数据库中数据表类型Innodb
controller 层文件
$m = M();
???????????$m->startTrans();
???????????$shop = $m->query(‘SELECT * FROM `think_shop` WHERE id=‘.$custom[‘shop_id‘].‘ FOR UPDATE‘);
???????????$shop = $shop[‘0‘];
???????????$ret1 = D(‘Transaction‘)->goodsNum(参数1,参数2, $m);
???????????if(!$ret1) {
??????????????? $m->rollback();
???????????} else {
??????????????? $m->commit();
???????????}
model 层文件
public function goodsNum(参数1,参数2, $m) {
操作....
//$ret1 = $m->execute("UPDATE `think_shop_goods` SET `stock` = stock-".$goodsNum[$key]." WHERE goods_id=".$goodsId." AND shop_id = ".$shop[‘id‘]);
//判断结果 返回true 或者 false
if(! $ret1) {
??????????????? return false;
???????????} else {
??????? return true;
}
???}
注意model层不需commit和rollback
