从 Woocommerce 中可变产品的变体中获取产品属性标签

Question

我创建了一个示例 'woocommerce' 产品列表，然后单个产品页面没有获取产品的属性标签。下面显示代码

<?php if ( !$product->variations ) {return;}$field_name = isset($field_name) ? $field_name :'';$calendar_id = isset($calendar_id) ? $calendar_id : 0; <?php if ( $field_name ):?><?php foreach($product->variations as $variation_id => $variation_data):?><?php echo $variation_data['variation_title'];?><?php endforeach ?>

变量$field_name 和$calendar_id 没有在你的代码中定义，所以我不使用它们。

自 Woocommerce 3 以来，您的代码似乎已经过时。从可变产品对象中，要获取变体属性标签名称/术语名称对，请使用以下内容：

<?php 
if ( $product->is_type('variable') && $variations = $product->get_available_variations() ) {
    $field_name  = isset($field_name)  ? $field_name  : '';
    $calendar_id = isset($calendar_id) ? $calendar_id :  0;

    if ( sizeof( $variations ) > 0 ) {

        // Loop through available product variations
        foreach( $variations as $variation ) {

            // Get variation title
            $variation_title = get_the_title( $variation['variation_id'] );

            // Display variation title
            echo '<p><strong>Title:</strong> ' . $variation_title . '</p>';

            // Loop through variation attributtes
            foreach( $variation['attributes'] as $variation_attribute => $term_slug ){
                // Get attribute taxonomy name
                $taxonomy   = str_replace( 'attribute_', '', $variation_attribute );

                // Get attribute label name
                $label_name = wc_attribute_label($taxonomy);
                // Get attribute term name value
                $term_name  = get_term_by( 'slug', $term_slug, $taxonomy )->name;

                // Display attribute label / term name pairs
                echo '<p><strong>' . $label_name . ':</strong> ' . $term_name . '</p>';
            }
        }
    }
}
?>
