如何在 woocommerce 中找到最便宜的运输方式并更改运输标签？

Question

所以这就是我需要做的：找出最便宜的运输方式并将“免费送货”方式标签更改为“免费送货”+“最便宜的方式标签”。这样客户就可以知道免费送货所使用的送货方式。

首先我想到了全局变量。然后使用了 wp_options，但我不确定 wp_options 是用户共享数据还是用户特定数据。

您对以下代码有什么好的想法或更正吗？顺便说一句，这不起作用？谢谢！

add_filter( 'woocommerce_shipping_chosen_method', 'wf_default_shipping_method', 10 );
function wf_default_shipping_method( $method ) {

    $the_cheapest_cost = 1000000;

    $packages = WC()->shipping()->get_packages()[0]['rates'];

    foreach ( array_keys( $packages ) as $key ) {
        
        if ( ( $packages[$key]->cost > 0 ) && ( $packages[$key]->cost < $the_cheapest_cost ) ) {
            $the_cheapest_cost = $packages[$key]->cost;
            $transport_label   = $packages[$key]->label;    
            $method_id         = $packages[$key]->id;
        }
    }

    if(get_option('atransport')){
        update_option('atransport', $transport_label);
    }else{
        add_option('atransport', $transport_label);
    }

    return $method_id;

}  

add_filter( 'woocommerce_package_rates', 'change_shipping_methods_label_names', 20, 2 ); 
function change_shipping_methods_label_names( $rates, $package ) {

    $transport = get_option('atransport');
    foreach( $rates as $rate_key => $rate ) {
        if ( __( 'Free Shipping', 'woocommerce' ) == $rate->label ){ 
            $rates[$rate_key]->label = __( 'FreeShipping -' . $transport, 'woocommerce' ); // New label name
        }
    }
    delete_option('atransport');
    return $rates;
    
}

您可以迭代$rates 的循环并获得最便宜的方法。然后根据找到的最便宜的方法，您可以更改标签。代码将进入您的活动主题 functions.php 文件。

add_filter( 'woocommerce_package_rates', 'hide_other_shipping_when_free_is_available', 100, 1 );
function hide_other_shipping_when_free_is_available( $rates ) {

    $cheapest_method = '';

    // Loop through shipping rates
    if ( is_array( $rates ) ) {
        foreach ( $rates as $key => $rate ) {
            // Set variables when the rate is cheaper than the one saved
            if ( empty( $cheapest_method ) || $rate->cost < $cheapest_method->cost ) {
                $cheapest_method = $rate;
            }
        }
    }

    // Return the cheapest rate when possible
    if ( ! empty( $cheapest_method ) ) {

        $free = array();
        foreach ( $rates as $rate_id => $rate ) {
            if ( $rate->id === $cheapest_method->id ) {

                if ( __( 'Free Shipping', 'woocommerce' ) == $rate->label ){

                    $rates[ $rate_id ] = $rate;
                    // Here we append the labbelled saved price formated display
                    $rates[ $rate_id ]->label = 'Free Shipping '.$rates[ $rate_id ]->label;

                    break; // stop the loop
                }
            }
        }
        return  $rates;
    }

    return  $rates;

}
