Change the order of totals - magento

Question

I'm having some troubles figuring out how to change the order of the totals in the transactional email templates (In Magento).
Basicly I want the 'Tax' row to be at the very bottom - below 'Grand total incl. tax'.
I know that this is the code, that prints the rows. But I can't seem to figure out how to change the order of the rows.
<?php foreach ($this->getTotals() as $_code => $_total): ?>
<?php if ($_total->getBlockName()): ?>
<?php echo $this->getChildHtml($_total->getBlockName(), false); ?>
<?php else:?>
<tr class="<?php echo $_code?>">
<td <?php echo $this->getLabelProperties()?>>
<?php if ($_total->getStrong()):?>
<?php echo $this->escapeHtml($_total->getLabel());?>
<?php else:?>
<?php echo $this->escapeHtml($_total->getLabel());?>
<?php endif?>
</td>
<td <?php echo $this->getValueProperties()?>>
<?php if ($_total->getStrong()):?>
<?php echo $this->formatValue($_total) ?>
<?php else:?>
<?php echo $this->formatValue($_total) ?>
<?php endif?>
</td>
</tr>
<?php endif?>
Could anyone be of help with this problem?
Thanks and have a wonderful day!

Answer 1

Method 1: Modifying the theme template file.
Copy app/design/frontend/base/sales/order/totals.phtml to your theme file and open it.
Add the following to the top of it.
if($tax = $this->getTotal('tax'))
{
$this->removeTotal('tax');
$this->addTotal($tax, 'grand_total');
}
This code will remove the tax from the totals list, then re-add it below the Grand Total. You should move the totals.phtml file into your custom theme folder so upgrades won't override it.
Method 2: Overriding the core block file.
You can do the same patch by overriding the core Totals block by doing the following:
Copy app/code/core/Mage/Sales/Block/Order/Totals.php to app/code/local/Mage/Sales/Block/Order/Totals.php
Open app/code/local/Mage/Sales/Block/Order/Totals.php and change the getTotals() function to the following:
public function getTotals($area=null)
{
//Move tax below grand_total
if($tax = $this->getTotal('tax'))
{
$this->removeTotal('tax');
$this->addTotal($tax, 'grand_total');
}
$totals = array();
if ($area === null) {
$totals = $this->_totals;
} else {
$area = (string)$area;
foreach ($this->_totals as $total) {
$totalArea = (string) $total->getArea();
if ($totalArea == $area) {
$totals[] = $total;
}
}
}
return $totals;
}
