laravel中的CRUD操作中,通过对代表数据表中row的model对象操作,来更新数据库表。 对于创建新的row的操作,有两种功能上相同的方法: 1.create; $user= User::create(array('email => 'xx@yy.zz','password'=>'mypassword')); 2.new and save $user=newUser;$user->email = 'xx@yy.zz';$user->passwo...
$user = new User; $user->user_no = ‘100’; $user->user_name = ‘test’; $user->save(); 批量赋值(可以批量赋值的字段必须在model文件中protected $fillable=[]数组中) $user = User::create([ ‘user_name’ => ‘Flight 10’, ‘user_no’=>‘002’ ]); 3:更新 $user = User::find...
