Prestashop currencies

Hi to all

I am really not understanding how the currencies and the conversion of prices are working.

From which file/other function is the function "convertPrice", from tools.php called? I don't find it anywhere...

Kind regards

Andries

In classes/Tools.php there is function

    /**
   * Return price converted
   *
   * @param float $price Product price
   * @param object $currency Current currency object
   */
   static public function convertPrice($price, $currency = NULL)
   {
       if ($currency === NULL)
           $currency = Currency::getCurrent();
       $c_id = (is_array($currency) ? $currency['id_currency'] : $currency->id);
       $c_rate = (is_array($currency) ? $currency['conversion_rate'] : $currency->conversion_rate);
       if ($c_id != intval(Configuration::get('PS_CURRENCY_DEFAULT')))
           $price *= $c_rate;
       return $price;
   }



Also in classes/Product.php there is similar functions but that are calling displayPrices() from tools.php

hi thanks for the reply

It is indeed this function where I am talking about. I just need to know where it is called from.

This is the issue I have: when I click on another currency, only the display of the sign changes, and the price is still displayed in the old currency. However when I proceed to the order, the prices are displayed (and converted) correctly at that moment.

I have been looking around, but as you mention in product.php, the function displayPrice is called, but the function displayPrice don't call for the function convertPrice. I tried to add this call, and prices were displayed correctly, but when proceeding to the order, it guess it is called again, and the conversion takes place twice.

If i echo next to the price the conversion rate, or a var_dump of the $currency object, everything is really as it has to be... I have the feeling that somehow this function convertPrice is no longer called... So I would like to check my code, and see if I didn't remove it anywhere. But I was hoping that someone from PrestaShop or another developer could point me out where the function converPrice should be called...

I am not sure but i think it is going like this.
When you click on some currency JavaScript function is called and it make submit.
Page reloads with new currency id which is forwarded to converPrice function.
For example call is made in product-list.tpl

    <span class="price" style="display: inline;">{if !$priceDisplay}{convertPrice price=$product.price}{else}{convertPrice price=$product.price_tax_exc}{/if}



My guess that maybe there is some JavaScript error that stops this process.
