在 woocommerce（wordpress）中结帐时无法更新运费

Question

我正在尝试使用自定义插件代码将运费添加到当前订单中。我已经编写了一个插件来显示一些用于交付选项和取件选项的单选按钮，并为单选检查事件嵌入一个 javascript 文件。以下是我的插件代码：

if ( in_array( 'woocommerce/woocommerce.php', apply_filters( 'active_plugins', get_option( 'active_plugins' ) ) ) ) {

function radio_button_checks(){
wp_register_script('wp_head',plugin_dir_url(__FILE__).'radio_check.js',array( 'jquery' ), '1.0', true);
wp_enqueue_script('wp_head');
}
function delivery_form() {

$content = '<div style="width:90%; margin-top:10px; float:left; background-color:rgba(255, 255, 255, 0.85); border-radius:5px; padding:5%;">';
$content .= '<h3 id="first-self-id"><input type="radio" value="self_product_pick_up" class="distance_between_text" name="delivery" id="self-delivery" />PICK UP AT THE TROPICAL FRUIT TRIBE HQ KICTHEN AT 1/1 GENERAL BRIDGES CREC, DACEYVILLE 2032</h2>';
$content .= '<div id="self-delivery-functionality" class="delivery_functionality" style="width: 100%; display: inline-block;">';
$content .= '<div class="self_delivery_day" style="width: 45%; float: left; padding: 0% 2%; text-align: right; ">';
$content .= '<h4><input type="radio" value="tuesday" class="distance_between_text" />TUE</h4>';
$content .= '</div>';
$content .= '<div class="self_delivery_time" style="width: 45%; float: left; padding: 0% 2%; text-align: left;">';
$content .= '<h4><input type="radio" name="pickup_time" value="9AM-12PM" class="distance_between_text" />9AM-12PM</h4>';
$content .= '<h4><input type="radio" name="pickup_time" value="12PM-3PM" class="distance_between_text" />12PM-3PM</h4>';
$content .= '<h4><input type="radio" name="pickup_time" value="3PM-6PM" class="distance_between_text" />3PM-6PM</h4>';
$content .= '<h4><input type="radio" name="pickup_time" value="6PM-8PM" class="distance_between_text" />6PM-8PM</h4>';
$content .= '</div>';
$content .= '</div>';
$content .= '<h3 id="second-notSelf-id"><input type="radio" value="shop_keeper_delivery" class="distance_between_text" checked="checked" name="delivery" id="other-one-deliver" />DELIVERY OPTION ( only)</h2>';
$content .= '<div id="seller-delivery-functionality" style="display:block;">';
$content .= '<div class="delivery-info-text" style="text-align: left;">';
$content .= '<p style="margin:5px; font-size:1em;">PLEASE KEEP IN MIND THAT THIS IS A FROZEN PRODUTS AND NEEDS TO BE STORED IN FREEZER IMMEDIATLY UPON DELIVERY. PLEASE ENSURE YOU ARE AVAILABLE TO TAKE THIS DELIVERY AT THE DROP OFF LOCATION SPECIFIED.</p>';
$content .= '</div>';
$content .= '<div class="delivery_functionality" style="width: 100%; display: inline-block;">';
$content .= '<div class="shop_keeper_delivery_day" style="width: 45%; float: left; padding: 0% 2%; text-align: right;">';
$content .= '<h4><input type="radio" name="delivery_day" value="monday" class="distance_between_text" />Mon</h4>';
$content .= '<h4><input type="radio" name="delivery_day" value="fri" class="distance_between_text" />Fri</h4>';
$content .= '</div>';
$content .= '<div class="shop_keeper_delivery_time" style="width: 45%; float: left; padding: 0% 2%; text-align: left;">';
$content .= '<h4><input type="radio" name="delivery_time" value="9AM-12PM" name="" class="distance_between_text" />9AM-12PM</h4>';
$content .= '<h4><input type="radio" name="delivery_time" value="12PM-3PM" class="distance_between_text" />12PM-3PM</h4>';
$content .= '<h4><input type="radio" name="delivery_time" value="3PM-6PM" class="distance_between_text" />3PM-6PM</h4>';
$content .= '<h4><input type="radio" name="delivery_time" value="6PM-8PM" class="distance_between_text" />6PM-8PM</h4>';
$content .= '</div>';
$content .= '</div>';
$content .= '</div>';
$content .= '<input type="hidden" id="shipping_rate" value="0.00" /> ';
$content .= '</div>';
echo $content;  


} 

add_action("woocommerce_after_cart_table","delivery_form");
add_action("wp_enqueue_scripts","radio_button_checks");

和我的 radio_check.js 文件包含以下代码：

jQuery(document).ready(function(){

/* Checkout CheckBox Functionality for Self Delivery */
jQuery("#self-delivery-functionality").hide("slow");
jQuery("#seller-delivery-functionality").show("slow");
jQuery("#self-delivery").click( function() {
    if(jQuery(this).is(':checked')) {
        jQuery("#self-delivery-functionality").show("slow");
        jQuery("#seller-delivery-functionality").hide("slow");
        jQuery("#seller-delivery-functionality").find("input[type='checkbox']").prop("checked", false);
        jQuery("#seller-delivery-functionality").find("input[type='radio']").prop("checked", false);
    }
});

/* Checkout CheckBox Functionality for having Delivery Functionality */
jQuery("#other-one-deliver").click( function() {
    if(jQuery(this).is(':checked')) {
        jQuery("#seller-delivery-functionality").show("slow");
        jQuery("#self-delivery-functionality").hide("slow");
        jQuery("#self-delivery-functionality").find("input[type='checkbox']").prop("checked", false);
        jQuery("#self-delivery-functionality").find("input[type='radio']").prop("checked", false);
    }
});

jQuery('input[name=delivery_time]').click(function(){

    if(jQuery(this).is(':checked')) 
    {

        var curr_amount_dol = jQuery('.cart-subtotal .amount').html().replace('$','');


        var total_amount = parseFloat(curr_amount_dol) +  parseFloat(12.00);
        //alert(total_amount.toFixed(2)); 
        jQuery('#shipping_rate').val('$'+total_amount.toFixed(2));
        jQuery('.order-total .amount').html('$'+total_amount.toFixed(2));

    }

});
}); //ready function ends

此代码正在更新总金额（仅显示）以及运费（即 12 美元），但是当我单击结帐按钮时，我不会在下一页获得总金额和运费。

我还应该在此代码中添加什么以更新选中的单选按钮上的运费？

注意：目前总金额正在通过 javascript 更新。

Answer 1

'woocommerce_cart_calculate_fees' 解决了我的问题。我刚刚添加了以下代码并在 javascript.

上做了一些修改

function woo_add_cart_fee() {
    $req = $_REQUEST['shipping_method'];
    if($req=='delivery')
    {
        WC()->session->set('ship_val','12.00');
    }   
    else if($req=='pickup')
    {
        WC()->session->set('ship_val','00.00');
    }
    //checkship($_REQUEST['shipping_method']);
    WC()->cart->add_fee('Shipping ', WC()->session->get('ship_val'));
}
add_action('woocommerce_cart_calculate_fees', 'woo_add_cart_fee');

并且对于 javascript 我只是重定向同一个页面以及一个查询参数 'shipping_method'

jQuery('input[name=delivery_time]').click(function(){

        if(jQuery(this).is(':checked')) 
        {
         window.location='http://examplesite.com/cart/?shipping_method=delivery';
         }

});

jQuery('input[name=pickup_time]').click(function(){

        if(jQuery(this).is(':checked')) 
        {
   window.location='http://examplesite.com/cart/?shipping_method=pickup[';
         }

});

选中单选按钮后，我的页面被重定向到查询 ?shipping_method=delivery / ?shipping_method=pickup 和我在插件文件中的 php 代码检查参数值并使用以下方法设置运费：

add_action('woocommerce_cart_calculate_fees', 'woo_add_cart_fee');

购物车页面和结帐页面上的费用也会更新。
