Php 根据未用于变体的产品属性隐藏WooCommerce发货方式

对于不在变体中使用的产品属性，当购物车项目是产品变体时，您需要首先获取父变量产品.

然后，您可以使用两种方法:

1. 使用WC_Product get_attributes()方法(the more secure way):

add_filter( 'woocommerce_package_rates', 'hide_shipping_method_based_on_product_attribute', 10, 2 );
function hide_shipping_method_based_on_product_attribute( $rates, $package ) {
    // Product Attribute taxonomy (start always with "pa_")
    $taxonomy = 'pa_season'; // Example for "Season"

    // Array of Shipping method rate ID and term(s) slug(s) pairs
    $data_array = array(
        'free_shipping:8' => array('s24'),
        'flat_rate:17'    => array('f23'),
    );

    // Loop through items in the current shipping package
    foreach( $package['contents'] as $item ){
        // Get the parent variable product if it's a product variation
        $product = $item['variation_id'] > 0 ? wc_get_product($item['product_id']) : $item['data'];
            
        // Loop through our data array
        foreach( $data_array as $rate_id => $term_slugs ) {
            // loop through product attributes
            foreach($product->get_attributes() as $attribute ) {
                if( $attribute->get_taxonomy() === $taxonomy && isset($rates[$rate_id]) 
                && count( array_intersect($attribute->get_slugs(), $term_slugs) ) > 0 ) {
                    unset($rates[$rate_id]);
                }
            }
        }
    }
    return $rates;
}

代码位于您的子主题的unctions.php文件中(或在插件中).应该能行得通.

2. 使用WC_Product get_attribute( $attribute )方法，(where 102 can be the attribute taxonomy or the attribute label name):

因为方法get_attribute()总是返回产品term(s) name(s)的string，所以我们将使用它only when the targeted attribute has a unique term设置在产品中.

然后在下面的代码中，我们将使用术语名称而不是术语slug:

add_filter( 'woocommerce_package_rates', 'hide_shipping_method_based_on_product_attribute', 10, 2 );
function hide_shipping_method_based_on_product_attribute( $rates, $package ) {
    // Product Attribute taxonomy (start always with "pa_")
    $taxonomy = 'pa_season'; // Example for "Season"

    // Array of Shipping method rate ID and term(s) NAME(s) pairs
    $data_array = array(
        'free_shipping:8' => array('S24'),
        'flat_rate:17'    => array('F23'),
    );

    // Loop through items in the current shipping package
    foreach( $package['contents'] as $item ){
        // Get the parent variable product if it's a product variation
        $product = $item['variation_id'] > 0 ? wc_get_product($item['product_id']) : $item['data'];
            
        // Loop through our data array
        foreach( $data_array as $rate_id => $term_names ) {
            if( in_array($product->get_attribute($taxonomy), $term_names) && isset($rates[$rate_id]) ) {
                unset($rates[$rate_id]);
            }
        }
    }
    return $rates;
}

代码位于您的子主题的unctions.php文件中(或在插件中).应该能行得通.
