Update price on product page when qty value changed

[DiffuSer]

Does anyone faced with the realization of this task? I tried to update to finalize product.js prices, as well as the choice of combinations, but i am too bad versed in the code Prestashop. Someone help me plz.

[DiffuSer]

How it is implemented for the combinations?

[DiffuSer]

Can somebody help me? I make this by using updateDisplay(); from product.js for my multiply var, but... It works onto product page with combinations, like this: http://demo.blackzone.cc/prestashop/product.php?id_product=2

And do not work without combinations: http://demo.blackzone.cc/prestashop/product.php?id_product=1

 

Anybody, help me pls!

I just modify the updateDisplay function this way :

 

$('#our_price_display').text(formatCurrency(productPrice * $('#quantity_wanted').val(), currencyFormat, currencySign, currencyBlank));

 

and

 

$('#old_price_display').text(formatCurrency(productPriceWithoutReduction * $('#quantity_wanted').val(), currencyFormat, currencySign, currencyBlank));

 

and added this test on the function's top

 

if(!isInt($('#quantity_wanted').val()) || $('#quantity_wanted').val()<=0){ $('#quantity_wanted').val(1)}

 

isInt look like this :

function isInt(x) {  var y=parseInt(x);  if (isNaN(y)) return false;  return x==y && x.toString()==y.toString();}

 

 

it work great for me.

http://demo.blackzon...hp?id_product=8, not working for me. =(

 

Products without combinations set price to zero.
