Phpmyadmin 仅接受来自具有多个输入值的 json 数组中的一个条目

Question

谁能帮我设置正确的foreach循环以将多个输入值发送到数据库（MySQL），每当我在邮递员中执行此代码时，只有一个条目会上传到数据库中。我想一次发送多个“user_id”。

$input = json_decode(file_get_contents('php://input', true));

foreach($input->users as $user) {
    $groupId = $user->group_id;

    $groups = Group::where("group_id", $groupId)
        ->get()->first();

    foreach($input->users as $user2) {

        $groupMembers = new GroupMembers();

        $userId = $user2->user_id;
        $groupMembers->group_id = $groups->group_id;

        $users1 = Users::where("user_id", $userId)
            ->get()->first();

        $groupMembers->member_user_id = $users1->user_id;
        $response = json_decode($groupMembers, true);

        $save = $groupMembers->save();

输入json：

{
    "users" : [{
        "group_id" : "1",
        "user_id" : ["2", "3", "4"]
}]}

Answer 1

试试下面的

foreach($input->users as $user) {
          $groupId = $user->group_id;

          $groups = Group::where("group_id", $groupId)
              ->get()->first();

          foreach($user->user_id as $userId) {

              $groupMembers = new GroupMembers();

              $groupMembers->group_id = $groups->group_id;

              $users1 = Users::where("user_id", $userId)
                  ->get()->first();

              $groupMembers->member_user_id = $userId;
              $response = json_decode($groupMembers, true);

              $save = $groupMembers->save();}
        }

试试这个你正在迭代users它应该是user_id

foreach($input->users['user_id'] as $user) {
