Woocommerce：删除未选择的运输方式

Question

我正在尝试根据产品选择设置运输方式，我已经实现了，但我还想隐藏其他运输方式，这样用户就看不到它们，也无法选择它们。这是我正确选择运输方式的代码：

add_action( 'template_redirect', 'nhy_chosen_shipping_methods' );

function nhy_chosen_shipping_methods(){
    remove_action(current_filter(), __FUNCTION__);
    
    $items = WC()->cart->get_cart();
    $max_dimension = 0;
    $final_max = 0;
    foreach( $items as $item => $values ){ 
        $_product =  wc_get_product( $values['data']->get_id());
        if(empty($values['we_custom_dimensions'])){
            $max_dimension = $_product->get_length() >= $_product->get_height() ? $_product->get_length() : $_product->get_height(); 
        }
        else{
            $dims = explode('x', $values['we_custom_dimensions']);
            $max_dimension = $dims[0] >= $dims[1] ? $dims[0] : $dims[1]; 
        }
        if($max_dimension > $final_max){
            $final_max = $max_dimension;
        }
        
    }
    
    if( WC()->cart->cart_contents_total >= 100 ){
        WC()->session->set( 'chosen_shipping_methods', array('free_shipping:10') );
        return;
    }

    
    if($final_max <= 70){
        WC()->session->set( 'chosen_shipping_methods', array('flat_rate:8') );
        return;
    }
    else{ 
        WC()->session->set( 'chosen_shipping_methods', array('flat_rate:9') );
        return;
    }
    
   
}

更新

也许我可以用未选中的 css 隐藏它们？

试试这个钩子 woocommerce_before_checkout_shipping_form

add_action( 'woocommerce_before_checkout_shipping_form', 'nhy_chosen_shipping_methods' );

function nhy_chosen_shipping_methods( $checkout ){
    
    $items = WC()->cart->get_cart();
    $max_dimension = 0;
    $final_max = 0;
    foreach( $items as $item => $values ){ 
        $_product =  wc_get_product( $values['data']->get_id());
        if(empty($values['we_custom_dimensions'])){
            $max_dimension = $_product->get_length() >= $_product->get_height() ? $_product->get_length() : $_product->get_height(); 
        }
        else{
            $dims = explode('x', $values['we_custom_dimensions']);
            $max_dimension = $dims[0] >= $dims[1] ? $dims[0] : $dims[1]; 
        }
        if($max_dimension > $final_max){
            $final_max = $max_dimension;
        }
        
    }
    
    // first unset your methods
    WC()->session->__unset( 'flat_rate:8' );
    WC()->session->__unset( 'flat_rate:9' );
    WC()->session->__unset( 'free_shipping:10' );

    // not set based on your conditions.
    if( WC()->cart->cart_contents_total >= 100 ){
        WC()->session->set( 'chosen_shipping_methods', array('free_shipping:10') );
    }elseif( $final_max <= 70 ){
        WC()->session->set( 'chosen_shipping_methods', array('flat_rate:8') );
    }else{ 
        WC()->session->set( 'chosen_shipping_methods', array('flat_rate:9') );
    }
    
}
