使用 WooCommerce 检索产品属性数据和值 API

Question

我正在尝试使用此检索 WooCommerce 产品的产品属性：

$m = get_post_meta($pid, '_product_attributes', false);

其中 $pid 是我的产品 ID。

它部分起作用，但它没有 return 属性值。我在 wp-admin 上设置了尺寸和颜色...

[pa_size] => Array
    (
        [name] => pa_size
        [value] =>
        [position] => 0
        [is_visible] => 1
        [is_variation] => 1
        [is_taxonomy] => 1
    )

[pa_color] => Array
    (
        [name] => pa_color
        [value] =>
        [position] => 1
        [is_visible] => 1
        [is_variation] => 1
        [is_taxonomy] => 1
    )

有什么想法吗？

从 WooCommerce 3 开始，您应该更好地使用 WC_Product 方法 get_attributes()，如下所示：

$product    = wc_get_product( $pid ); // get an instance of the WC_Product Object
$attributes = $product->get_attributes(); // Get an array of WC_Product_Attribute Objects

// Loop through product WC_Product_Attribute objects
foreach ( $attributes as $name => $values ) {
    $label_name       = wc_attribute_label($values->get_name()); // Get product attribute label name

    $data             = $values->get_data(); // Unprotect attribute data in an array

    $is_for_variation = $data['is_variation']; // Is it used for variation
    $is_visible       = $data['is_visible']; // Is it visible on product page
    $is_taxonomy      = $data['is_taxonomy']; // Is it a custom attribute or a taxonomy attribute


    $option_values    = array(); // Initializing

    // For taxonomy product attribute values
    if( $is_taxonomy ) {
        $terms = $values->get_terms(); // Get attribute WP_Terms

        // Loop through attribute WP_Term
        foreach ( $terms as $term ) {
            $term_name     = $term->name; // get the term name
            $option_values[] = $term_name;
        }
    }
    // For "custom" product attributes values
    else {
        // Loop through attribute option values
        foreach ( $values->get_options() as $term_name ) {
            $option_values[] = $term_name;
        }
    }

    // Output for testing
    echo '<strong>' . $label_name . '</strong>:
    <ul><li>' . implode('</li><li>', $option_values) . '</li><br>';
}

已测试并有效。
