Question

我试图在wordpress中制作OR条件。但它没有对WP_Query（$ args）的查询产生任何影响我对wordpress很新，所以我对wordpress查询的流程一无所知。

 if ( $params ) {
            extract($params);
            $args['meta_query'] = array(
                'relation' => 'OR'
            );
            if (isset( $keywords )) {
                $args['meta_query'][] = array(
                'meta_key' => 'eltd_listing_address',
                'meta_value' => $keywords,
                );
            }
            if (isset($type)) {
                if($type !== '' && $type !=='all' ){
                    $args['meta_query'][] = array(
                    'meta_key' => 'eltd_listing_item_type',
                    'meta_value' => $type,
                    );
                }
            }
            if (isset($number)) {
                $args['posts_per_page'] = $number;
            }


            $args['tax_query'] = array(
                'relation' => 'AND'
            );

            if ( isset( $category ) ) {
                if($category !== '' && $category !=='all' ){
                    $args['tax_query'][] = array(
                        'taxonomy' => 'listing-item-category',
                        'field' => 'term_id',
                        'terms' => (int)$category
                    );
                }
            }

            if ( isset($location) ) {
                if($location !== '' && $location !=='all' ){
                    $args['tax_query'][] = array(
                        'taxonomy' => 'listing-item-location',
                        'field' => 'term_id',
                        'terms' => (int)$location
                    );
                }
            }

            if ( isset($tag) ) {
                $args['tax_query'][] = array(
                    'taxonomy' => 'listing-item-tag',
                    'field' => 'term_id',
                    'terms' => (int)$tag
                );
            }

        }

        $query = new WP_Query($args);

当我在$ query-＆gt;中显示请求时，它似乎就是这样。

在$ args中我得到了

 Array
(
    [post_type] => listing-item
    [post_status] => publish
    [meta_query] => Array
        (
            [relation] => OR
            [0] => Array
                (
                    [meta_key] => eltd_listing_address
                    [meta_value] => Carrer de la Princesa, 24-26, 08003 Barcelona, Spain
                )

            [1] => Array
                (
                    [meta_key] => eltd_listing_item_type
                    [meta_value] => 277
                )

        )

    [posts_per_page] => 12
)




 SELECT SQL_CALC_FOUND_ROWS  wp_posts.ID FROM wp_posts  WHERE 1=1  AND wp_posts.post_type = 'listing-item' AND ((wp_posts.post_status = 'publish')) GROUP BY wp_posts.ID ORDER BY wp_posts.post_date DESC LIMIT 0, 12

这里我没有得到OR条件。

我不知道如何在wordpress中做。任何解决方案将高度赞赏。

您需要为每个键设置元查询的比较参数...所以

        if (isset( $keywords )) {
            $args['meta_query'][] = array(
            'meta_key' => 'eltd_listing_address',
            'meta_value' => $keywords,
            );
        }
        if (isset($type)) {
            if($type !== '' && $type !=='all' ){
                $args['meta_query'][] = array(
                'meta_key' => 'eltd_listing_item_type',
                'meta_value' => $type,
                );
            }
        }

变为

        if (isset( $keywords )) {
            $args['meta_query'][] = array(
            'meta_key' => 'eltd_listing_address',
            'meta_value' => $keywords,
            'compare' => '=',
            );
        }
        if (isset($type)) {
            if($type !== '' && $type !=='all' ){
                $args['meta_query'][] = array(
                'meta_key' => 'eltd_listing_item_type',
                'meta_value' => $type,
                'compare' => '=',
                );
            }
        }

wordpress中的OR条件不起作用
