如何查询仅搜索帖子标题？

Question

我试过了，但我不断收到所有帖子

$post_ids_post = $wpdb->get_col( $wpdb->prepare(
    "SELECT DISTINCT ID FROM {$wpdb->posts} WHERE post_title LIKE '%s'", 
    $search, $search 
));
$tit = array(
    'post__in' => $post_ids_post,
    's' => $s
);

我通过 GET 向搜索结果页面发送一个 var，如果表单检查了 TITLE，则意味着用户只想按标题搜索 $term，但用户可以选择按类别搜索，因此我不能覆盖整个查询。我只需要针对帖子标题的特定查询

//put this code in the functions.php file.
    function title_filter( $where, &$wp_query )
    {
        global $wpdb;
        if ( $search_term = $wp_query->get( 'search_prod_title' ) ) {
            $where .= ' AND ' . $wpdb->posts . '.post_title LIKE \'%' . esc_sql( like_escape( $search_term ) ) . '%\'';
        }
        return $where;
    }
