php - 输出2时如何从第一行获取数据

Question

如图所示，我有 2 个立即付款按钮，但是如何在按下按钮时从行获取数据并输出到模式中。如果我这样做 $row[' paymentAmount'] 它每次都会显示最后一行。如何将按钮与行关联起来，以便它在模式中显示正确的金额？

<div class='payment_container'>
<div class='row col-md-12 custyle'>
    <table class='table table-striped custab'>
        <thead>
            <tr>
                <th>ID</th>
                <th>Name</th>
                <th>Ammount</th>
                <th>Due Date</th><?php if ($_SESSION['renterID'] == 0) {
                                                            echo "<th class='text-center'>Paid?</th>";
                                                          } else {
                                                          echo "<th class='text-center'>Action</th>";
                                                          }
                                                          ?>
            </tr>
        </thead><?php
                                        include_once 'includes/database.php';
                                        if ($_SESSION['renterID'] == 0){
                                          $sql = "SELECT firstName, lastName, paymentID, paymentAmount, paymentDate, paymentPaid FROM renter, payment WHERE renter.renterID = payment.renterID ORDER BY paymentDate ASC";

                                        }
                                        $result = mysqli_query($conn, $sql);

                                        }
                                        ?>
    </table>
</div>

谢谢!抱歉，如果这没有意义，因为我对 PHP 很陌生并且正在尝试学习。

只需使用单击按钮的行的 ID。
