Question

我今天安装了WooCommerce Brands插件，并注意到一件事，我想对其进行一些修改以使其以我喜欢的方式工作。在左侧栏中按某些品牌过滤器时，将显示该类别的产品品牌。但是，如果从“ Left Brands”窗口小部件上按其他品牌，则会在第二个选择上添加第二个选择，并显示如下所示的URL：

https://www.example.com/product-category/mens/?filtering=1&filter_product_brand=231,229

所以 231 是我点击的第一个品牌，而 229 是第二个点击的品牌，但是我只希望最后一次点击处于活动状态，而不是两个都激活！我检查了他们的documentation，但他们没有提供有关此更改的任何信息。我找到了进行此更改的代码（进入文件 class-wc-widget-brand-nav.php ），似乎是JQ代码：

wc_enqueue_js( "
                jQuery( '.wc-brand-dropdown-layered-nav-". esc_js( $taxonomy ) . "' ).change( function() {
                    var slug = jQuery( this ).val();
                    location.href = '" . preg_replace( '%\/page\/[0-9]+%', '', str_replace( array( '&amp;', '%2C' ), array( '&', ',' ), esc_js( add_query_arg( 'filtering', '1', remove_query_arg( array( 'page', 'filter_' . $taxonomy ) ) ) ) ) ) . "&filter_". esc_js( $taxonomy ) . "=' + jQuery( '.wc-brand-dropdown-layered-nav-" . esc_js( $taxonomy ) . "' ).val();
                });
            " );
        }

        return $found;
    } 

protected function layered_nav_list( $terms, $taxonomy ) {
        // List display
        echo '<ul class="wc-brand-list-layered-nav-' . esc_attr( $taxonomy ) . '">';

        $term_counts        = $this->get_filtered_term_product_counts( wp_list_pluck( $terms, 'term_id' ), $taxonomy );
        $_chosen_attributes = $this->get_chosen_attributes();
        $current_values     = ! empty( $_chosen_attributes ) ? $_chosen_attributes : array();
        $found              = false;

        $filter_name    = 'filter_' . $taxonomy;

        foreach ( $terms as $term ) {
            $option_is_set  = in_array( $term->term_id, $current_values );
            $count          = isset( $term_counts[ $term->term_id ] ) ? $term_counts[ $term->term_id ] : 0;

            // skip the term for the current archive
            if ( $this->get_current_term_id() === $term->term_id ) {
                continue;
            }

            // Only show options with count > 0
            if ( 0 < $count ) {
                $found = true;
            } elseif ( 0 === $count && ! $option_is_set ) {
                continue;
            }

            $current_filter = isset( $_GET[ $filter_name ] ) ? explode( ',', wc_clean( $_GET[ $filter_name ] ) ) : array();
            $current_filter = array_map( 'intval', $current_filter );

            if ( ! in_array( $term->term_id, $current_filter ) ) {
                $current_filter[] = $term->term_id;
            }

            $link = $this->get_page_base_url( $taxonomy );

            // Add current filters to URL.
            foreach ( $current_filter as $key => $value ) {
                // Exclude query arg for current term archive term
                if ( $value === $this->get_current_term_id() ) {
                    unset( $current_filter[ $key ] );
                }

                // Exclude self so filter can be unset on click.
                if ( $option_is_set && $value === $term->term_id ) {
                    unset( $current_filter[ $key ] );
                }
            }

            if ( ! empty( $current_filter ) ) {
                $link = add_query_arg( array( 'filtering' => '1', $filter_name => implode( ',', $current_filter ) ), $link );
            }

            echo '<li class="wc-layered-nav-term ' . ( $option_is_set ? 'chosen' : '' ) . '">';

            echo ( $count > 0 || $option_is_set ) ? '<a href="' . esc_url( apply_filters( 'woocommerce_layered_nav_link', $link ) ) . '">' : '<span>';

            echo esc_html( $term->name );

            echo ( $count > 0 || $option_is_set ) ? '</a> ' : '</span> ';

            echo apply_filters( 'woocommerce_layered_nav_count', '<span class="count">(' . absint( $count ) . ')</span>', $count, $term );

            echo '</li>';
        }

        echo '</ul>';

        return $found;
    }

但我认为必须在此处进行更改：

wc_enqueue_js( "
                jQuery( '.wc-brand-dropdown-layered-nav-". esc_js( $taxonomy ) . "' ).change( function() {
                    var slug = jQuery( this ).val();
                    location.href = '" . preg_replace( '%\/page\/[0-9]+%', '', str_replace( array( '&amp;', '%2C' ), array( '&', ',' ), esc_js( add_query_arg( 'filtering', '1', remove_query_arg( array( 'page', 'filter_' . $taxonomy ) ) ) ) ) ) . "&filter_". esc_js( $taxonomy ) . "=' + jQuery( '.wc-brand-dropdown-layered-nav-" . esc_js( $taxonomy ) . "' ).val();
                });
            " );
        }

        return $found;
    } 

 // All current filters
        if ( $_chosen_attributes = WC_Query::get_layered_nav_chosen_attributes() ) {
            foreach ( $_chosen_attributes as $name => $data ) {
                if ( $name === $taxonomy ) {
                    continue;
                }
                $filter_name = sanitize_title( str_replace( 'pa_', '', $name ) );
                if ( ! empty( $data['terms'] ) ) {
                    $link = add_query_arg( 'filter_' . $filter_name, implode( ',', $data['terms'] ), $link );
                }
                if ( 'or' == $data['query_type'] ) {
                    $link = add_query_arg( 'query_type_' . $filter_name, 'or', $link );
                }
            }
        }

        return $link;
    }

这是实时example，存在问题。所以我的问题是，如何仅保留一个品牌选择器？

限制筛选器以仅显示最后选择的品牌-WooCommerce品牌
