中的自定义wp搜索查询
$args = array(
        'post_type' => 'post',
        'taxonomy'  => 'location',
        'field' => 'name',
        'posts_per_page' => 10,
        'term' => $keyword,
    );
$wp_query = new WP_Query($args);

我有2个帖子,其位置是伦敦和牛津,伦敦。现在我搜索伦敦然后它只显示1个帖子**(第1个)**。当我搜索牛津时,它显示没有找到结果。

当我搜索牛津伦敦时,它的工作正常。

Befor WP_Query Run编写此代码

function advance_search_where($where){
    global $wpdb;
    if (is_search())
        $where .= "OR (t.name LIKE '%".get_search_query()."%' AND {$wpdb->posts}.post_status = 'publish')";
    return $where;
}

function advance_search_join($join){
    global $wpdb;
    if (is_search())
        $join .= "LEFT JOIN {$wpdb->term_relationships} tr ON {$wpdb->posts}.ID = tr.object_id INNER JOIN {$wpdb->term_taxonomy} tt ON tt.term_taxonomy_id=tr.term_taxonomy_id INNER JOIN {$wpdb->terms} t ON t.term_id = tt.term_id";
    return $join;
}

function advance_search_groupby($groupby){
    global $wpdb;

    // we need to group on post ID
    $groupby_id = "{$wpdb->posts}.ID";
    if(!is_search() || strpos($groupby, $groupby_id) !== false) return $groupby;

    // groupby was empty, use ours
    if(!strlen(trim($groupby))) return $groupby_id;

    // wasn't empty, append ours
    return $groupby.", ".$groupby_id;
}

add_filter('posts_where','advance_search_where');
add_filter('posts_join', 'advance_search_join');
add_filter('posts_groupby', 'advance_search_groupby');

现在运行你的WP_Query像这样

$args = array(
        'post_type' => 'post',
        'posts_per_page' => 10,
        's' => $keyword,
    );
$wp_query = new WP_Query($args);

在您完成所有结果之后,如果您不删除它,则必须删除上面的过滤器,然后它将应用于该页面的其他wp_query。

remove_filter('posts_where','advance_search_where');
remove_filter('posts_join', 'advance_search_join');
remove_filter('posts_groupby', 'advance_search_groupby');
