How to add multyply record to database

Question

I don't know how to add a double record to db.

I have form with double same row content. I would like to add a dynamic line in the next step using js but at this point I used double html to validate it.

<form class="formAddCoupon" action="/?dashboard=coupon" method="post">
                    <div class="windowEvents">
                        <div class="row">
                            <input type="text" class="teamInput" name="team1">
                            <input type="text" class="teamInput" name="team2">
                            <select name="score" id="selectOptions">
                                <option value="Liczba bramek">Liczba bramek</option>

    }

When i send a form only one record is added to database. I know why, but what do i have to do to get a double record ?
