Running Math on Price Variables


harkey

Recommended Posts

Hello, I am trying to run some mathematical functions on products with special prices.

On both the orignal and special price values.

 

I tried this...

$currencies->display_price($product_info['products_price'], tep_get_tax_rate($product_info['products_tax_class_id']))   // for the original price

$currencies->display_price($new_price, tep_get_tax_rate($product_info['products_tax_class_id'])) // special price

The variables return a value of 0, and so I am aware that they are not being called correctly.

 

$product_info['products_price'] // returns correct value in american currency only 
$new_price //correct value in american currency.

 

How the original price and specials price be called to be cross currency compatible, and also be able to have mathmetical functions run?
