Add individual charges for each payment method as a flat rate and/or as a percentage of the cart total. The plugin first calculates the percentage rate and then adds the fixed rate on top. Coupons are not supported. (Sorry guys. I tried, but no way.)

You will find a stable version in WordPress plugin directory.

Previous versions have been created by Jörn Lund, who abandoned this project due to a pile of other projects in 2016. See the previous GitHub for details. The new version is maintained by Karolína Vyskočilová since 2017.

• 100% compatible with WPML (use WPML String translate module)
• Fixed charge and/or a percentage of cart total
• Possibility to disable for free/zero shipping
• Translation ready
• German, Spanish (muchas graçias!), Turkish (çok teşekkürler!), Czech (díky), Italian (grazie) and Dutch localization (bedankt)

• none

Applied to the payment gateway fee before it is added to woocomerce' cart.

Example:

function my_pay4pay_amount( $amount , $calculation_base , $current_payment_gateway , $taxable , $include_taxes , $tax_class ) {
	if ( my_customer_complained_too_much() )
		return $amount * 10;
	else
		return $amount;
}
$current_gateway_id = 'cod';
add_filter( "woocommerce_pay4pay_{$current_gateway_id}_amount", 'my_pay4pay_amount' , 10 , 6 );

Handle if a payment fee is applied.

Example:

function my_pay4pay_handle_christmas( $do_apply , $amount , $cart_subtotal , $current_payment_gateway ) {
	if ( today_is_christmas() )
		return false;
	else
		return $do_apply;
}
add_filter( "woocommerce_pay4pay_apply", 'my_pay4pay_handle_christmas' , 10 , 4 );

Handle if a payment fee on a specific payment method should be applied.

Example:

function my_pay4pay_apply( $do_apply , $amount , $cart_subtotal , $current_payment_gateway ) {
	if ( my_customer_is_a_nice_guy() )
		return false;
	else
		return $do_apply;
}
$current_gateway_id = 'cod';
add_filter( "woocommerce_pay4pay_applyfor_{$current_gateway_id}", 'my_pay4pay_apply' , 10 , 4 );
