This bit of PHP code will display all the Voucher Codes from the Buy.at network.
<?php
$xml = simplexml_load_file("https://users.buy.at/ma/index.php/affiliateVoucherCodes/list?handle=0&filter_status=y&include_pending=1&include_active=1&include_expired=0&prog_id=0&vertical_id=0&orderby=date_added&dir=desc&format=xml&email=USERNAME&password=PASSWORD");
echo '<table>';
echo '<tr>
<th scope="col">Retailer</th>
<th scope="col">Description</th>
<th scope="col">Voucher Code</th>
<th scope="col">Start Date</th>
<th scope="col">End Date</th>
<th scope="col">Link</th>
</tr>';
foreach($xml->body->children() as $child)
{
if($child->status=='Active')
{
echo '<tr>';
echo '<td>' . $child->programme . "</td>";
echo '<td>' . $child->description . "</td>";
echo '<td>' . $child->offer_code . "</td>";
echo '<td>' . $child->start . "</td>";
echo '<td>' . $child->end . "</td>";
echo '<td><a href="' . $child->url . '" target="_blank" rel="nofollow" title="Visit website to use voucher code">Use Code</a></td>';
echo '</tr>';
}
}
echo '</table>';
?>
Remember to change the USERNAME and PASSWORD in the URL line to your own. There are also some parameters you can configure, I have it set to only show non-expired vouchers and in date order.
I use this code on my WP site, example here.
