How to modify only one value in thinkphp?
Database operation: modify a piece of data (thinkPHP)
The first method: the database contains an automatically growing field ID, and the ID is used as the where condition
<?php class UserAction extends Action{ public function updateUser(){ $user = M('Userinfo'); //实例化Model $data = array('ID'=>5,'username'=>'王美人','email'=>'meiren@163.com');//$data中包含有自动增长字段uid $res = $user->save($data);//调用Model下的save()函数进行数据的修改 var_dump($res); } } ?>
Second method: If there is no automatic growth of field ID in the database, you need to add where conditions
<?php class UserAction extends Action{ public function updateUser(){ $user = M('userinfo');//实例化Model $data = array('username'=>'王美人','email'=>'mei@163.com');//$data中没有自动增长字段uid $res = $user->where('ID=5')->save($data);//需要增加where条件。调用Model下的save()函数进行数据的修改 var_dump($res);//返回影响的行数 } } ?>
