在我的用户注册页面上，我有一个表格，他们填写了他们的姓名，电子邮件等。我将把成就添加到他们需要填写的内容列表中。但是，我希望用户能够投入尽可能多的成就。稍后我将在他们的个人资料页面上显示这些成就。
这是我的注册表，如果有帮助的话。

只需在字段名称中使用括号，如下所示：
<input type="text" name="achievements[]"/>
然后使用 javascript/jquery，您可以通过为用户提供添加新成就的按钮以编程方式创建更多字段。
您可以探索的另一个选项是使用 select2 等库。它具有标记功能。
在后端，PHP 会将值转换为数组。然后 Laravel 让你从请求访问这个数组，如下所示：
public function store(Request $request)
{
$achievements = $request->get('achievements');
}
从那里，您可以像往常一样迭代并保存每个成就。
