Zero charge for certain items

Hi @lh23,

have a look on following filter and implement it as you want ??

Best regards,

Thank you for the reply, that may be beyond my abilities but I will play around with it sometime!

Thanks for the plugin as well.

Hi Karolina, I don’t expect you to offer free support but thought I would ask. I am trying this code and getting errors, but I am guessing at some of the terms:

/** Woocommerce – don’t add Stripe fee if only a free purchase
*/
function my_pay4pay_handle_free( $do_apply , $amount , $cart_subtotal , $current_payment_gateway ) {
if ( amount_is_0() )
return false;
else
return $do_apply;
}
add_filter( “woocommerce_pay4pay_apply”, ‘my_pay4pay_handle_free’ , 10 , 4 );

Hi @lh23, could you send me as well the amout_is_0() function? I will test it.

Hi @vyskoczilova,
I am just trying to tell it that if the cart subtotal is zero, not to apply the fee.

/** Woocommerce – don’t add Stripe fee if only a free purchase
*/
function my_pay4pay_handle_free( $do_apply , $amount , $cart_subtotal , $current_payment_gateway ) {
if ($cart_subtotal == 0)
return false;
else
return $do_apply;
}
add_filter( “woocommerce_pay4pay_apply”, ‘my_pay4pay_handle_free’ , 10 , 4 );

I think the two things I’m having trouble with are getting the cart subtotal:
if ($cart_subtotal == 0)
I have also tried: WC()->cart->subtotal == 0

Also, does this code go in functions.php or class-pay4play.php

Thanks again

Hi @lh23,

I understood what are you trying to achieve, but I wanted to know how it was checked to be able to catch the problem. This one should work fine for you:

/** Woocommerce – don’t add Stripe fee if only a free purchase
*/
function my_pay4pay_handle_free( $do_apply , $amount , $calculation_base , $current_payment_gateway ) {
	
	$cart = WC()->cart;
	
	if ( wc_prices_include_tax() ) {
		$subtotal = intval( $cart->subtotal );
	} else {
		$subtotal = intval( $cart->subtotal_ex_tax );
	}
	
	if ($subtotal == 0) {
		return false;	
	} else {
		return $do_apply;
	}
}
add_filter( "woocommerce_pay4pay_apply", "my_pay4pay_handle_free" , 10 , 4 );

Add it to your functions.php.

Have a nice weekend!
