如何查询以获取正确的计数（acf 字段/wordpress）？

Question

当前帖子的 firstsubmission 字段（acf 字段）为空。
因此，查询应该显示 0，但它显示 1。
我尝试了以下代码，所有代码都显示为 1。
你能告诉我如何得到正确的计数0吗？

    $posts = array(
    'author'            => get_current_user_id(),
    'posts_per_page'    => -1,
    'post_title'        => get_the_title(),
    'post_type'         => 'infosubmission',
    'meta_query'        => array(
            array(
            'key'       => 'firstsubmission',
            'value'     => 'done'
        )
     )
  );

$post_b = new WP_Query( $posts );
$the_count = count($post_b); 
echo 'COUNT:' .$the_count;

$posts = get_posts(array(
    'author'            => get_current_user_id(),
    'posts_per_page'    => -1,
    'post_title'        => get_the_title(),
    'post_type'         => 'infosubmission',
    'meta_key'          => 'firstsubmission',
    'meta_value'        => 'done'
));

$the_query = new WP_Query( $posts );
$the_count = count($the_query); 
echo 'COUNT:' .$the_count;

$infopost = [
    'author'         => get_current_user_id(),
    'post_type'      => 'infosubmission',
    'posts_per_page' => -1, 
    'post_title'     => get_the_title(),
    'firstsubmission' => 'done'
];

$info_posts = new WP_Query($infopost);
$info_count = count($info_posts);   
echo 'COUNT:' .$info_count;

谢谢你。

/* please replace below snippet in your code */

$posts = get_posts(array(
    'author'            => get_current_user_id(),
    'posts_per_page'    => -1,
    'post_title'        => get_the_title(),
    'post_type'         => 'infosubmission',
    'meta_key'          => 'firstsubmission',
    'meta_value'        => 'done',
    'meta_compare'   => '=' 

));
