How to get and write to the database all the data from the dynamic form field?

Question

HTML

There is a standard form, the Phone field is dynamic, you can add several fields with the same name.
It is not possible to Send all the data of this field to the database and then receive it.
Only the last record of this field is sent to the database.
view:

<form method="POST" action="{{route('posts.store')}}">
            {{ csrf_field() }}
            <button type="submit" class="btn btn-success mb-3">Добавить запись</button>

            <div class="form-group">
                <label for="post-name">Имя</label>
                <input type="text" name="name" value="{{old('name')}}" class="form-control" id="post-name">
            </div>
            <div class="form-group">
                <label for="post-surname">Фамилия</label>
                <input class="form-control" type="text" name="surname" value="{{old('surname')}}" id="post-surname">

Answer 1

You have multiple fields with the same name 'phone'. Accordingly, when parsing the query string, PHP stores only the last one in $_POST['phone'] .
You can pass fields as an array by specifying name='phone[]'.
