Открытие модального окна по id

Из БД выводится информация о номерах.У кнопки есть id номера. Как сделать чтобы по нажатию на кнопку открывалась модальное окно этого номера?

    $(document).ready(function(){
     
      $('.open-modal').click(function(){
        $('#myModal').modal('show');
      });
     
     
    });
    
<?php
    $name=$_POST['name'];  
    $people=$_POST['people'];   
    $datearrive=$_POST['date'];
    $dateliave=$_POST['date1'];
     
?>
     
    <?php
     
    $con=mysqli_connect("localhost","root","","hotel");
    $result=mysqli_query($con,"Select * from room where  (datestart < '$datearrive' or dateend >'$dateliave') ");
     
    while ($row=mysqli_fetch_array($result)){
     
    $id_room=$row['id_room'];
    $adres=$row['name'];
    $price=$row['price'];
     
    ?>
