Question

我能够在表格中显示数据行。我想在每个表的末尾放一个按钮，以便我能够删除/编辑该特定行。所以这是

$found_row = 0;
$result = mysqli_query($conn,"SELECT * from TICKET INNER JOIN CUSTOMER ON TICKET.CUSTOMER_ID=CUSTOMER.CUSTOMER_ID");

echo "<table>"; // start a table tag in the HTML
echo "<tr>
        <th>Ticket ID</th>
        <th>Customer ID</th>
        <th>Name</th>
        <th>Address</th>
        <th>Phone</th>
        <th>Email</th>
        <th>Pickup Date</th>
        <th>Pickup Time</th>
        <th>Delivery Date</th>
        <th>Delivery Time</th>
        <th>Payment Mode</th>
        <th>Payment Status</th>
        <th>Ticket Status</th>
        <th>EDIT STATUS</th>
        </tr>";

    while($row = mysqli_fetch_array($result)){   //Creates a loop to loop through results
    $found_row = true;
    $wow = $row['TICKET_ID'];
    echo " <tr>
            <td>".$row['TICKET_ID']."</td> 
            <td>".$row['CUSTOMER_ID']."</td>
            <td>".$row['CUSTOMER_NAME']."</td>
            <td>".$row['CUSTOMER_ADDRESS']."</td>
            <td>".$row['CUSTOMER_PHONE']."</td>
            <td>".$row['CUSTOMER_EMAIL']."</td>
            <td>".$row['TICKET_PICKUP']."</td>
            <td>".$row['TICKET_PTIME']."</td>
            <td>".$row['TICKET_DELIVERY']."</td>
            <td>".$row['TICKET_DTIME']."</td>
            <td>".$row['TICKET_PAYMENT']."</td>
            <td>".$row['PAYMENT_STATUS']."</td>
            <td>".$row['TICKET_STATUS']."</td>
            <td>".("<a href='cancelticket1.php?id=$wow'>Delete</a>")."</td></tr>";

    }
    if ($found_row == false) {
            echo "No Ticket Submitted";
        }

    echo "</table>";

所以现在我能够为每行重定向具有ticket_id返回值的页面。例如，url为/cancelticket1.php?id=1001。并在页面cancelticket1.php中，这是代码：

$cancelticket=$_GET['$wow'];
$sql = "DELETE FROM TICKET WHERE TICKET_ID=$cancelticket";
if ($conn->query($sql) === TRUE) {
echo "Ticket Has Been Deleted";
} else {
echo "Error: " . $sql . "<br>" . $conn->error;
}

从这里我很难理解如何检索该ticket_id，并且我不断收到错误消息但是我试过了。请帮我。
