output of button does not displayed

[sashavalentina]

I want to output the data and also the buttons in my php codes. But i do not know why the buttons does not output as coded. Can anyone let me know where did my codes go wrong? I've been searching it but i cant't find the problem. Thanks in advance.

<?php
   if(isset($_POST['invoice_details'])) {
          $discountsql = "INSERT INTO `invoice_price` (`order_id`) VALUES ('.$order_id.') ";
          $conn->query($discountsql);
        }
        ?>
         <?php
          $sql2 = " SELECT order_id FROM ordered_items GROUP BY order_id WHERE order_id = '".$row[order_id]."'  ";
                      $query2 = $conn -> query($sql2);
                      while ($row2 = $query2 -> fetch_assoc()) {
        
        ?>
        
    <div class="col-12 form-group">
         <p> <?php echo $row2['order_id']; ?></p>
        <p class="text-success"  pointer-events="none" style="font-weight: bold; font-size: 25px; text-align:center;  ">Your order is confirmed !</p>
      <a href="order-list.php">
        <input class="btn btn-block checkoutbtn" type="button" name="invoice_details"  value="Go to Order Page">
      </a>
    </div>
     <?php
                      }
        
        ?>

It probably doesn't work because your "button" is actually a link. But I don't actually know what "output" you're trying to get...

This is the output i'm trying to get

That comes from

$sql2 = " SELECT order_id FROM ordered_items GROUP BY order_id WHERE order_id = '".$row[order_id]."'  ";

this query. So if this query isn't working then your next step is to learn more about $row.
