如何根据id数组获取表记录？

Question

我在laravel做项目。我想根据包含列ID的数组显示所有记录。

我有数组，

$prov_Data  =  ["11","15","3","7","8","2","4"];

我希望从提供者表中获取所有记录，其中id为11,15,3,7，...连续。

当我这样做的时候，

$providerData = Provider::whereIn('id',$prov_Data)->get();

然后返回的数据为2,3,4，...按asc顺序。我想要11,15,3中的数据，...仅订购。

Answer 1

您可以使用order by field功能：

$prov_Data  =  ["11","15","3","7","8","2","4"];
$ids = implode(',', $prov_Data);
$providers = Provider::whereIn('id', $prov_Data)->orderByRaw("FIELD (id, $ids) ASC")->get();

  

仅在mysql上测试

Answer 2

$array = ["11","15","3","8","2","4","7"];
$list = implode(',', $array);
$data = Provider::whereIn('id', $array)->orderByRaw("FIELD (id, $list) ASC")->get();
return $data;
