Working with multiple currency

This plugin adds fees with method add_fee.
WC()->cart->add_fee( $fee_name, $fee_cost, $is_taxable, $tax_class );

So this function adds fee in the current currency.

I have tested in a test website:

Product: https://test.pexlechris.dev/product/test-15-kg/
Checkout: https://test.pexlechris.dev/checkout/
Currency Switcher: in Footer

and works fine (at the current currency)

Hi @pexlechris

Thanks for your great question. There’s always a way, and I like this idea; however, I’ve been sick and not focusing on development of this free plugin. If you hire someone to fix this up for you I’d be happy to take a look and maybe incorporate it.

Hi.
Ok thank you. I wish you a fast recovery.

Hi Pexle. Maybe it doesn’t work with my currency plugin ‘WOOCS – WooCommerce Currency Switcher’.
Can you have a look here:

My default currency is ALL and the gift wrapper fee is set to 150 ALL. When switching to Euro it stays 150 Eur.

thank you

@spartakg This plugin is so similarly named to the one I maintain, so I got confused here. Never mind what I said earlier. WOOCS might or might not work with the Gift Wrapper – not tested.

@spartakg In my test site I use also plugin ‘WOOCS – WooCommerce Currency Switcher’.

And I can see in your website that when currency is euro, and gift wrapper is checked, I can see in the fees:
Gift wrapper 150.00€
Also when the other currency is checked and Gift wrapper is also checked I can see in fees:
Gift wrapper L 150

This is how should work and works! So what is the problem?
Can you provide a screenshot here (with the help of some external service, maybe cloud storage such as Google Drive)?

Thanks

@pexlechris Hi.

No L 150 is around 1.29 eur. So at euro currency it should convert to around 1.29 eur but it stays 150 eur.
If you notice the product amount converts ok when switching currency but gift wrapper amount does not convert.

Do you want access to my test website ?

Now I understood the case,
You can ask the currency Plugin how manage the cart fees
Or change it with a php hook.

Do you want help with the hook?

You said that you also use ‘WOOCS – WooCommerce Currency Switcher’. Have you done any customization or hook in your case or just works for you?

I will write to the currency plugin developers. I would also appreciate your help until I get a response from them. Is the hook a solid solution?

You can see in my test site how it works. I think that dont convert the euro to dollars and vice versa, as you wan. Just changes the symbols €, $

Yes, you can use the filter pre_option_tgpc_gift_wrapper_cost to change fee cost.

add_filter('pre_option_tgpc_gift_wrapper_cost', function($fee){
   if( $currency == 'dollars' ){ // you need to find out from currency plugin how to get current currency
      $fee = $fee*1.2; // Your calculation
   }
   return $fee;
});

The above hook is just an example

Hi Pexle.
Where do I add this hook ?

thank you

To add this hook, you can read this blog post:
How to add PHP Hooks in your WordPress Site

But have in mind that this hook will not work as it is.

To get the current currency, maybe this function will work

function pex_get_current_currency(){
   $currency = do_shortcode('[woocs_show_current_currency text=""]');
   $currency = strip_tags($currency);
   $currency = trim($currency);
   $currency = trim($currency, ' ');
   return $currency;
}

Hi. I was able to find the WOOCS code to get the currency rate:

if (class_exists('WOOCS')) {
    global $WOOCS;
    $currencies = $WOOCS->get_currencies();
    $currrent = $WOOCS->current_currency;
   $rate = $currencies[$currrent]['rate'];
}

in the case of ALL rate is 1, in the case of EUR my rate is 0.008.
So the gift fee should be $fee * rate.

I tried to implement the following code but it returns 0 for both currencies.

add_filter(‘pre_option_tgpc_gift_wrapper_cost’, function($fee){
$fee = $fee*$rate ;
return $fee;
});

if (class_exists('WOOCS')) {
    global $WOOCS;
    $currencies = $WOOCS->get_currencies();
    $currrent = $WOOCS->current_currency;
   $rate = $currencies[$currrent]['rate'];
}

In my site $rate returns 1. Maybe this is the default value and the problem.

The filter that you can use is

add_filter('pre_option_tgpc_gift_wrapper_cost', function($fee){
	if( class_exists('WOOCS') ) {
		global $WOOCS;
		$currencies = $WOOCS->get_currencies();
		$currrent = $WOOCS->current_currency;
	    $rate = $currencies[$currrent]['rate'];
		if( $currrent == 'USD' ){ // you need to find out from currency plugin how to get current currency
			$fee = $fee*$rate; // Your calculation
		}
	}

   return $fee;
});

I think the $fee variable has no value. I applied and returned zero. So I tried to manually put the $fee = 150 and it worked.

add_filter('pre_option_tgpc_gift_wrapper_cost', function($fee){
	if( class_exists('WOOCS') ) {
		global $WOOCS;
		$currencies = $WOOCS->get_currencies();
		$currrent = $WOOCS->current_currency;
	    $rate = $currencies[$currrent]['rate'];
		if( $currrent == 'EUR' ){ // you need to find out from currency plugin how to get current currency
			$fee = 150*$rate; // Your calculation
		}
	}

   return $fee;
});

Thank you very much for giving me the direction to the solution. Here is the list of woocs functions if you ever need it.
