wordpress - WooCommerce REST API : query products by multiple attributes

Question

根据 API:http://woocommerce.github.io/woocommerce-rest-api-docs/#list-all-products我们可以按单个属性过滤产品。但是是不是不能通过API进行多属性搜索呢？

示例:“我想要红色 衬衫”。这里的属性是color，属性术语是red。要完成搜索，查询字符串如下所示:products?category=17&attribute=pa_color&attribute_term=22&

而且我们只得到红色衬衫。

但对于“我想要red medium shirts”，这里有一个额外的size属性，值为medium遭遇。根据 API，无法在查询字符串中关联 color 和 size 属性。所以查询 -

products?category=17&attribute=pa_color&attribute_term=22&attribute=pa_size&attribute_term=24& 

从商店退回所有产品

有什么解决方法吗？

我已经编写了可以完成这一切的自定义查询:D这是一个回调函数。您需要做的就是使用此回调创建新端点:

这是一个文档:

category - string (category slug) - filter by products category.
per_page - int (default - from admin) - show items on one page.
offset - int (default - 1) - show page number.
order - string (ASC/DESC, default: desc) - order products ascending or descending.
orderby - string (name, price, default: name) - order products by key.
filter - array
[pa_attribute_name (string) ]  = array of ID's.
[min_price (string) ] = int.
[max_price (string) ] = int.

示例:

/wp-json/go/v1/products/?category=smartphones&filter[pa_brand]=87,88&filter[pa_colour]=17&filter[min_price]=1&filter[max_price]=50&per_page=10&offset=1&order=DESC&orderby=price

这是一个函数:

public function get_products_list_callback( \WP_REST_Request $request ) {
    $params = $request->get_params();

    $category = General_Helper::get_array_value( 'category', $params );
    $filters  = General_Helper::get_array_value( 'filter', $params );
    $per_page = General_Helper::get_array_value( 'per_page', $params );
    $offset   = General_Helper::get_array_value( 'offset', $params );
    $order    = General_Helper::get_array_value( 'order', $params );
    $orderby  = General_Helper::get_array_value( 'orderby', $params );

    $output = [];

    // Use default arguments.
    $args = [
      'post_type'      => Config::POST_TYPE_SLUG_PRODUCT,
      'posts_per_page' => get_option( 'posts_per_page' ),
      'post_status'    => 'publish',
      'paged'          => 1,
    ];

    // Posts per page.
    if ( ! empty( $per_page ) ) {
      $args['posts_per_page'] = $per_page;
    }

    // Pagination, starts from 1.
    if ( ! empty( $offset ) ) {
      $args['paged'] = $offset;
    }

    // Order condition. ASC/DESC.
    if ( ! empty( $order ) ) {
      $args['order'] = $order;
    }

    // Orderby condition. Name/Price.
    if ( ! empty( $orderby ) ) {
      if ( $orderby === 'price' ) {
        $args['orderby'] = 'meta_value_num';
      } else {
        $args['orderby'] = $orderby;
      }
    }

    // If filter buy category or attributes.
    if ( ! empty( $category ) || ! empty( $filters ) ) {
      $args['tax_query']['relation'] = 'AND';

      // Category filter.
      if ( ! empty( $category ) ) {
        $args['tax_query'][] = [
          'taxonomy' => Config::TAXONOMY_SLUG_PRODUCT,
          'field'    => 'slug',
          'terms'    => [ $category ],
        ];
      }

      // Attributes filter.
      if ( ! empty( $filters ) ) {
        foreach ( $filters as $filter_key => $filter_value ) {
          if ( $filter_key === 'min_price' || $filter_key === 'max_price' ) {
            continue;
          }

          $args['tax_query'][] = [
            'taxonomy' => $filter_key,
            'field'    => 'term_id',
            'terms'    => \explode( ',', $filter_value ),
          ];
        }
      }

      // Min / Max price filter.
      if ( isset( $filters['min_price'] ) || isset( $filters['max_price'] ) ) {
        $price_request = [];

        if ( isset( $filters['min_price'] ) ) {
          $price_request['min_price'] = $filters['min_price'];
        }

        if ( isset( $filters['max_price'] ) ) {
          $price_request['max_price'] = $filters['max_price'];
        }

        $args['meta_query'][] = \wc_get_min_max_price_meta_query( $price_request );
      }
    }

    $the_query = new \WP_Query( $args );

    if ( ! $the_query->have_posts() ) {
      return $output;
    }

    while ( $the_query->have_posts() ) {
      $the_query->the_post();

      $output[] = get_the_title();
    }
    wp_reset_postdata();

    return $output;
  }
