add unsupported paypal currency to woocommerce

/**
 * this code will add an unsupported currency to Woocommerce (tested up to v3.1.2 on WP 4.8.2) 
 * it will convert any amounts including a cart discount, tax or shipping into a supported currency (in this case USD)
 * paypal HTML variables can be found at https://developer.paypal.com/webapps/developer/docs/classic/paypal-payments-standard/integration-guide/Appx_websitestandard_htmlvariables/#id08A6HI00JQU
 * payment processing can then be done via Paypal
 * this example uses the UAE Dirham (or AED). Change the currency symbol and abbreviation to suit your environment.
 * note - any orders placed this way are automatically placed on-hold by Woocommerce due to an amount & currency mismatch and MUST be manually updated to processing or complete, esp with virtual or downloadable orders.
 * stock or inventory management does NOT work with this workaround - there is an additional step needed please see https://vinefruit.net/woocommerce-currency-tweak/

Hello,

Thank you for all the work you have done, is this the latest code for wordpress and woocommerce, will like to give it a try and see?

Howard

Thank you for all your work, the only thing that ever worked for me 💯 👍

Thanks a lot, that was very useful, works like a charm.

Thanks! Your code works perfectly. Could you please tell me how to use the step 3 with more than one currency? I'm using a currency switcher and I tried it with other currencies and it gave me an error. Can't use "get_currency" again.

How I must edit the code so I have fixed exchange ratio not Google's?

Hi all, sorry I am not notified of comments, please contact me via my website https://vinefruit.net should you get stuck.

@501digitalmedia - I'm not sure how you would use this for more than one currency sorry. Maybe try to use the paypal express plugin instead of paypal std - https://woocommerce.com/products/woocommerce-gateway-paypal-express-checkout/
The PayPal Express extension will allow you to charge in more currencies, but you'll need to set your shop base currency to match. You can learn how to do that here: http://docs.woocommerce.com/document/shop-currency/

@therampagerado - yes there is a way, use this instead of Step 3. In this case 1 USD = 3.68 AED so adjust your currency rate accordingly below

/Step 3 – Code to change ‘AED’ currency to ‘USD’ before checking out with Paypal through WooCommerce:/

add_filter('woocommerce_paypal_args', 'convert_aed_to_usd');
function convert_aed_to_usd($paypal_args){
if ( $paypal_args['currency_code'] == 'AED'){
$convert_rate = 3.68; //set the converting rate
$paypal_args['currency_code'] = 'USD'; //change AED to USD
$i = 1;

	while (isset($paypal_args['amount_' . $i])) {  
		$paypal_args['amount_' . $i] = round( $paypal_args['amount_' . $i] / $convert_rate, 2);
		++$i;  
    }  
	if ( $paypal_args['shipping_1'] > 0 ) {
		$paypal_args['shipping_1'] = round( $paypal_args['shipping_1'] / $convert_rate, 2);
	}
	
	if ( $paypal_args['discount_amount_cart'] > 0 ) {
		$paypal_args['discount_amount_cart'] = round( $paypal_args['discount_amount_cart'] / $convert_rate, 2);
	}
	if ( $paypal_args['tax_cart'] > 0 ) {
		$paypal_args['tax_cart'] = round( $paypal_args['tax_cart'] / $convert_rate, 2);
	}
}

return $paypal_args;
}

Thanks for this @vinefruit
I am looking for this but for multiple currencies, exactly like @501digitalmedia reported.

Unfortunately I am not a developer, otherwise, it wouldn't be too hard to add more currencies to the script, right?

If anyone has the solution, please share. I will do the same if I find the solution.

Cheers!

Greatly appreciated @vinefruit. You saved me a ton of time. Thanks very much!

Hey, do you by any chance have an updated version of this? Its seems the amount is not getting passed. Thanks

is there a specific paypal payment plugin that needs to be used in order for this to work? those of you who were to get it to work, can you share what paypal plugin are you using? I'm having a hard time getting this to work, I'm using WooCommerce PayPal Checkout Gateway by WooCommerce.. Any help is greatly appreciated..
