Set "flat rate" shipping method as default in woocommerce - php

Question

I have a woocommerce website and I have set 2 shipping methods:
Flat Rate
Local pickup
I would like to set the "Flat rate" shipping method as default (selected) in the cart or checkout page.

Answer 1

1) You can use the following code (to set "flat rate" shipping method as default) In cart page:
add_action( 'woocommerce_before_cart', 'set_default_chosen_shipping_method', 5 );
function set_default_chosen_shipping_method(){
//
if( count( WC()->session->get('shipping_for_package_0')['rates'] ) > 0 ){
foreach( WC()->session->get('shipping_for_package_0')['rates'] as $rate_id =>$rate)
if($rate->method_id == 'flat_rate'){
$default_rate_id = array( $rate_id );
break;
}
WC()->session->set('chosen_shipping_methods', $default_rate_id );
}
}
Code goes in function.php file of your active child theme (active theme or in any plugin file).
Tested and Works in WooCommerce 3+
2) You can also reorder the shipping rates in your shipping zones settings (but it doesn't really works as the last chosen shipping method take the hand).

Answer 2

You could use the following code to set 'any' shipping method as default.
function reset_default_shipping_method( $method, $available_methods ) {
$default_method = 'wf_fedex_woocommerce_shipping:FEDEX_GROUND'; //provide the service name here
if( array_key_exists($method, $available_methods ) )
return $default_method;
else
return $method;
}
Let's say, you're using a Carrier shipping plugin like WooCommerce FedEx Shipping Plugin. You can fetch the value Id (shown below) and paste it under the '$default_method' in the above code.
You will have to copy and paste the code in WordPress Dashboard->Appearance–>Editor–>functions.php of your theme.
Hope that helped. :)
