Using checkbox at Tax tab: "Save shipping with tax in the database so it is shown with tax in the account information"
This checkbox is very important and can make some of your payment methods not showing the proper totals, because the calculation will look like this
products including tax: 100
shipping including tax: 10
payment fee incl. tax: 15
tax (25%): 25
total: 125

some payment methods such as paypal (legacy) don't use order total column of the database, but rather try to count the total from the subtotals which lead to incorrect calcution when the above checkbox is checked.

The original paypal legacy extra info code:

Code: Select all

<?php
$db1 = new ps_DB();
$q = "SELECT country_2_code FROM #__vm_country WHERE country_3_code='".$user->country."' ORDER BY country_2_code ASC";
$db1->query($q);

$url = "https://www.paypal.com/cgi-bin/webscr";
$tax_total = $db->f("order_tax") + $db->f("order_shipping_tax");
$discount_total = $db->f("coupon_discount") + $db->f("order_discount");
$post_variables = Array(
"cmd" => "_ext-enter",
"redirect_cmd" => "_xclick",
"upload" => "1",
"business" => PAYPAL_EMAIL,
"receiver_email" => PAYPAL_EMAIL,
"item_name" => $VM_LANG->_('PHPSHOP_ORDER_PRINT_PO_NUMBER').": ". $db->f("order_id"),
"order_id" => $db->f("order_id"),
"invoice" => $db->f("order_number"),
"amount" => round( $db->f("order_subtotal")+$tax_total-$discount_total, 2),
"shipping" => sprintf("%.2f", $db->f("order_shipping")),
"currency_code" => $_SESSION['vendor_currency'],

"address_override" => "1",
"first_name" => $dbbt->f('first_name'),
"last_name" => $dbbt->f('last_name'),
"address1" => $dbbt->f('address_1'),
"address2" => $dbbt->f('address_2'),
"zip" => $dbbt->f('zip'),
"city" => $dbbt->f('city'),
"state" => $dbbt->f('state'),
"country" => $db1->f('country_2_code'),
"email" => $dbbt->f('user_email'),
"night_phone_b" => $dbbt->f('phone_1'),
"cpp_header_image" => $vendor_image_url,

"return" => SECUREURL ."index.php?option=com_virtuemart&page=checkout.result&order_id=".$db->f("order_id"),
"notify_url" => SECUREURL ."administrator/components/com_virtuemart/notify.php",
"cancel_return" => SECUREURL ."index.php",
"undefined_quantity" => "0",

"test_ipn" => PAYPAL_DEBUG,
"pal" => "NRUBJXESJTY24",
"no_shipping" => "1",
"no_note" => "1"
);
if( $page == "checkout.thankyou" ) {
$query_string = "?";
foreach( $post_variables as $name => $value ) {
$query_string .= $name. "=" . urlencode($value) ."&";
}
vmRedirect( $url . $query_string );
} else {
echo '<form action="'.$url.'" method="post" target="_blank">';
echo '<input type="image" name="submit" src="https://www.paypal.com/en_US/i/btn/x-click-but6.gif" border="0" alt="Click to pay with PayPal - it is fast, free and secure!" />';

foreach( $post_variables as $name => $value ) {
echo '<input type="hidden" name="'.$name.'" value="'.htmlspecialchars($value).'" />';
}
echo '</form>';

}
?>

Recommended modification to show the correct total:

Code: Select all

$tax_total = $db->f("order_tax") + $db->f("order_shipping_tax");

$shipping = $db->f("order_shipping");
