Hide payment via bank transfer if user has credit in wallet?

@ohdearbambi Yes, you can hide payment methods using the WooCommerce filter woocommerce_available_payment_gateways.

I tried to make the code to do this, but it ended up breaking my site. Can you help correct the code I’ve made?

//remove payment via transfer if customer has credit available//
add_filter( 'woocommerce_available_payment_gateways', 'unset_gateway_if_credit_available' );

function unset_gateway_if_credit_available( $available_gateways ) {
    if ( is_admin() ) return $available_gateways;
    if ( ! is_checkout() ) return $available_gateways;
        $unset = false;
        $current_wallet_amount = apply_filters( 'woo_wallet_partial_payment_amount', woo_wallet()->wallet->get_wallet_balance( get_current_user_id(), 'edit' ) );
        $rest_amount = get_woowallet_cart_total () - $current_wallet_amount;
        $current_cart_total = WC()->cart->cart_contents_total;
        if ( $rest_amount >= $current_cart_total ) {
            $unset = true;;
            break;
        }
    if ( $unset == true ) unset( $available_gateways['bcas'] );
    return $available_gateways;
}

@ohdearbambi Please try this code.

if(!function_exists('woocommerce_available_payment_gateways_callback')){
    function woocommerce_available_payment_gateways_callback($_available_gateways){
        if(!is_admin() && !is_wallet_rechargeable_cart() && is_full_payment_through_wallet()){
            foreach ($_available_gateways as $id => $gateway){
                if('wallet' != $id){
                    unset($_available_gateways[$id]);
                }
            }
        }
        return $_available_gateways;
    }
}
add_filter('woocommerce_available_payment_gateways', 'woocommerce_available_payment_gateways_callback');

It works perfectly! Thanks so much for the help.
