我正在使用php中的发票。我只想在发票中有任何到期日时显示DUE部分，否则应保留为隐藏状态。在我的printOrder.php中，代码如下：

这是printOrder.php文件的总代码：

    <?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);

?>

<?php

$connect->close();

我已经完成了几件事来实现自己的愿望。之后，代码如上。

1 个答案:

答案 0 :(得分：0)

只需检查正确的到期值，我假设您得到到期金额0或为null或某个值

<?php 
    if($due>0&&$due!=""){
    ?>
        <tr>
            <th colspan="2"><?php echo $due; ?></th>
        </tr>
    <?php
    }
?>

如果您的$ due变量不能帮助您确定，则检查确定该到期部分的变量，将到期部分包括在if条件中，例如以下内容（通用PHP）

if(condition){ //this tr will be printed only if your condition will be true.
   echo '<tr>.....</tr>';
}

更新：在表中显示条件行的示例
单个PHP文件

<?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>

使用td和th的colspan属性来匹配表中的列数。
