Question

我正在尝试通过postmeta total_sales

订购

function ta_modify_main_query($query) {
   if ($query->is_search()) {
       $query->set('orderby', 'meta_value_num');
       $query->set('meta_key', 'total_sales');
       $query->set('order', 'DESC');
   }
}

add_action( 'pre_get_posts', 'ta_modify_main_query', 999 );

我认为代码很好，但它不起作用，查询时不会更改查询。我的网址看起来像?s=abstract+pattern&post_type=product，使用的查询是

SELECT SQL_CALC_FOUND_ROWS wp_posts.*, ID, (MATCH(post_title) AGAINST ('abstract pattern' ) * 1 ) + (MATCH(post_content) AGAINST ('abstract pattern' ) * 10 ) AS score 
FROM wp_posts 
INNER JOIN wp_postmeta
ON ( wp_posts.ID = wp_postmeta.post_id )
WHERE 1=1 
AND MATCH (post_title,post_content) AGAINST ('abstract pattern' ) 
AND (post_status = 'publish'
OR post_status = 'inherit')
AND wp_posts.post_type IN ('product') 
GROUP BY wp_posts.ID
ORDER BY score DESC 
LIMIT 0, 12

问题是我安装了一个处理搜索的插件，称为更好搜索。

function query_1($query){
    $query .= ",wp_postmeta.meta_value as total_saless ";
    return $query;
}
add_filter( 'bsearch_posts_match_field', 'query_1' );

function query_2($query){
    $query .= "AND wp_postmeta.meta_key='total_sales' ";
    return $query;
}
add_filter( 'bsearch_posts_where', 'query_2' );

function query_3($query){
    $query = " CAST(total_saless AS INTEGER) > 99999 DESC, score DESC ";
    return $query;
}
add_filter( 'bsearch_posts_orderby', 'query_3' );

我所要做的只是勾住它。
