如何判断一个更新操作是否成功
$Model = D('Blog');<br> $data['id'] = 10;<br> $data['name'] = 'update name';<br> $result = $Model->save($data);<br> if ( false !== $result ){<br>     $this->success('更新成功!');<br> }else{<br>     $this->error('更新失败!');<br> }需要用 !== false 来判断更新是否成功,因为save方法返回值是更新操作影响的记录数,有可能影响的记录数为0,但却更新成功的。
