我想在搜索表单中输入位置后按最近的位置订购产品。我使用ACF中的Google地图为产品分配位置，该字段称为“地址”。我还有Google为我的表单和ACF谷歌地图半径搜索插件添加了自动填充功能。我的表单重定向到包含lat和lng变量的URL：
/?s=&post_type=product&lat=43.26768079999999&lng=6.640710899999931
该插件应该从此网址订购产品。 lat和lng在URL中传递得很好。不幸的是，它不会改变搜索产品的顺序。
以下是该插件的一些关键功能：
// Join for searching metadata
function acf_google_maps_search_join_to_WPQuery($join) {
global $wpdb;
$acf_gms = new acf_gms;
$table_name = $acf_gms->table_name();
if (
isset($_GET['lat']) && !empty($_GET['lat'])
&& isset( $_GET['lng']) && !empty($_GET['lng'])
) {
$join .= " LEFT JOIN {$table_name} AS acf_gms_geo ON {$wpdb->posts}.ID = acf_gms_geo.post_id ";
}
return $join;
}
add_filter('posts_join', 'acf_google_maps_search_join_to_WPQuery');
// ORDER BY DISTANCE
function acf_google_maps_search_orderby_WPQuery($orderby) {
if (
isset($_GET['lat']) && !empty($_GET['lat'])
&& isset( $_GET['lng']) && !empty($_GET['lng'])
) {
$lat = sanitize_text_field( $_GET['lat'] );
$lng = sanitize_text_field( $_GET['lng'] );
$orderby = " (POW((acf_gms_geo.lng-{$lng}),2) + POW((acf_gms_geo.lat-{$lat}),2)) ASC";
}
return $orderby;
}
add_filter('posts_orderby', 'acf_google_maps_search_orderby_WPQuery');
这是传递给结果页面的SQL查询：
SELECT wp_posts.*
FROM wp_posts
INNER JOIN wp_postmeta
ON ( wp_posts.ID = wp_postmeta.post_id )
INNER JOIN wp_postmeta AS mt1
ON ( wp_posts.ID = mt1.post_id )
INNER JOIN wp_postmeta AS mt2
ON ( wp_posts.ID = mt2.post_id )
LEFT JOIN wp_acf_google_map_search_geodata AS acf_gms_geo
ON wp_posts.ID = acf_gms_geo.post_id
WHERE 1=1
AND (
( wp_postmeta.meta_key = ‘flash_sale_start’
AND CAST(wp_postmeta.meta_value AS DATE) > ‘20180122’
)
AND ( mt1.meta_key = ‘flash_sale_end’
AND CAST(mt1.meta_value AS DATE) > ‘20180122’
)
AND ( mt2.meta_key = ‘flash_sale_start’
AND CAST(mt2.meta_value AS DATE) <= ‘20180127’
)
)
AND wp_posts.post_type = ‘product’
AND ((wp_posts.post_status = ‘publish’))
GROUP BY wp_posts.ID
ORDER BY (POW((acf_gms_geo.lng-6.640710899999931),2) + POW((acf_gms_geo.lat-43.26768079999999),2)) ASC
你对这个问题有所了解吗？
谢谢

我发现了问题。我在functions.php中有两个meta_query，根据两个不同的规则在我的页面的两个不同位置显示产品。
插件触发的ORDER BY位置仅出现在其中一个sql查询中，但不出现在此查询中（尽管出现LEFT JOIN部分）：
SELECT SQL_CALC_FOUND_ROWS wp_posts.ID FROM wp_posts
INNER JOIN wp_postmeta ON ( wp_posts.ID = wp_postmeta.post_id )
INNER JOIN wp_postmeta AS mt1 ON ( wp_posts.ID = mt1.post_id )
INNER JOIN wp_postmeta AS mt2 ON ( wp_posts.ID = mt2.post_id )
//下面你可以看到插件的左侧连接部分出现
LEFT JOIN wp_acf_google_map_search_geodata AS acf_gms_geo ON wp_posts.ID = acf_gms_geo.post_id WHERE 1=1 AND wp_posts.ID NOT IN (968) AND (
wp_posts.ID NOT IN (
SELECT object_id
FROM wp_term_relationships
WHERE term_taxonomy_id IN (10)
)
) AND (
wp_postmeta.meta_key = ‘total_sales’
AND
(
(
( mt1.meta_key = ‘flash_sale_start’ AND CAST(mt1.meta_value AS DATE) <= ‘20180125’ )
AND
( mt2.meta_key = ‘flash_sale_end’ AND CAST(mt2.meta_value AS DATE) >= ‘20180125’ )
)
)
) AND wp_posts.post_type = ‘product’ AND (wp_posts.post_status = ‘publish’ OR wp_posts.post_status = ‘complete’ OR wp_posts.post_status = ‘paid’ OR wp_posts.post_status = ‘confirmed’ OR wp_posts.post_status = ‘unpaid’ OR wp_posts.post_status = ‘pending-confirmation’ OR wp_posts.post_status = ‘cancelled’ OR wp_posts.post_status = ‘private’)
GROUP BY wp_posts.ID
//但是插件的部分顺序下方没有出现
ORDER BY wp_postmeta.meta_value+0 DESC, wp_posts.post_date DESC LIMIT 0, 100
你知道怎么纠正这个吗？

我有这个meta_query：
$today = current_time('Ymd');
$args = array (
'numberposts' => -1,
'post_status' => 'publish',
'post_type' => 'product',
'meta_query' => array(
'relation' => 'AND',
'start_clause' => array(
'key'=>'flash_sale_start',
'value' => $today,
'compare'=> '<=',
'type' => 'DATE'
),
'end_clause' => array(
'key' => 'flash_sale_end',
'value' => $today,
'compare' => '>=',
'type' => 'DATE'
)
)
);
return $args;
}
// The main shop and archives meta query
add_filter( 'woocommerce_product_query_meta_query', 'custom_product_query_meta_query', 10, 2 );
function custom_product_query_meta_query( $meta_query, $query ) {
if( ! is_admin() )
return custom_meta_query( $meta_query );
}
取决于以下sql查询，它不显示orderby位置：
SELECT SQL_CALC_FOUND_ROWS wp_posts.ID FROM wp_posts
INNER JOIN wp_postmeta ON ( wp_posts.ID = wp_postmeta.post_id )
INNER JOIN wp_postmeta AS mt1 ON ( wp_posts.ID = mt1.post_id )
INNER JOIN wp_postmeta AS mt2 ON ( wp_posts.ID = mt2.post_id )
LEFT JOIN wp_acf_google_map_search_geodata AS acf_gms_geo ON wp_posts.ID = acf_gms_geo.post_id WHERE 1=1 AND wp_posts.ID NOT IN (968) AND (
wp_posts.ID NOT IN (
SELECT object_id
FROM wp_term_relationships
WHERE term_taxonomy_id IN (10)
)
) AND (
wp_postmeta.meta_key = ‘total_sales’
AND
(
(
( mt1.meta_key = ‘flash_sale_start’ AND CAST(mt1.meta_value AS DATE) <= ‘20180125’ )
AND
( mt2.meta_key = ‘flash_sale_end’ AND CAST(mt2.meta_value AS DATE) >= ‘20180125’ )
)
)
) AND wp_posts.post_type = ‘product’ AND (wp_posts.post_status = ‘publish’ OR wp_posts.post_status = ‘complete’ OR wp_posts.post_status = ‘paid’ OR wp_posts.post_status = ‘confirmed’ OR wp_posts.post_status = ‘unpaid’ OR wp_posts.post_status = ‘pending-confirmation’ OR wp_posts.post_status = ‘cancelled’ OR wp_posts.post_status = ‘private’)
GROUP BY wp_posts.ID
ORDER BY wp_postmeta.meta_value+0 DESC, wp_posts.post_date DESC LIMIT 0, 100
我也有这个元查询：
$products = new WP_Query( array (
'post_type' => 'product',
'post_status' => 'publish',
'posts_per_page' => $atts['limit'],
'meta_query' => array(
'relation' => 'AND',
'start_clause' => array(
'key' =>'flash_sale_start',
'value' => $today,
'compare' => '>',
'type' => 'DATE'
),
'end_clause' => array(
'key' => 'flash_sale_end',
'value' => $today,
'compare' => '>',
'type' => 'DATE'
),
'limit_clause' => array(
'key' => 'flash_sale_start',
'value' => $limitdate,
'compare' => '<=',
'type' => 'DATE'
)
)
));
}
ob_start();
if ( $products->have_posts() ) { ?>
<?php woocommerce_product_loop_start(); ?>
<?php while ( $products->have_posts() ) : $products->the_post(); ?>
<?php wc_get_template_part( 'content', 'product' ); ?>
<?php endwhile; // end of the loop. ?>
<?php woocommerce_product_loop_end(); ?>
<?php
} else {
do_action( "woocommerce_shortcode_products_loop_no_results", $atts );
echo "<p>Aucune vente à venir pour le moment.</p>";
}
woocommerce_reset_loop();
wp_reset_postdata();
return '<div class="woocommerce columns-' . $atts['columns'] . '">' . ob_get_clean() . '</div>';
}
add_shortcode( 'upcoming_sales', 'upcoming_sales' );
从中依赖于这个sql_query，它显示插件所包含的orderby位置：
SELECT wp_posts.*
FROM wp_posts
INNER JOIN wp_postmeta
ON ( wp_posts.ID = wp_postmeta.post_id )
INNER JOIN wp_postmeta AS mt1
ON ( wp_posts.ID = mt1.post_id )
INNER JOIN wp_postmeta AS mt2
ON ( wp_posts.ID = mt2.post_id )
LEFT JOIN wp_acf_google_map_search_geodata AS acf_gms_geo
ON wp_posts.ID = acf_gms_geo.post_id
WHERE 1=1
AND (
( wp_postmeta.meta_key = ‘flash_sale_start’
AND CAST(wp_postmeta.meta_value AS DATE) > ‘20180122’
)
AND ( mt1.meta_key = ‘flash_sale_end’
AND CAST(mt1.meta_value AS DATE) > ‘20180122’
)
AND ( mt2.meta_key = ‘flash_sale_start’
AND CAST(mt2.meta_value AS DATE) <= ‘20180127’
)
)
AND wp_posts.post_type = ‘product’
AND ((wp_posts.post_status = ‘publish’))
GROUP BY wp_posts.ID
ORDER BY (POW((acf_gms_geo.lng-6.640710899999931),2) + POW((acf_gms_geo.lat-43.26768079999999),2)) ASC
你知道为什么插件不能在第一个sql查询中执行orderby吗？
答案 2 :(得分：0)
我设法让它发挥作用!!由于woocommerce有自己订购产品的东西，所以只需写一个这样的函数：
if(isset($_GET['lat']) and $_GET['lat'] != "" and isset($_GET['lng']) and $_GET['lng'] != "")
{
add_filter( 'woocommerce_default_catalog_orderby', 'custom_woocommerce_get_catalog_ordering_args'
);
}
function custom_woocommerce_get_catalog_ordering_args( $args ) {
$lat = sanitize_text_field( $_GET['lat'] );
$lng = sanitize_text_field( $_GET['lng'] );
$args['orderby'] = ' (POW((acf_gms_geo.lng-{$lng}),2) + POW((acf_gms_geo.lat-
{$lat}),2))';
$args['order'] = 'ASC';
$args['meta_key'] = '';
return $args;
}
