Question

我试图在内部使用相同的ACF获取所有帖子。例如。理想情况下，我需要一个存档页面或自定义类别页面，其中包含包含给定字段的帖子。

尝试按照此处显示的步骤进行操作：http://www.advancedcustomfields.com/resources/acf-fields-post_object-query/

并在functions.php中创建过滤器，如下所述：

function my_post_object_query( $args, $field, $post )
{
    // modify the order
    $args['orderby'] = 'title';

    return $args;
}

// filter for every field
add_filter('acf/fields/post_object/query', 'my_post_object_query', 10, 3);

// filter for a specific field based on it's name
add_filter('acf/fields/post_object/query/name=my_select', 'my_post_object_query', 10, 3);

// filter for a specific field based on it's key
add_filter('acf/fields/post_object/query/key=field_508a263b40457', 'my_post_object_query', 10, 3);

但是不太明白如何在某个给定页面上发帖...例如localhost/?<customfieldname>=<customfield_value>

您最好的办法是为其创建页面或存档模板，并将其与以下查询结合使用：

<?php 
$posts = get_posts(array(
    'numberposts'   => -1,
    'post_type'     => 'post',   // could also be page or your custom post_type
    'meta_key'      => 'color',  // your ACF field name
    'meta_value'    => 'red'     // Your ACF field value
));
?>
