This article mainly introduces the method of THINKPHP to obtain the value of the primary key id when adding data. It has a certain reference value. Now I share it with you. Friends in need can refer to it.
When using ThinkPHP After adding new data, you can easily obtain the automatically growing primary key value.
$Model = D(‘Blog'); $data['name'] = 'test'; $data['title'] = '测试标题'; $data['content'] = '测试内容'; $result = $Model->add($data); if ($result){ $id = $result; // 获取数据库写入数据的主键 }else{ exit($Model->getError()); }
If the primary key of your data table is auto-growing, then the return value after the add method succeeds is the primary key value of the data. No additional acquisition required.
