Set "free shipping" method as selected default shipping option in WooCommerce

I'm struggling with changing the shipping option selected default. The 'Free shipping' shipping option only shows up if the customer has the amount over $70 + in the cart. If the amount on the cart is less than $70 the shipping option will not show up on the shipping options.

If the customer has over $70 or more, the "Free shipping" option will show up and it should be a default selected shipping option.

I tried adding the following snippet but it seems not working for me or maybe there's a mistake on modifying the ID's(unsure).

add_action( 'woocommerce_before_cart', 'set_default_chosen_shipping_method', 5 );
function set_default_chosen_shipping_method(){
    //
    if( count( WC()->session->get('shipping_method_0')['rates'] ) > 0 ){
        foreach( WC()->session->get('shipping_method_0')['rates'] as $rate_id =>$rate)
            if($rate->method_id == 'free_shipping30'){
                $default_rate_id = array( $rate_id );
                break;
            }

        WC()->session->set('chosen_shipping_methods', $default_rate_id );
    }
}

I got this snippet idea here

Solution

  • Your code contains some mistakes

    So you get:

    function action_woocommerce_before_cart() { 
    // NOT empty (get)
    if ( count( WC()->session->get( 'shipping_for_package_0')['rates'] ) > 0 ) {
        // Loop through
        foreach ( WC()->session->get('shipping_for_package_0')['rates'] as $rate_id => $rate ) {            
            // For free shipping
            if ( $rate->method_id == 'free_shipping' ) {
                $default_rate_id = array( $rate_id );
                break;
            }
        }

        // Set
        WC()->session->set( 'chosen_shipping_methods', $default_rate_id );
    }
}
add_action( 'woocommerce_before_cart', 'action_woocommerce_before_cart', 10, 0 );
