在 WooCommerce 产品搜索中启用自定义分类法

Enable custom taxonomies in WooCommerce product search

我想要的: 修改 WooCommerce 搜索表单(在前端)的查询以通过搜索名称、描述和 product_tag 来显示产品产品。

我有: 我正在尝试使用此代码 inspired from this answer return 产品名称和描述的结果。但是,如果我使用标签名称进行搜索,则没有结果。搜索查询不在产品标签中搜索。

如何重现此问题(将下面的代码放入您的活动主题的 functions.php 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 );

示例: 我有一种产品:带有产品标签“糖果”的黑巧克力。使用此代码,如果我在搜索表单中搜索“巧克力”,该产品将被 returned。但如果我搜索“糖果”:没有结果。

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 产品搜索中包含 WooCommmerce 产品标签条款 (前端) 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;
}

To make it work On WordPress search too replace:

    if ( is_admin() || empty($search) ||  ! ( isset($qvars['s'])
    && isset($qvars['post_type']) && ! empty($qvars['s'])
    && $qvars['post_type'] === 'product' ) ) {

By the following:

    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

对于多个分类法。

要启用对 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;
}
