Two or more currencies

Hi,

i'm trying to add some kind of dropdown where my customers can choose what currency is used in my shopping cart (or maybe whole site). Currently i would like to let them choose between dollar or euro but i want to add some currencies later. So just to be clear i would also like if they could change currency if there is already something in the cart. I really dont know how to do this and if it is possible...
Thanks

this is possible, but will take some custom coding to accomplish.

add the following code to the page where the currency selection will be made at line 1:

<?php

@session_start();

switch((isset($_POST['currency']))?$_POST['currency']:"") {

    case "USD":

        $_SESSION['currencySymbol'] = "$";

        $_SESSION['currencyCode'] = "USD";

        break;

    case "EUR":

        $_SESSION['currencySymbol'] = "&euro;";

        $_SESSION['currencyCode'] = "EUR";    

        break;

    default:

        $_SESSION['currencySymbol'] = "$";

        $_SESSION['currencyCode'] = "USD";    

}

?>

use this code in the body to add the currency select list:

<form id="form1" name="form1" method="post"  action="">

  <label>

    <select name="currency" id="currency">

      <option value="USD" selected="selected">USD</option>

      <option value="EUR">Euro</option>

    </select>

  </label>

  <label>

    <input type="submit" name="button" id="button" value="Submit" />

  </label>

</form>

you will then need to edit the eCart object file to use the dynamically set curency symbol.

in my example, the eCart objec is named eCart4, look for the following code:

$eCart4 = new eCart4_Definition("eCart4", 0, "$", "", true, 2, 0, "oz", true, 2, 1, 0);

in your eCart file, it will be slightly different, anywhere that says "eCart4" substitute with the name if your eCart object

change that to:

$eCart4 = new eCart4_Definition("eCart4", 0, "".(isset($_SESSION['currencySymbol']))?$_SESSION['currencySymbol']:"$"."", "", true, 2, 0, "oz", true, 2, 1, 0);

after running the checkout wizard, you will also need to modify the confirm page, to change the parameter that passes the currency code to the gateway use the dynamic one. this change will be different based on the payment gateway you are using, let me know what payment gateway you plan to use and i can tell you the code that will need to be changed.

This changes only the symbol but i also want the value to change. To be precise if a customer selects euro and usd is selected by default i want all numbers in my cart to be recalculated to euro (1USD = 0,75E). I think this could be similar to this you already wrote but i dont know where to put the calculation formulas... I dont use any payment gateway so there shouldn't be any problems.

That is not supported by eCart and would take quite a bit more custom coding. This is not something that we would be able to assist with here in the forums, if you would like help creating this, Please sign up for a Premiere Support ticket appointment where we could work with you in a one on one session.
