Php 在WooCommerce中通过Google API计算距离运输车费用

谷歌地图API距离矩阵
计算供应商所在地(billing_city
)与客户所在区域之间的距离,从而向购物车中添加费用。在这里,我使用帐单后的下拉列表表单来获取客户区域
我在从cookies获取值并将变量传递给下一个函数时遇到问题。FYKI,我已将此代码插入到我的子主题函数中
add_action( 'wp_footer', 'calculate_distance_between_two_locations' );
function calculate_distance_between_two_locations($dist) {
// I am getting first item of the cart
foreach( WC()->cart->get_cart() as $cart_item ){
$product_id = $cart_item['product_id'];
break;
}
//Now I am fetching vendor's id and location of the item
$vendor_id = get_post_field( 'post_author', $product_id );
$vendor_location = get_user_meta($vendor_id, 'billing_city', true);
//Here I'm fetching the value from customer location
//I am using a dropdown/select named billing_myfield5
if (is_checkout()) {?>
<script type="text/javascript">
jQuery( document ).ready(function( $ ) {
$('#billing_myfield5').change(function(){
jQuery('body').trigger('update_checkout');
var location = $('#billing_myfield5 option:selected').text();
document.cookie="cusarea="+location;
});
});
</script>
<?php
}
//Encoding the customer's location for Google API
//and putting it into a variable
$customer_area = rawurlencode($_COOKIE ['cusarea']);
//I am setting Google API
$shippingurl = "https://maps.googleapis.com/maps/api/distancematrix/json?origins=".$vendor_location."&destinations=".$customer_area."&key=MY_API_KEY";
//Now fetching json response from googleapis.com:
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $shippingurl);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$response = json_decode(curl_exec($ch), true);
//If google responds with a status of OK
//Extract the distance text:
if($response['status'] == "OK"){
$dist = $response['rows'][0]['elements'][0]['distance']['text'];
}
//Getting the integers from the string
$dist_ance = preg_replace("/[^0-9\.]/", '', $dist);
//Finally putting the value in session
session_start();
$_SESSION['dist'] = $dist_ance;
}
嗯,实际上我有两个问题。任何帮助都将不胜感激
- 有时我从cookie中得到值,有时我没有。我用回声 检查它是否给了我值
- 会话没有响应。我的购物车中的费用为“0”
FYKI,我现在只是想在购物车中只显示数字距离作为费用 以下是在
woocommerce\u cart\u calculate\u fees
操作挂钩中获取所选位置值的正确方法。我已经移动了这个挂钩函数中的所有php代码
在签出表单操作钩子后的一个自定义函数中,我添加了修改后的jQuery代码
我已经测试了一切(但没有谷歌API部分和距离计算费用),它可以实时工作:每次选择一个值,它都会在费用函数中更新
代码如下:

非常感谢。太棒了!我真的很感谢您为使其工作所做的努力:)在woocommerce最近更新后,此代码出现问题。您能帮忙吗?在Skype上敲了你一下。提前谢谢。
