Add product with my custom price to cart

[abdess]

Hello everyone,

 

in prestashop (1.6.1.5) on product detail page I have my custom price for the current product.

Now when I click on "add to cart" the standard product is added to the cart with standard price. I will add the product with my custom price to cart .

 

Could anyone give me some needable ideas in the right direction please...

 

Thank you very much

what module are you using if any for custom price?  if you have module for this have you contacted the developer?

 

also please post link too product and how to produce as there is not not enough information for community to help.

Example

public function getOrderTotal($with_taxes = true, $type = Cart::BOTH, $products = null, $id_carrier = null, $use_cache = true)
    {
    	$order_total = parent::getOrderTotal($with_taxes, $type, $products, $id_carrier, $use_cache);
    	// custom here
	$order_total += 5; // example
    	return Tools::ps_round((float)$order_total, $compute_precision);
    }
