Product Attributes , prefix


Recommended Posts

Hi people,

Can anybody know how can I deseble prefix.. and use attributes , Option value

without + prefix.. ? Just the price I put in attributes (option value)


I want to sell images on my stock.. and I need a 3 options

When somebody click to product.. that he have option example:

Low resolution 5$

Medium res. 10 $

High res. 15 $


At this moment if I put price on that product 5 $

and put option Medium res. with 10$

the total oreder will be 5 $ + 10$ = 15$


How can I correct this?


Thank you

I am having the same issue... did u get the solution for prefix???

please share that with me also... that will be geat.


I made the following code change to both shopping_cart.php files. I added $product_prices as a parameter to attribute_price(). I changed all references to attribute_price() to not do an addition of $product_prices and instead do the math here. I made up a price_prefix of '@' to fix the price to the given value instead of doing addition or subtraction.


function attributes_price($products_id, $products_prices) {

$attributes_price = 0;


if (isset($this->contents[$products_id]['attributes'])) {


while (list($option, $value) = each($this->contents[$products_id]['attributes'])) {

$attribute_price_query = tep_db_query("select options_values_price, price_prefix from " . TABLE_PRODUCTS_ATTRIBUTES . " where products_id = '" . (int)$products_id . "' and options_id = '" . (int)$option . "' and options_values_id = '" . (int)$value . "'");

$attribute_price = tep_db_fetch_array($attribute_price_query);

if ($attribute_price['price_prefix'] == '+') {

$attributes_price += $attribute_price['options_values_price'];


else if ($attribute_price['price_prefix'] == '@') {

return $attribute_price['options_values_price'];


else {

$attributes_price -= $attribute_price['options_values_price'];





return $products_price + $attributes_price;
