Hide payment method if specific variation selected is blocking plugins [duplicate] - woocommerce

Question

In Woocommerce, i want to hide the credit card payment option if a specific product variation is in the cart. Please help.
Thanks.
This is what i have working now. I assigned a separate shipping class to each variation i want to disable a specific payment method at checkout. But it would be much easier if i coud target specific attribute values, so i don't have to assign a shipping class.
<?php
add_filter('woocommerce_available_payment_gateways', 'conditional_payment_gateways', 10, 1);
function conditional_payment_gateways( $available_gateways ) {
$shipping_class_target = 106; // the shipping class ID assigned to specific variations
$in_cart = false;
foreach ( WC()->cart->get_cart_contents() as $key => $values ) {
if ( $values[ 'data' ]->get_shipping_class_id() == $shipping_class_target ) {
$in_cart = true;
break;
}
}
if ( $in_cart ) {
unset($available_gateways['cod']); // unset 'cod'
}
else {
unset($available_gateways['bacs']); // unset 'bacs'
}
return $available_gateways;
}

If you are looking to check the variations for each item in the cart, you have to lookup the attributes $product->get_attributes() and then loop through those and get the array key and value for each.
In this example, I used
Size (pa_size) and Small
add_filter('woocommerce_available_payment_gateways', 'conditional_payment_gateways', 10, 1);
function conditional_payment_gateways( $available_gateways ) {
$in_cart = false;
foreach ( WC()->cart->get_cart_contents() as $key => $values ) {
// See if there is an attribute called 'pa_size' in the cart
// Replace with whatever attribute you want
if (array_key_exists('pa_size', (array) $values['data']->get_attributes() ) ) {
foreach ($values['data']->get_attributes() as $attribute => $variation);
// Replace 'small' with your value.
if ($variation == 'small') $in_cart = true; //edited
}
}
if ( $in_cart ) {
unset($available_gateways['cod']); // unset 'cod'
}
else {
unset($available_gateways['bacs']); // unset 'bacs'
}
return $available_gateways;
}
