WooCommerce Hide Payment Gateway for Custom Attribute - wordpress

Question

Just starting in my WordPress/WooCommerce journey.
I found a question on here from a while back asking about restricting payment gateways for a specific attribute selection. I've tried to integrate this into my site and I cannot get it working! I've added the Attribute and Terms, and the slugs are as follows - pay_now_deposit (attr) and pay_now / deposit (terms).
I'm looking to restrict Klarna payments for those paying by deposit, and the code I have is below -
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_pay_now_deposit', (array) $values['data']->get_attributes() ) ) {
foreach ($values['data']->get_attributes() as $attribute => $variation);
// Replace 'small' with your value.
if ($variation == 'deposit') $in_cart = true; //edited
}
}
if ( $in_cart ) {
unset($available_gateways['klarna_payments']);
}
else {
unset($available_gateways['cod']);
}
return $available_gateways;
}
Any advice on where I'm going wrong would be greatly appreciated!

Try to add a break statement.
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 ) {
if ( array_key_exists( 'pa_pay_now_deposit', (array) $values['data']->get_attributes() ) ) {
foreach ( $values['data']->get_attributes() as $attribute => $variation ){
if ( $variation == 'deposit' ){
$in_cart = true; //edited
break;
}
}
}
if( $in_cart ){
break;
}
}
if ( $in_cart ) {
unset( $available_gateways['klarna_payments'] );
}else {
unset( $available_gateways['cod'] );
}
return $available_gateways;
}
