Currency Lookup Alternative

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('https://free.currencyconverterapi.com/api/v5/convert?q=' . $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();

}
