[FIXED] Reset previous chosen shipping method in Woocommerce checkout page

Issue

Currently, I am clearing the default shipping selection method using this filter:

add_filter( 'woocommerce_shipping_chosen_method', '__return_false', 99);

However, this only clears it during the initial session of the customer. Once the customer chooses an option even once, it remembers the selection for the future.

I am trying to get the checkout to force the customer to pick a shipping option every time they visit the checkout even in the same session. Is it possible to run this filter every time the checkout page is loaded?

Solution

You can reset the last chosen shipping method using in checkout page (for logged in customers):

 delete_user_meta( get_current_user_id(), 'shipping_method' );

And also remove the chosen shipping method from session data:

WC()->session->__unset( 'chosen_shipping_methods' );

In a hooked function like:

add_action( 'template_redirect', 'reset_previous_chosen_shipping_method' );
function reset_previous_chosen_shipping_method() {
    if( is_checkout() && ! is_wc_endpoint_url() && is_user_logged_in() 
    && get_user_meta( get_current_user_id(), 'shipping_method', true ) ) {
        delete_user_meta( get_current_user_id(), 'shipping_method' );
        WC()->session->__unset( 'chosen_shipping_methods' );
    }
}

Or you can also set a default shipping method for everybody in checkout page:

add_action( 'template_redirect', 'reset_previous_chosen_shipping_method' );
function reset_previous_chosen_shipping_method() {
    if( is_checkout() && ! is_wc_endpoint_url() && is_user_logged_in() ) {
        WC()->session->set( 'chosen_shipping_methods', array('flat_rate:14') );
    }
}

To find out the shipping methods rate Ids to be used, you can inspect the shipping method radio buttons in cart or checkout pages, with your browser inspector like:

Code goes on function.php file of your active child theme (or active theme). It should works.
