如何显示特定类别的附件？

我尝试添加

'category_name' => 'my-category-slug'

但它无效

 <?php $attachments = get_children(array(
            'post_parent' => null,
            'post_type' => 'attachment',
            'post_mime_type' => 'image',
            'posts_per_page' => 35,
            'post_status' => 'any',
            'exclude'  => get_post_thumbnail_id(),
            'orderby' => 'rand'
                    )); 
foreach($attachments as $att_id => $attachment) {
$full_img_url = wp_get_attachment_url($attachment->ID);

 echo '<li>';
 echo '<a href="' . wp_get_attachment_url($attachment->ID) . '"data-lightbox="galerija-front">';
 echo wp_get_attachment_image($attachment->ID, 'galerija-front', false, $attr);
 echo '</a>';
 echo '</li>'; }
?>

您可以使用get_posts代替get_children。此外，您是否尝试过使用tax_query并指定类别的分类和术语？

示例：

$attachments = get_posts(array(
    'post_type' => 'attachment',
    'post_mime_type' => 'image',
    'posts_per_page' => 35,
    'post_status' => 'any',
    'post__not_in'  => array(get_post_thumbnail_id()),
    'orderby' => 'rand',
    'tax_query' => array(
        array(
            'taxonomy' => 'category_name',
            'field' => 'slug',
            'terms' => 'my-category-slug'
        )
    )
));

'category_name'和'my-category-slug'分别是分类和slu ..
