我使用以下代码使wordpress仅按产品标题进行搜索。但是,woocommerce的"按属性过滤"小部件仍然显示过滤器,就好像搜索也是在正文文本上完成的一样。
因此,例如,如果我搜索"脸",显示的结果标题中都有"脸",但"按属性过滤"小部件仍将巧克力显示为属性,因为有一个巧克力棒的描述"面对现实,我们都喜欢巧克力"
然后,如果您单击"巧克力"过滤器,它将不显示任何结果,因为搜索仅显示标题中带有"脸"的结果。
我什至不知道从哪里开始寻求更改按属性过滤器小部件的行为。
// Search titles only
function __search_by_title_only( $search, $wp_query )
{
global $wpdb;
if(empty($search)) {
return $search; // skip processing - no search term in query
}
$q = $wp_query->query_vars;
$n = !empty($q['exact']) ? '' : '%';
$search =
$searchand = '';
foreach ((array)$q['search_terms'] as $term) {
$term = esc_sql($wpdb->esc_like($term));
$search .= "{$searchand}($wpdb->posts.post_title LIKE '{$n}{$term}{$n}')";
$searchand = ' AND ';
}
if (!empty($search)) {
$search = " AND ({$search}) ";
if (!is_user_logged_in())
$search .= " AND ($wpdb->posts.post_password = '') ";
}
return $search;
}
add_filter('posts_search', '__search_by_title_only', 500, 2);
我已经拼凑了我自己的过滤器,它与上述搜索(仅标题)配合得很好,并且不显示任何标题中没有关键字的项目的品牌。我现在唯一的问题是弄清楚如何获取项目计数。
