如何将所需的“meta_query”参数从 WP_Query 传递给 $_POST？

  • 772

请帮我弄清楚。我使用这个插件来实现点击加载帖子的按钮：https ://wordpress.org/plugins/infinite-scroll-and-ajax-load-more/

只要使用 wordpress 在 archive.php 中提供的标准方法来显示帖子，它的工作就没有问题：

if ( have_posts() ) : 
        while ( have_posts() ) :
            the_post();

但在新部分中，有必要分别使用 meta_query 和 WP_Query 参数，通过 AFC 日期字段将帖子分为过去和即将发布的帖子：

$compare = ( $_GET['type'] === 'past' ) ? '<' : '>=';
$today   = date( 'Ymd' );
$args = array(
    'post_type'      => 'training',
    'meta_query'     => array(
        array(
            'key'     => 'event_time_event_day',
            'value'   => $today,
            'compare' => $compare,
            'type'    => 'DATE'
        )
    ),
    'meta_key'       => 'event_time_event_day',
    'orderby'        => 'meta_value',
    'order'          => 'DESC',
    'posts_per_page' => '5',
);

$wp_query = new WP_Query( $args );

当您单击“显示更多”按钮时，该插件会传递循环参数：

wp_localize_script( 'bliss_loadmore', 'bliss_loadmore_params', array(
            'ajaxurl'        => site_url() . '/wp-admin/admin-ajax.php',
            'posts'          => json_encode( $wp_query->query_vars )
            ...................

        ) );

但是 query_vars 包含，如我所见（我并没有真正在 wp 中翻找），在帖子的标准输出中使用的参数，我在开头写过：（对不起，在一行中）

 [query] => {"post_type":"training","error":"","m":"","p":0,"post_parent":"","subpost":"","subpost_id":"","attachment":"","attachment_id":0,"name":"","pagename":"","page_id":0,"second":"","minute":"","hour":"","day":0,"monthnum":0,"year":0,"w":0,"category_name":"","tag":"","cat":"","tag_id":"","author":"","author_name":"","feed":"","tb":"","paged":0,"meta_key":"","meta_value":"","preview":"","s":"","sentence":"","title":"","fields":"","menu_order":"","embed":"","category__in":[],"category__not_in":[],"category__and":[],"post__in":[],"post__not_in":[],"post_name__in":[],"tag__in":[],"tag__not_in":[],"tag__and":[],"tag_slug__in":[],"tag_slug__and":[],"post_parent__in":[],"post_parent__not_in":[],"author__in":[],"author__not_in":[],"posts_per_page":5,"ignore_sticky_posts":false,"suppress_filters":false,"cache_results":true,"update_post_term_cache":true,"lazy_load_term_meta":true,"update_post_meta_cache":true,"nopaging":false,"comments_per_page":"50","no_found_rows":false,"order":"DESC"}

如您所见，这里没有“meta_query”参数。如果您输出$wp_query，您会发现以下内容：

"tax_query":{"meta_query":{"queries":[],"relation":null,"meta_table":null,"meta_id_column":null,"primary_table":null,"primary_id_column":null}...

因此，当您单击“显示更多”时，过去和即将发生的事件都会显示在两个部分中（对于两个获取请求）。你能告诉我如何传递所需的参数吗？

    所以问题通过添加解决了

    wp_add_inline_script('bliss_loadmore', "
    bliss_loadmore_params.posts = '".json_encode($args)."';
", 'before');

    声明后 $wp_query = new WP_Query( $args );
