刷新城市选择字段的运费

Question

我正在尝试更新/刷新城市变化的运费，到目前为止，我只能通过手动刷新页面来做到这一点。

add_action( 'woocommerce_package_rates', 'check_minimum_and_city', 10, 2 );
function check_minimum_and_city($rates, $package){
    $selected_city = WC()->checkout->get_value('billing_city');
    $price_thirty = array('bat-yam','hulon','azur','tel-aviv-yafo','givatayim','ramat-gan','bnei-brak','rishon-letzion','netaim','yavne','kfar-nagid','galiya','ben-zakai','beit-gamliel');
    $price_fifty = array('einot','gan-shlomo','beit-oved','aseret','givat-brener','irus','misgav-dov','givton','kerem-yavne','beit-raban','rehovot','beit-elezri','beit-hanan','kvuzat-yavne','kfar-bilu','bnei-darom','nir-galim','kiryat-ekron','gedera','nes-tziona','kanot','gan-darom','netayim','mishmar-hashiva','gan-sorek','beit-dagan','ganot','beit-hanan-irus','hemed');
    $price_sixty = array('savion','ganei-tikva','or-yehuda','kiryat-ono','yehud','petah-tikva','ramat-hasharon','herzliya','kfar-shmariyahu','rishpon','raanana','kfar-saba','tsafria','beer-yaakov','netser-sireni','nir-tzvi','ramla','matsliax','bnaya','kfar-aviv');
    if(WC()->session->get( 'chosen_shipping_methods' )[0] == 'local_pickup:13'){            
        $minimum = 0;       
    }else{      
        $minimum_thirty = 100;
        $minimum_fifty = 150;
        $minimum_sixty = 200;
        if(in_array($selected_city, $price_thirty)){
            unset( $rates['flat_rate:18']);
            unset( $rates['flat_rate:19']);
            if(WC()->cart->subtotal < $minimum_thirty){
                throw new Exception( 
                    sprintf( 'סכום ההזמנה הנוכחית שלך עומד על %s, מינימום הזמנה לפני משלוח הינו %s.' , 
                        wc_price( WC()->cart->subtotal ),
                        wc_price( $minimum_thirty )
                    )
                );  
            }           
        }elseif(in_array($selected_city, $price_fifty)){
            unset( $rates['flat_rate:9']);
            unset( $rates['flat_rate:19']);
            if(WC()->cart->subtotal < $minimum_fifty){
                throw new Exception( 
                    sprintf( 'סכום ההזמנה הנוכחית שלך עומד על %s, מינימום הזמנה לפני משלוח הינו %s.' , 
                        wc_price( WC()->cart->subtotal ),
                        wc_price( $minimum_fifty )
                    )
                );
            }
        }elseif(in_array($selected_city, $price_sixty)){
            unset( $rates['flat_rate:9']);
            unset( $rates['flat_rate:18']);
            if(WC()->cart->subtotal < $minimum_sixty){
                throw new Exception( 
                    sprintf( 'סכום ההזמנה הנוכחית שלך עומד על %s, מינימום הזמנה לפני משלוח הינו %s.' , 
                        wc_price( WC()->cart->subtotal ),
                        wc_price( $minimum_sixty )
                    )
                );
            }
        }       
        return $rates;
    }   
}

当我选择一个城市字段（下拉自定义列表）时，我会通过 woocommerce 设置获得运费，但是当我更改它时，它不会更新费率。

add_filter( 'woocommerce_checkout_fields', 'city_dropdown_field' );
function city_dropdown_field( $fields ) {

    $city_args = wp_parse_args( array(

    $fields['shipping']['shipping_city'] = $city_args;
    $fields['billing']['billing_city'] = $city_args;

    return $fields;

}

尝试使用这个 jQuery，但没有任何效果

add_action( 'wp_footer', 'checkout_shipping_city_refresh_display' );
function checkout_shipping_city_refresh_display() {
    // On checkout
    if ( is_checkout() && ! is_wc_endpoint_url() ) :
    ?><script type="text/javascript">
    jQuery( function($){
        // Shipping fias code change & input events
        $(document.body).on( 'change', 'select[name=billing_city]', function() {
            console.log($(this).val());
        });
    });
    </script>
    <?php
    endif;
}

感谢您的帮助。 :-)

我已经设法解决了这个问题，这是我的解决方案，答案是在更正的 AJAX 调用中，从多个运费更改为一个，并通过代码更改费率。

add_action('woocommerce_checkout_update_order_review', 'refresh_shipping_methods', 10, 1 );
function refresh_shipping_methods( $post_data ){    
    WC()->cart->calculate_shipping();
}

add_action( 'wp_footer', 'checkout_shipping_city_refresh_display' );
function checkout_shipping_city_refresh_display() {
    // On checkout
    if ( is_checkout() && ! is_wc_endpoint_url() ) :
    ?><script type="text/javascript">

    jQuery(document).on('change', 'select[name=billing_city]', function(){
         var requested_city = jQuery(this).val();
         ajaxurl = '<?php echo admin_url( 'admin-ajax.php' ) ?>'; // get ajaxurl

            var data = {
                    'action': 'get_and_set_shipping_rate',
                    'city': requested_city
                };
    
                jQuery.ajax({
                    type: "POST",
                    url: ajaxurl, // this will point to admin-ajax.php
                    data: data,
                    async: false,
