如何将两个元值传递给 WP_Query

Question

我的 WP_Query 有问题。所以我有两个使用 ACF 创建的 select 框，一个用于国家，一个用于行业。当我 select 国家并将部门留空时，我会获得 selected 国家的所有帖子，并且对于该部门来说也是明智的。我需要做的是进一步过滤它，所以如果两者都被 selected 而不是只有一个，我会得到来自那个国家和部门的所有帖子。我的 args 下面的任何帮助表示赞赏。

$field_key_country = "field_57b4439b5e371";
$field_country = get_field_object($field_key_country);
$country_sector = isset($_POST['country_select'])? sanitize_text_field($_POST['country_select']) : false;

$sector_key = "field_57e15152d896d";
$sector_field = get_field_object($sector_key);
$sector = isset($_POST['sector_select'])? sanitize_text_field($_POST['sector_select']) : false;

$args = array(
   'post_type' => 'distributer_search', 
   'posts_per_page' => -1,
   'meta_query' => array(
       'relation'       => 'OR',
        array(
           'key'        => 'dis_country',
           'value'      => $country_sector,
        ),
        array(
            'key'       => 'dis_sector',
            'value'     => $sector,
        )
    )
);

请尝试使用以下带有关系 AND & 比较运算符的代码。另外请检查 WP_Query class 在 https://codex.wordpress.org/Class_Reference/WP_Query

<?php
 $country_sector = isset($_POST['country_select'])? sanitize_text_field($_POST['country_select']) : '';
 $sector = isset($_POST['sector_select'])? sanitize_text_field($_POST['sector_select']) : '';
 $args = array(
  'post_type' => 'distributer_search', 
  'posts_per_page' => -1,
  'meta_query' => array(
   'relation'       => 'AND',
   array(
    'key'        => 'dis_country',
    'value'      => $country_sector,
    'compare'   => '=',
   ),
   array(
    'key'       => 'dis_sector',
    'value'     => $sector,
    'compare'   => '=',
   )
  )
 );
?>

'distributer_search', 'posts_per_page' => -1, 'meta_query' => 数组( 'relation' => 'AND', 大批（ 'key' => 'dis_country', 'value' => $country_sector, 'compare' => '=', ), 大批（ 'key' => 'dis_sector', 'value' => $扇区, 'compare' => '=', ) ) ); ？>

可能对你有帮助 -

$field_key_country = "field_57b4439b5e371";
$field_country = get_field_object($field_key_country);
$country_sector = isset($_POST['country_select'])? sanitize_text_field($_POST['country_select']) : false;

$sector_key = "field_57e15152d896d";
$sector_field = get_field_object($sector_key);
$sector = isset($_POST['sector_select'])? sanitize_text_field($_POST['sector_select']) : false;

$args = array(
   'post_type' => 'distributer_search', 
   'posts_per_page' => -1
);
if($country_sector){
    $args['meta_query'][] = array(
        'key'        => 'dis_country',
        'value'      => $country_sector
    );
}
if($sector){
    $args['meta_query'][] = array(
        'key'       => 'dis_sector',
        'value'     => $sector
    );
}
