thinkphp3.2.3的excel导入数据事务处理代码片段
1.功能商品名称不能重复,包含excel里面不能重复,同时也不能和已经导入的商品名字重复。(没有通过数据库唯一约束实现)
2.循环里面一条一条处理,一旦有一条数据处理失败则回滚,都成功才会最终提交。(mysql数据库引擎需要是innodb)
3.如果多行数据有问题,失败问题原因都会展示。(错误累计展示,方便对excel修改,再次导入)
代码如下:
private function save_import_new($data) { $basekeynum = $_SESSION["accountinfo"]["basekeynum"]; if (empty($data)) { $rt["sta"] = 0; $rt["msg"] = "导入为空"; echo json_encode($rt); die; } $error_flag="0"; $error_msg=""; foreach ($data as $key => $value) { $goods_id =$value["A"]; $goods_name =trim($value["B"]); $cate_name =trim($value["C"]); $goods_img = $value["D"]; $goods_des = $value["E"]; $goods_sort = $value["F"]; $goods_money = $value["G"]; $is_show = $value["H"]; if($goods_name=='') { $error_flag=1; $error_msg.= "第" . $key . "行商品名称为空!<br/>"; } if($cate_name=='') { $error_flag=1; $error_msg.= "第" . $key . "行分类名称为空!<br/>"; } $goodsinfo = M("goods")->where("goods_name='$goods_name' and basekeynum='$basekeynum' ")->find(); if (!empty($goodsinfo)) { $error_flag=1; $error_msg.= "第" . $key . "行商品名称和系统里面重复<br/>"; } } if($error_flag=='1') { $rt["sta"] = 0; $rt["msg"] = $error_msg; echo json_encode($rt); die; } //开启事务处理机制 $flag = true; $Model = M(); $Model->startTrans(); foreach ($data as $key => $value) { $goods_id =$value["A"]; $goods_name =trim($value["B"]); $cate_name =trim($value["C"]); $goods_img = $value["D"]; $goods_des = $value["E"]; $goods_sort = $value["F"]; $goods_money = $value["G"]; $is_show = $value["H"]; $goodsinfo = $Model->table('zs_goods')->where("goods_name='$goods_name' and basekeynum='$basekeynum' ")->find(); if (!empty($goodsinfo)) { $flag = false; $error_msg.= "第" . $key . "行商品名称(".$goods_name.")和excel里面其他行重复<br/>"; } //先查询分类是否存在,不存在则新增 $cate_info =$Model->table('zs_goods_cate')->where("cate_name='$cate_name' and basekeynum='$basekeynum' ")->find(); if (!empty($cate_info)) { $cate_id=$cate_info['cate_id']; } else { //新增 $addcate['cate_name']=$cate_name; $addcate['cate_sort']=0; $addcate['add_time']=time(); $addcate['status']=1; $addcate['basekeynum']=$basekeynum; $cate_id=$Model->table('zs_goods_cate')->add( $addcate); if(!$cate_id) { $flag = false; $error_msg.= "第" . $key . "行分类名称".$cate_name."新增失败<br/>"; } } //新增商品 $add["goods_name"] = $goods_name; $add["cate_id"] = $cate_id; $add["goods_img"] = $goods_img; $add["goods_des"] = $goods_des; $add["goods_sort"] = $goods_sort; $add["goods_money"] = $goods_money; $add["is_show"] = $is_show; $add["goods_add_time"] = time(); $add["basekeynum"] = $basekeynum; $goods_id=$Model->table('zs_goods')->add($add); if(!$goods_id) { $flag = false; $error_msg.= "第" . $key . "行商品名称".$goods_name."新增失败<br/>"; } } if($flag==true) { $Model->commit(); $rt["sta"] = 1; $rt["msg"] = "导入成功"; echo json_encode($rt); die; } else { $Model->rollback(); $rt["sta"] = 0; $rt["msg"] = "导入失败,失败原因".$error_msg; echo json_encode($rt); die; } }
