如何显示特定类别的附件？
我试着添加
'category_name' => 'my-category-slug'
但它不起作用
<?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而不是get_children。此外，您是否尝试过使用tax_query并指定类别的分类法和术语？
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'
)
)
));
其中"category_name"answers"my category-slug"分别是分类法和slug。
