Set “flat rate” shipping method as default in woocommerce

问题

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.

Any help should be appreciated.

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).

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. :)

copy the value Id from here
