在尝试通过修改来重现此处找到的解决方案 (Sort products by brand and title in Woocommerce) 时,我遇到了一个问题...
按品牌排序的第一种排序效果很好,但我找不到通过提高或降低价格来进行第二种排序的方法。
add_filter('posts_clauses', 'posts_clauses_with_tax', 10, 2);
function posts_clauses_with_tax( $clauses, $wp_query ) {
global $wpdb;
$taxonomies = array('pwb-brand');
$orderBy['field'] = "pwb-brand";
$orderBy['direction'] = "ASC";
if( in_array($orderBy['field'], $taxonomies) ) {
$clauses['join'] .= "
LEFT OUTER JOIN {$wpdb->term_relationships} AS rel2 ON {$wpdb->posts}.ID = rel2.object_id
LEFT OUTER JOIN {$wpdb->term_taxonomy} AS tax2 ON rel2.term_taxonomy_id = tax2.term_taxonomy_id
LEFT OUTER JOIN {$wpdb->terms} USING (term_id)
";
$clauses['where'] .= " AND (taxonomy = '".$orderBy['field']."' OR taxonomy IS NULL)";
$clauses['groupby'] = "rel2.object_id";
$clauses['orderby'] = "GROUP_CONCAT({$wpdb->terms}.slug ORDER BY slug ASC) ";
$clauses['orderby'] .= ", {$wpdb->posts}.post_title ASC";
return $clauses;
}
else {
return $clauses;
}
}
我找到了这些行,但我很难在上面的查询中添加这些行以按价格 ASC 替换 orderby 标题
$clauses['join'] .= " LEFT JOIN {$wpdb->postmeta} price ON( {$wpdb->posts }.ID = price.post_id AND price.meta_key = 'price') ";
$clauses['orderby'] = " CONVERT( REPLACE(price.meta_value, '$', ''), DECIMAL(13,2) ) " . $order;
你知道解决方案吗?
答案 0 :(得分:0)
好的,总是在我们写下问题并开发出答案的时候......
这是使用插件 Perfect Brands for WooCommerce
在您的 WooCommerce 中添加自定义过滤器品牌和价格 ASC 的完整解决方案首先,添加自定义过滤器:
add_filter( 'woocommerce_catalog_orderby', 'my_add_custom_sorting_options' );
add_filter( 'woocommerce_default_catalog_orderby_options', 'my_add_custom_sorting_options' );
function my_add_custom_sorting_options( $options ){
$options['brands'] = __("Tri par marque / prix croissant", "yourdomain");
return $options;
}
然后添加
add_filter( 'woocommerce_get_catalog_ordering_args', 'custom_woocommerce_get_catalog_ordering_args' );
function custom_woocommerce_get_catalog_ordering_args( $args ) {
$orderby_value = isset( $_GET['orderby'] ) ? wc_clean( $_GET['orderby'] ) : apply_filters( 'woocommerce_default_catalog_orderby', get_option( 'woocommerce_default_catalog_orderby' ) );
if ( 'brands' == $orderby_value ) {
add_filter('posts_clauses', 'posts_clauses_brands_price', 10, 2);
}
return $args;
}
终于
function posts_clauses_brands_price( $clauses, $wp_query ) {
global $wpdb;
$taxonomies = array('pwb-brand');
$orderBy['field'] = "pwb-brand";
$orderBy['direction'] = "ASC";
if( in_array($orderBy['field'], $taxonomies) ) {
$clauses['join'] .= " LEFT JOIN {$wpdb->wc_product_meta_lookup} wc_product_meta_lookup ON $wpdb->posts.ID = wc_product_meta_lookup.product_id ";
$clauses['join'] .= "
LEFT OUTER JOIN {$wpdb->term_relationships} AS rel2 ON {$wpdb->posts}.ID = rel2.object_id
LEFT OUTER JOIN {$wpdb->term_taxonomy} AS tax2 ON rel2.term_taxonomy_id = tax2.term_taxonomy_id
LEFT OUTER JOIN {$wpdb->terms} USING (term_id)
";
$clauses['where'] .= " AND (taxonomy = '".$orderBy['field']."' OR taxonomy IS NULL)";
$clauses['groupby'] = "rel2.object_id";
$clauses['orderby'] = "GROUP_CONCAT({$wpdb->terms}.slug ORDER BY slug ASC) ";
$clauses['orderby'] .= ', wc_product_meta_lookup.min_price ASC, wc_product_meta_lookup.product_id ASC ';
return $clauses;
}
else {
return $clauses;
}
}
