Configurable product options – get price difference in brackets

Question

I know that a few themes have this by default but my one doesn't, and i just cant get this to work.

I have a configurable Product which has three options with different prices. I want to show the price difference to the linked simple product in brackets. So it should basically look like this:

Price: XX€

(x) option 1 – ( ) option 2 (+ 4,00$) – ( ) option 3 (+ 12,00$)

How do i do this?

Answer 1

I think you want to display it on view.phtml but you could make this where you want.

$product -> configurable

 <?php echo 'Price: ' . $product->getPrice() . '<br>'; ?>

    <?php 
$childs = $product->getTypeInstance()->getUsedProducts(); 
foreach($childs as $child){
    echo $child->getName() . ' - ' ; 
} 
 ?>

this should display what you want, but check that you make a good display with the first and last child to get the correct output.
