controller

public function store(Request $request)
{
    $member = $request->input('GroupID');

    foreach($member as $value) {
        $storeInfo = new notice();
        $storeInfo->GroupID = $request->input('GroupID');
        $storeInfo->Notice = $request->input('Notice');
        $storeInfo->save();
    }

    return redirect('/notice');
}

Answer 1

我想你得到这个错误的原因是因为：

$storeInfo->GroupID = $request->input('GroupID');

$request->input('GroupID')将返回一个数组（name='GroupID[]'），而不是个人id。

由于您已经循环遍历组ID，因此您可以使用GroupId的值：

public function store(Request $request)
{
    foreach ($request->input('GroupID') as $groupId) {
        $storeInfo = new notice();
        $storeInfo->GroupID = $groupId; //<--here
        $storeInfo->Notice = $request->input('Notice');
        $storeInfo->save();
    }

    return redirect('notice');
}

Answer 2

尝试更改控制器逻辑

 public function store(Request $request)
{
    //
    $member=$request->input('GroupID');
    foreach($member as $value){
        $storeInfo = new notice();
        $storeInfo->GroupID = $value;
        $storeInfo->Notice = $request->input('Notice');
        $storeInfo->save();
    }

        return redirect('/notice');
}
