Sending ID of a PHP row with HTML button

I have a site that uses google maps API to add markers to a map and also add details for these markers and save them to a PHP database. These saved markers then can be clicked and they bring up an info window displaying thee specific data for that marker.

The PHP/HTML that displays the info window is:

$result = mysqli_query($con, "SELECT * FROM events");

while($row = mysqli_fetch_array($result))
{
echo "<div class='event-details' id='event-details' style='display: none ''>";
echo "<h3>Event Details</h3>";
echo "<table class='table'>";
echo "<tr><th>Event Name: </th><td>" . $row . "</td></tr>";
echo "<tr><th>Event Date: </th><td>" . $row . "</td></tr>";
echo "<tr><th>Event Type: </th><td>" . $row . "</td></tr>";
echo "<tr><th>Event Details: </th><td>" . $row . "</td></tr>";
echo"</table>";
echo "<td><a href='details.php?id=".$row."' class='btn btn-warning btn-sm'>View</a></td></div>";
}

The JS that displays this info with each marker is:

var eventList = $("#event-details").clone().show();

// Display Event details on marker click
google.maps.event.addListener(event_markers, "click", function () {
infowindow.setContent(eventList[0]);
infowindow.open(map, event_markers);
map.setCenter(marker.getPosition());
map.setZoom(10);
});

Each item in the DB has a unique ID. I want to use this ID variable so that I can send it to other pages so the info can be viewed or that row can be deleted from the DB using its ID.

As of now, there are 3 different items in the 'events' DB, with ID's being, 6, 7, and 8. Now when I inspect element on each of the markers, they all say that

<a href="details.php?id=6" class="btn btn-warning btn-sm">View</a>

But I want them to display their own ID, not just the first one. So when I click the marker that has an ID of 8 in the DB, it should say "details.php?id=8", and NOT "details.php?id=6"
