Thinkphp 跨模型实现事务回滚

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
