Show Cash on delivery (COD) based on specific cities in Woocommerce - php

Question

In Woocommerce I am showing Cash on delivery payment method only for a particular city using the following code:
function payment_gateway_disable_city( $available_gateways ) {
global $woocommerce;
if ( isset( $available_gateways['cod'] ) && $woocommerce->customer->get_shipping_city() == 'New York') {
unset( $available_gateways['cod'] );
}
return $available_gateways;
}
add_filter( 'woocommerce_available_payment_gateways', 'payment_gateway_disable_city' );
It works fine. Now I need to handle multiple cities like Washington, San Francisco etc...
So I tried the following:
function payment_gateway_disable_city( $available_gateways ) {
global $woocommerce;
if ( isset( $available_gateways['cod'] ) && $woocommerce->customer->get_shipping_city() == 'New York', 'San Fransisco' ) {
unset( $available_gateways['cod'] );
}
return $available_gateways;
}
add_filter( 'woocommerce_available_payment_gateways', 'payment_gateway_disable_city' );
But it doesn't work… I get "WordPress experiencing technical difficulties".
Any help is appreciated.

The following code will enable COD payments for specific defined cities.
You need to use an array of allowed cities with in_array() PHP conditional function like:
add_filter( 'woocommerce_available_payment_gateways', 'cities_based_payment_gateway_cod' );
function cities_based_payment_gateway_cod( $available_gateways ) {
if ( is_admin() ) return $available_gateways; // Only on frontend
// HERE define the allowed cities in this array
$cities = array( 'New York', 'San Francisco' );
if ( isset( $available_gateways['cod'] ) && ! in_array( WC()->customer->get_shipping_city(), $cities ) ) {
unset( $available_gateways['cod'] );
}
return $available_gateways;
}
Code goes in functions.php file of your active child theme (or active theme). Tested and works.
