WP_Query什么都不返回

Question

我试图创造一个功能 它添加了一个短代码，用于将短代码替换为带有分页的附加文件列表。

问题是，WP_Query（）并没有返回任何内容。

功能代码如下。 它在我的functions.php中，它将在我的content-page.php中调用。

$a = shortcode_atts( array( 'number' => '10'), $atts );

//Protect against arbitrary paged values
$paged = ( get_query_var( 'paged' ) ) ? absint( get_query_var( 'paged' ) ) : 1;

$args = array(
    'post_type' => 'attachment',
    'post_parent' => get_the_ID(),
    'posts_per_page' => $a['number'],
    'paged' => $paged
);

$the_query = new WP_Query( $args );

if ( $the_query->have_posts() ) :

    while ( $the_query->have_posts() ) : $the_query->the_post();
        the_title();
    endwhile;

    $big = 999999999; // need an unlikely integer

    $retuen_string .= paginate_links( array(
        'base' => str_replace( $big, '%#%', esc_url( get_pagenum_link( $big ) ) ),
        'format' => '?paged=%#%',
        'current' => max( 1, get_query_var('paged') ),
        'total' => $the_query->max_num_pages
    ) );

    wp_reset_postdata();

else :
    _e( 'Sorry, no posts matched your criteria.' );
endif;

并且print_r（$ the_query）结果如下。

有人可以帮忙吗？

我找到了解决方案。 不得不添加'post_status'=＆gt; '继承'在$ args中。 像这样。

$args = array(
    'post_type' => 'attachment',
    'post_parent' => get_the_ID(),
    'posts_per_page'=>'15',
    'paged' => $paged,
    'post_status' => 'inherit'
);

OMG。很简单。 代码没有错。 我刚刚通过了错误的论点......
