Question
I am working with an Invoice in php. I want to show the DUE part only if there is any due in the invoice otherwise it should remain hide. In my printOrder.php the codes are given below:
Here is the total code of printOrder.php file:
<?php
require_once 'core.php';
$orderId = $_POST['orderId'];
$sql = "SELECT order_date, client_name, client_address, client_contact, sub_total, vat, total_amount, discount, grand_total, paid, due, invoice_no FROM orders WHERE order_id = $orderId";
$orderResult = $connect->query($sql);
$orderData = $orderResult->fetch_array();
$orderDate = $orderData[0];
$clientName = $orderData[1];
$clientAddress = $orderData[2];
$clientContact = $orderData[3];
$subTotal = $orderData[4];
$vat = $orderData[5];
$totalAmount = $orderData[6];
$discount = $orderData[7];
$grandTotal = $orderData[8];
$paid = $orderData[9];
$due = $orderData[10];
$invoiceNo = $orderData[11];
$orderItemSql = "SELECT order_item.product_id, order_item.rate, order_item.quantity, order_item.total,
product.product_name, order_item.categories_name, order_item.subcategory_name, order_item.brand_name FROM order_item
INNER JOIN product ON order_item.product_id = product.product_id
WHERE order_item.order_id = $orderId";
$orderItemResult = $connect->query($orderItemSql);
$f = new NumberFormatter("en", NumberFormatter::SPELLOUT);
?>

Simply check the due value right, I assume you get due amount 0 or null or some value
<?php
if($due>0&&$due!=""){
?>
<tr>
<th colspan="2"><?php echo $due; ?></th>
</tr>
<?php
}
?>
If your $due variable does not help you to decide, then check the variable which decides that due part, include the due part inside an if condition, something like following (General PHP)
if(condition){ //this tr will be printed only if your condition will be true.
echo '<tr>.....</tr>';
}
UPDATE: Example displaying conditional row in a table
Single PHP File
<?php
$total_amount = 100;
$due = 20;
$data = array();
?>
<table>
<thead>
<tr>
<th></th>
<th></th>
</tr>
</thead>
<tbody>
<?php
foreach($data as $d){
?>
<tr>
<td></td>
<td></td>
</tr>
<?php
}
?>
<tr>
<th colspan="2"><?php echo $total_amount ?></th>
</tr>
<?php
if($due>0&&$due!=""){
?>
<tr>
<th colspan="2"><?php echo $due; ?></th>
</tr>
<?php
}
?>
</tbody>
</table>
Use colspan property of the td and th to match with the number of columns in a table.
