Thinkphp5.0 框架使用模型Model添加、更新、删除数据操作详解

$res = TestUser::create([
  'name' => 'zhao liu',
  'password' => md5(123456),
  'email' => 'zhaoliu@qq.com'
]);
dump($res);

$userModel = new TestUser;
$userModel->name = 'ya ya';
$userModel->email = 'yaya@139.com';
$res = $userModel->save();
dump($res);//影响的行数
dump($userModel->id);//新纪录的id 

$userModel = new TestUser;
$userModel->name = 'hei hei';
$userModel->email = 'heihei@139.com';
$userModel->yes = '不存在字段';
$res = $userModel->allowField(true)->save();
dump($res);//影响的行数
dump($userModel->id);//新纪录的id 

$userModel = new TestUser;
$data = array(
  ['name'=>'ga ga','email'=>'gaga@sina.com'],
  ['name'=>'you you','email'=>'youyou@163.com']
);
//返回结果是个多维的数组
$res = $userModel->saveAll($data);
//如果需要得到添加的数据的每个id，需要遍历
foreach($res as $v){
  dump($v->id);
}

$res = User::update([
  'id' => 2,
  'email' => '121@qq.com'
]);
//返回修改之后model的整个对象信息
dump($res);

$res = User::update([
  'email' => '123@qq.com'
],['id'=>2]);
//返回修改之后model的整个对象信息
dump($res);

$res = User::update([
  'email' => '555@qq.com'
],function($query){
  $query->where(['id'=>2]);
});
//返回修改之后model的整个对象信息
dump($res);

$res = User::where('id','=',2)->update([
  'email'=>'666@qq.com'
]);
//返回影响的行数
dump($res);

$model = User::get(2);
$model->email = '777@qq.com';
$res = $model->save();
//返回影响的行数
dump($res);

$model = new User();
$res2 = $model->save([
  'email' => '999@qq.com'
],['id'=>2]);
//返回影响的行数
dump($res2);

$model = new User();
$res = $model->save([
  'email' => '000@qq.com'
],function($query){
  $query->where(['id'=>2]);
});
//返回影响的行数
dump($res);

$model = new User();
$res = $model->saveAll([
  ['id' => 2,'email' => '122@qq.com'],
  ['id' => 3,'email' => '123@qq.com'],
  ['id' => 4,'email' => '124@qq.com']
]);
//返回数组
dump($res);

//删除id为3的记录
$res = User::destroy(3);
//返回影响的行数
dump($res);

//删除id为3的记录
$model = User::get(3);
$res = $model->delete();
//返回影响的行数
dump($res);

//删除id为4的记录
$res = User::where('id','=',4)->delete();
//返回影响的行数
dump($res);
