如果语句里面的开关（PHP）

Question

I'm working with WooCommerce and I am trying to develop a way to perform price calculation based in two factors:

• location of the customer by city
• category

I was able to change price based on the location of the customer but if I try to filter by location and category at the same time it does not work. To perform the filter by category I add this if statement:

if( has_term( array('nike'), 'product_cat' ,$product->ID) )

But I don't understand why this does not work.

Here is the code:

$userInfo = geoip_detect2_get_info_from_current_ip();
$countryCode = $userInfo->city->name;

switch ($countryCode) {
    case 'Madrid':
        if (has_term(array('nike') , 'product_cat', $product->ID)) {
            add_filter('woocommerce_get_price', 'product_custom_price', 10, 2);
            function product_custom_price($price, $product) {
                $custom_price = $product->get_regular_price();
                return $custom_price * 1.5;
            }
        }

        break;

    case 'Barcelona':
        if (has_term(array('adidas') , 'product_cat', $product->ID)) {
            add_filter('woocommerce_get_price', 'product_custom_price', 10, 2);
            function product_custom_price($price, $product) {
                $custom_price = $product->get_regular_price();
                return $custom_price * 1.25;
            }
        }

        break;
}

You are using has_term in wrong way and you can use foreach instead

Try this:

 $userInfo = geoip_detect2_get_info_from_current_ip();
    $countryCode = $userInfo->city->name;
    $terms = get_the_terms($product->ID, 'product_cat');
                switch ($countryCode) {
                case 'Madrid':
          foreach ( $terms as $term ) {
            if($term->name == 'nike') {
                   add_filter('woocommerce_get_price', 'product_custom_price', 10, 2);
                   function product_custom_price($price, $product) {
                 $custom_price = $product->get_regular_price();
                 return $custom_price * 1.5;}
                                }
                    }

                break;
                case 'Barcelona':

           foreach ( $terms as $term ) {
               if($term->name == 'adidas') {
                   add_filter('woocommerce_get_price', 'product_custom_price', 10, 2);
                    function product_custom_price($price, $product) {
                     $custom_price = $product->get_regular_price();
                      return $custom_price * 1.25;}
                                    }
                    }        

                break;

}
