php loop problems

noob problem: i have some issues with a loop in php…here is the code (i used the same methodology for other pages and it works); the code it is supposed to display the names of the products from a order, it works, but it is not showing the very first product , i don’t know why :

<?php $i=1; while($row_selectOrderItems = mysqli_fetch_array($result_selectOrderItems)){ ?>
        <tr>
            <td> <?php echo $i; ?> </td>
            <td> <?php echo $row_selectOrderItems['pro_name']; ?> </td>
            <td> <?php echo $row_selectOrderItems['pro_price']; ?> </td>
            <td> <?php echo $row_selectOrderItems['q']; ?> </td>
            <td> <?php echo $row_selectOrderItems['q']*$row_selectOrderItems['pro_price']; ?> </td>
        </tr>
        <?php $i++; } ?> 

and here is the code where i used mysqli_fetch_array before the loop

        $query_selectOrderItems = "SELECT *,order_items.quantity AS q  FROM orders,order_items,products WHERE order_items.order_id='$order_id' AND order_items.pro_id=products.pro_id AND order_items.order_id=orders.order_id";
        $result_selectOrderItems = mysqli_query($con,$query_selectOrderItems);                  
        $row_selectOrderItems=mysqli_fetch_array($result_selectOrderItems);

Does anyone have any idea how should i modify this code? Thank you!

Answer

$row_selectOrderItems=mysqli_fetch_array($result_selectOrderItems);

remove this line, so that, it will not read the 1st result at starting. Now, when you use it in the while loop, it reads the first line
