $ _ SESSION ['cart'];} /* Add item param int $ id item primary key param string $ name item name param float $ item price param int $ num Number of purchased items */public function addItem ($ id, $ name, $ price, $ brand, $ thumb, $ num = 1) {if ($ this-> hasItem ($ id) {// if the item already exists, add the number $ this-> incNum ($ id, $ num); return;} $ item = array (); $ item ['id'] = $ id; $ item ['name'] = $ name; $ Item ['price'] = $ price; $ item ['brand'] = $ brand; $ item ['thumb'] = $ thumb; $ item ['num'] = $ num; $ this-> items [$ id] = $ item; return $ this-> items [$ id];} /* modify the number of items in the shopping cart, param int $ id, item primary key, param int $ num, change the quantity of a product to $ num */public function modNum ($ id, $ num = 1) {if (! $ This-> hasItem ($ id) {r ...... remaining full text>
