You can add as many currencies as you like. It uses Google Finance to get up to date foreign exchange information.

Now drag the widget to your desired sidebar and enjoy.

You can also use the Shortcode option, for example:

Vanliga frågor

I don’t have any currencies in the drop downs

Check your currency lists have data in them in the WP Currency Converter settings page found at Settings -> WP Currency Converter.

Make sure you use the three letter currency acronym as per the ISO 4217 standard

This plugin uses Google Finance for it’s calculations so ensure the currency is one they support.

Can I add more currencies?

You can add any currency by it’s currency acronym as long as it’s in the ISO 4217 standard list.

I always see the error: ”Error: Currency conversion temporarily not available. Please try again.”

It’s likely that you’re not using a currency code that Google Finance recognises. To check you can try Googling for the currency conversion, eg. 25 AUD to USD (replace with your currency codes).

If you want to use this plugin still then you need to change the function wpccAjaxConvert to the code below as the google financial api is deprecated. function wpccAjaxConvert(){ require_once('wpccSymbols.php'); // currency symbols for conversions $currency_from = $_POST['wpcc_currency_from']; $currency_to = $_POST['wpcc_currency_to']; $amount = $_POST['wpcc_currency_amount']; $url = file_get_contents('' . $currency_from . '_' . $currency_to . '&compact=ultra'); $json = json_decode($url, true); $rate = implode(" ",$json); $total = $rate * $amount; $rounded = round($total); //optional, rounds to a whole number // return $rounded //or return $rounded if you kept the rounding bit from above if (!empty($rounded)){ echo '<p>' . __('Amount', 'wpcc') . ' (' . $currency_to . '): ' . $currency[$currency_to] . $rounded . '</p>'; } else { echo '<p class="wpcc_error">' . __('Error: Currency conversion temporarily not available. Please try again.', 'wpcc') . '</p>'; } exit(); }
