取数组的值（attribute_pa_seat-cover = back）

Question

您好我想获取attribute_pa_seat_cover的值，所以请帮助我。 目前我是$ values，其中包含以下所有数组列表。目前我正在编写下面的代码，它显示了数组的下面细节。 的print_r（$值）;

Array
    (
        [product_id] => 393
        [variation_id] => 424
        [variation] => Array
            (
                [pa_seat-cover] => back
            )

        [quantity] => 4
        [data] => WC_Product_Variation Object
            (
                [variation_id] => 424
                [parent] => WC_Product_Variable Object
                    (
                        [children] => 
                        [total_stock] => 
                        [id] => 393
                        [post] => WP_Post Object
                            (
                                [ID] => 393
                                [post_author] => 1
                                [post_date] => 2014-02-02 01:13:10
                                [post_date_gmt] => 2014-02-02 01:13:10
                                [post_content] => Please contact in store for information and ordering
                                [post_title] => POSITANO
                                [post_excerpt] => 
                                [post_status] => publish
                                [comment_status] => open
                                [ping_status] => closed
                                [post_password] => 
                                [post_name] => positano
                                [to_ping] => 
                                [pinged] => 
                                [post_modified] => 2014-02-13 13:44:56
                                [post_modified_gmt] => 2014-02-13 13:44:56
                                [post_content_filtered] => 
                                [post_parent] => 0
                                [guid] => http://localhost/thecanvas?post_type=product&p=393
                                [menu_order] => 0
                                [post_type] => product
                                [post_mime_type] => 
                                [comment_count] => 0
                                [filter] => raw
                                [format_content] => 
                            )

                        [product_type] => variable
                    )

                [variation_data] => Array
                    (
                        [attribute_pa_seat-cover] => back
                    )

你可以尝试这作为最后一击吗？

您的[data] => WC_Product_Variation Object是一个对象，因此应使用->运算符进行访问，其他运算符只是普通数组。

print $values['data']->variation_data['attribute_pa_seat-cover'];
