我想要的:修改WooCommerce搜索表单的查询(在前端),通过搜索产品的名称、说明和产品标签来显示产品。
我所拥有的:我正在尝试从这个答案中获得灵感的代码,该答案返回产品名称和描述的结果。但是如果我用标签名称搜索,没有结果。搜索查询不搜索产品的标签。
如何重现这个问题(把下面的代码放在functions.php活动主题的文件中):
function search_product_by_tag( $search, &$query_vars ) {
global $wpdb, $pagenow;
if ( 'edit.php' == $pagenow || empty($search) ) {
return $search;
}
$args = array(
'posts_per_page' => -1,
'post_type' => 'product',
'meta_query' => array(
array(
'key' => 'taxonomy',
'value' => 'product_tag',
'field' => 'name',
'terms' => array($query_vars->query['s']),
'compare' => 'LIKE',
)));
$posts = get_posts( $args );
if ( empty( $posts ) ) return $search;
$get_post_ids = array();
foreach($posts as $post){
$get_post_ids[] = $post->ID;
}
if ( sizeof( $get_post_ids ) > 0 ) {
$search = str_replace( 'AND (((', "AND ((({$wpdb->posts}.ID IN (" . implode( ',', $get_post_ids ) . ")) OR (", $search);
}
return $search;
}
add_filter( 'posts_search', 'search_product_by_tag', 999, 2 );
您的代码中有很多错误和错误(例如,需要税务查询)。
要仅在WooCommerce产品搜索(前端)中包含WooCommerce产品标签术语,请使用以下内容:
add_filter( 'posts_search', 'woocommerce_search_product_tag_extended', 999, 2 );
function woocommerce_search_product_tag_extended( $search, $query ) {
global $wpdb, $wp;
$qvars = $wp->query_vars;
if ( is_admin() || empty($search) || ! ( isset($qvars['s'])
&& isset($qvars['post_type']) && ! empty($qvars['s'])
&& $qvars['post_type'] === 'product' ) ) {
return $search;
}
// Here set your custom taxonomy
$taxonomy = 'product_tag'; // WooCommerce product tag
// Get the product Ids
$ids = get_posts( array(
'posts_per_page' => -1,
'post_type' => 'product',
'post_status' => 'publish',
'fields' => 'ids',
'tax_query' => array( array(
'taxonomy' => $taxonomy,
'field' => 'name',
'terms' => esc_attr($qvars['s']),
)),
));
if ( count( $ids ) > 0 ) {
$search = str_replace( 'AND (((', "AND ((({$wpdb->posts}.ID IN (" . implode( ',', $ids ) . ")) OR (", $search);
}
return $search;
}
代码进入函数。活动子主题(或活动主题)的php文件。测试和工作。
要使其在WordPress搜索上工作,请替换:
if ( is_admin() || empty($search) || ! ( isset($qvars['s'])
&& isset($qvars['post_type']) && ! empty($qvars['s'])
&& $qvars['post_type'] === 'product' ) ) {
通过以下方式:
if ( is_admin() || empty($search) || ! ( isset($qvars['s']) && ! empty($qvars['s']) ) ) {
对于WooCommerce产品类别,您将替换:
$taxonomy = 'product_tag'; // WooCommerce product tag
与:
$taxonomy = 'product_cat'; // WooCommerce product category
对于WooCommerce产品品牌,您将替换:
$taxonomy = 'product_tag'; // WooCommerce product tag
与:
$taxonomy = 'product_brand'; // WooCommerce product Brands
要启用产品类别术语和产品标签术语的搜索,您将使用:
add_filter( 'posts_search', 'woocommerce_search_product_tag_extended', 999, 2 );
function woocommerce_search_product_tag_extended( $search, $query ) {
global $wpdb, $wp;
$qvars = $wp->query_vars;
if ( is_admin() || empty($search) || ! ( isset($qvars['s'])
&& isset($qvars['post_type']) && ! empty($qvars['s'])
&& $qvars['post_type'] === 'product' ) ) {
return $search;
}
// Here set your custom taxonomies in the array
$taxonomies = array('product_tag', 'product_cat');
$tax_query = array('relation' => 'OR'); // Initializing tax query
// Loop through taxonomies to set the tax query
foreach( $taxonomies as $taxonomy ) {
$tax_query[] = array(
'taxonomy' => $taxonomy,
'field' => 'name',
'terms' => esc_attr($qvars['s']),
);
}
// Get the product Ids
$ids = get_posts( array(
'posts_per_page' => -1,
'post_type' => 'product',
'post_status' => 'publish',
'fields' => 'ids',
'tax_query' => $tax_query,
) );
if ( sizeof( $ids ) > 0 ) {
$search = str_replace( 'AND (((', "AND ((({$wpdb->posts}.ID IN (" . implode( ',', $ids ) . ")) OR (", $search);
}
return $search;
}
