Enable/Disable payment gateways for specific shipping methods

The code needs better error handling. I was getting a null array error showing on the checkout page. Did a simple check if array was null and then added a dummy value to avoid the error.
/**
* Filter payment gateways.
*/
function my_custom_available_payment_gateways( $gateways ) {
$chosen_shipping_rates = WC()->session->get( ‘chosen_shipping_methods’ );
if( empty( $chosen_shipping_rates ) ) {
$chosen_shipping_rates = array(“Placeholder to avoid null value”);
}

// When ‘local delivery’ has been chosen as shipping rate
if ( in_array( ‘local_delivery’, $chosen_shipping_rates )
) :
// Remove bank transfer payment gateway
unset( $gateways[‘cod’] );
endif;
return $gateways;
}
add_filter( ‘woocommerce_available_payment_gateways’, ‘my_custom_available_payment_gateways’ );

Hello
I Write this code:

/**
* Filter payment gatways
*/
function my_custom_available_payment_gateways( $gateways ) {
$chosen_shipping_rates = WC()->session->get( ‘chosen_shipping_methods’ );
// When ‘local delivery’ has been chosen as shipping rate
if ( in_array( ‘flat_rate:4’, $chosen_shipping_rates ) || in_array( ‘flat_rate:6’, $chosen_shipping_rates ) ) :
unset( $gateways[‘paypal’] );
unset( $gateways[‘bacs’] );
unset( $gateways[‘transferuj’] );

endif;
if ( in_array( ‘flat_rate:1’, $chosen_shipping_rates ) || in_array( ‘flat_rate:2’, $chosen_shipping_rates )
|| in_array( ‘flat_rate:3’, $chosen_shipping_rates ) || in_array( ‘flat_rate:5’, $chosen_shipping_rates ) ) :

unset( $gateways[‘cod’] );

endif;

return $gateways;
}
add_filter( ‘woocommerce_available_payment_gateways’, ‘my_custom_available_payment_gateways’ );

Can i make it little short?

I’ve been trying a couple of plugins that caused more conflicts than solutions. I am very happy that I stumbled upon your simple code.

I combined your two examples and when customer chooses a courier CoD appears and Pay Locally disappears. If customer chooses local pickup, CoD is gone and Pay locally appears.

Simple and effective. Thank you very much..!!!

Hello and thank you for a great post,

I’ve been using the above code for months successfully but today, after updating WC to the latest version, I noticed that the menu editor in admin panel stopped working!

I discovered that it had to do with the above code and in my logs I get this errors:

#0: *2967264 FastCGI sent in stderr: “PHP message: PHP Fatal error: Uncaught Error: Call to a member function get() on null in /child-theme-path/functions.php:66

#5 /path/wp-admin/includes/template.php(1170): WC_Admin_Menus->nav_menu_links(NULL, Array)
#6 /var” while reading response header from upstream

If I comment out the code erros are gone and menu editor page displays correctly. Any ideas on this?
