Question

从wordpress官方文档网站，有一个搜索参数

http://codex.wordpress.org/Class_Reference/WP_Query#Search_Parameter

是&s={keywords}

但是，我想知道这个搜索是基于邮政的一切吗？这意味着如果我提供&s=book，那么如果帖子有一个名字=＆＃34; abc＆＃34;这是＆＃34; book＆＃34;的一个类别，它仍然包含在搜索结果中。有没有办法将搜索特定到title_plain？

感谢您的帮助。

Answer 1

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( like_escape( $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 );

为什么你要使用wp_query只根据标题来搜索帖子..当你在wordpress中为它预先构建的函数时？

<强> Get Page By Title

如何在wordpress WP_Query中按标题搜索？
