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

Thank you in advance!!

CodePudding user response：

Your code contains some mistakes

• Replace WC()->session->get('shipping_method_0')['rates'] with WC()->session->get( 'shipping_for_package_0')['rates']
• Replace if($rate->method_id == 'free_shipping30'){ with if ( $rate->method_id == 'free_shipping' ) {

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 );
