Woocommerce 管理员搜索多个产品名称

Question

我想同时在 Woocommerce 中搜索多个产品。因此，我不想逐一搜索，而是输入以逗号或类似内容分隔的产品列表。

我发现 Bjorn 的这段代码可以同时搜索多个 SKU，但我想按产品名称进行搜索。这可能吗？

/**
 * Use multiple sku's to find WOO products in wp-admin
 * NOTE: Use '|' as a sku delimiter in your search query. Example: '1234|1235|1236'
**/
function woo_multiple_sku_search( $query_vars ) {

    global $typenow;
    global $wpdb;
    global $pagenow;

    if ( 'product' === $typenow && isset( $_GET['s'] ) && 'edit.php' === $pagenow ) {
        $search_term = esc_sql( sanitize_text_field( $_GET['s'] ) );

        if (strpos($search_term, '|') == false) return $query_vars;

        $skus = explode('|',$search_term);

        $meta_query = array(
            'relation' => 'OR'
        );
        if(is_array($skus) && $skus) {
            foreach($skus as $sku) {
                $meta_query[] = array(
                    'key' => '_sku',
                    'value' => $sku,
                    'compare' => '='
                );
            }
        }

        $args = array(
            'posts_per_page'  => -1,
            'post_type'       => 'product',
            'meta_query'      => $meta_query
        );
        $posts = get_posts( $args );

        if ( ! $posts ) return $query_vars;

        foreach($posts as $post){
          $query_vars['post__in'][] = $post->ID;
        }
    }

    return $query_vars;
}
add_filter( 'request', 'woo_multiple_sku_search', 20 );

要按产品名称而不是产品 SKU 进行搜索，您可以使用自定义 SQL 查询并搜索

post_title

（WooCommerce 产品是自定义帖子类型）。

此外，您不必单独声明多个全局变量，您可以通过用“逗号”分隔将它们全部写入一个实例中。 （这并没有什么最大的区别）。

要按

,

（逗号）而不是

|

或任何您想要的符号/分隔符进行搜索，您只需更改这两行代码中的指示符（例如

'|'

或

','

或

'+' 

）：

if (strpos($search_term, ',') === false) return $query_vars;

$terms = explode(',', $search_term);

将现有代码替换为以下代码：

/*Search multiple product names in WOO products in wp-admin*/
function woo_multiple_name_search( $query_vars ) {
    global $typenow, $pagenow, $wpdb; // Declaring global variables

    // Check if we are in the admin area, on the product edit page, and a search is being performed
    if ( is_admin() && 'product' === $typenow && isset( $_GET['s'] ) && 'edit.php' === $pagenow ) {
        $search_term = esc_sql( sanitize_text_field( $_GET['s'] ) );

        // Check if the search term contains ',' indicating multiple search terms
        if (strpos($search_term, ',') === false) return $query_vars;

        $terms = explode(',', $search_term); // Split the search terms by ',' comma
        $post_ids = array(); // Initialize an array to hold the post IDs

        // Loop through each element in $terms array
        foreach ($terms as $term) {
            // Custom SQL query to search by product name
            $name_query = $wpdb->get_results($wpdb->prepare("
                SELECT ID FROM {$wpdb->posts}
                WHERE post_type = 'product'
                AND post_title LIKE %s
            ", '%' . $wpdb->esc_like($term) . '%'));

            // If there are results, add the post IDs to the array
            if ($name_query) {
                foreach ($name_query as $post) {
                    $post_ids[] = $post->ID;
                }
            }
        }

        // If no posts are found, return the original query vars
        if ( ! $post_ids ) return $query_vars;

        // Set the post__in parameter to the array of post IDs
        $query_vars['post__in'] = $post_ids;
    }

    return $query_vars;
}
add_filter( 'request', 'woo_multiple_name_search', 20 );
