Php 在wordpress中使用posts\u的查询中使用多个元键

在这里，我想添加多个元键的查询，如下所示：

$where .= " AND meta_key='order_assign_delivery_date' AND meta_value LIKE '0000%' And meta_key='order_assign_data' AND meta_value=0";

那么现在怎么做呢

上面的查询不起作用，这是显而易见的

请指导我如何在帖子中的同一查询中使用多个meta键，其中filter

首先，您必须使用

自定义帖子\u join

过滤器设置两个postETA

function custom_posts_join($join){
 global $wpdb;
 $join .= " LEFT JOIN $wpdb->postmeta as meta_1 ON $wpdb->posts.ID = meta_1.post_id LEFT JOIN $wpdb->postmeta as meta_2 ON $wpdb->posts.ID = meta_2.post_id";
 return $join;
}
add_filter( 'posts_join' , 'custom_posts_join');

然后你就可以把柱子放在哪里了

function filter_where( $where = '' ) {
       $where .= " AND meta_1.meta_key='order_assign_delivery_date' AND meta_1.meta_value LIKE '0000%' And meta_2.meta_key='order_assign_data' AND meta_2.meta_value=0";
}
add_filter('posts_where', 'filter_where');
