We want to add a fee of 3% for all payments made with credit card. We use Authorize.net, so the fee would apply only if the payment id is ‘aim’.

Here is our current code, but it is applying to all payment methods:

add_filter(‘FHEE__bc_ee_apply_transaction_surcharge__apply_surcharge’, ‘__return_true’);
add_filter(‘FHEE__bc_ee_apply_transaction_surcharge__surcharge_details’, ‘ee_cc_surcharge_details’);

function ee_cc_surcharge_details() {
return array(
‘name’ => ‘Credit Card Surcharge’,
‘code’ => ‘credit-card-surcharge’,
‘description’ => ‘3% surcharge for credit card payments’,
‘percent’ => 3,
‘taxable’ => false,
);
}

/**
* DO NOT EDIT ANYTHING EXCEPT DEFAULT SURCHARGE DETAILS
*
* bc_ee_apply_transaction_surcharge
*
* @param \EE_Checkout $checkout
* @return \EE_Checkout
*/
function bc_ee_apply_transaction_surcharge(EE_Checkout $checkout) {
// DEFAULT SURCHARGE DETAILS – EDIT THIS
$surcharge_details = apply_filters(
‘FHEE__bc_ee_apply_transaction_surcharge__surcharge_details’,
array(
// name for surcharge that will be displayed
‘name’ => ‘Credit Card Surcharge’,
// unique code used to identify surcharge in the db
‘code’ => ‘credit-card-surcharge’,
// description for line item
‘description’ => ‘3% surcharge for credit card payments’,
// percentage amount
‘percent’ => 3,
// whether or not tax is applied on top of the surcharge
‘taxable’ => false,
)
);

// STOP EDITING
// verify checkout
if (!$checkout instanceof EE_Checkout) {
return $checkout;
}

// verify cart
$cart = $checkout->cart;
if (!$cart instanceof EE_Cart) {
return $checkout;
}

// verify grand total line item
$grand_total = $cart->get_grand_total();
if (!$grand_total instanceof EE_Line_Item) {
return $checkout;
}

// check for existing surcharge
$existing_surcharge = $grand_total->get_child_line_item($surcharge_details[‘code’]);

// remove the surcharge if payment method is not ‘aim’
if ($existing_surcharge instanceof EE_Line_Item && $checkout->selected_method_of_payment !== ‘aim’) {
$grand_total->remove_item($existing_surcharge->ID());
$grand_total->recalculate_total_including_taxes();
$cart->set_grand_total($grand_total); // Ensure the cart is updated
return $checkout;
}

// apply new surcharge if payment method is ‘aim’ and surcharge does not already exist
if ($checkout->selected_method_of_payment === ‘aim’ && !$existing_surcharge) {
EE_Registry::instance()->load_helper(‘Line_Item’);
$pre_tax_subtotal = EEH_Line_Item::get_pre_tax_subtotal($grand_total);
$pre_tax_subtotal->add_child_line_item(

‘LIN_unit_price’ => 0,
‘LIN_percent’ => $surcharge_details[‘percent’],
‘LIN_quantity’ => NULL,

‘LIN_order’ => 0,

‘LIN_type’ => EEM_Line_Item::type_line_item,
‘LIN_code’ => $surcharge_details[‘code’],
))
);
$grand_total->recalculate_total_including_taxes();
$cart->set_grand_total($grand_total); // Ensure the cart is updated

return $checkout;
