我一直在努力从Wordpress中提取父类别帖子。当我试图显示唯一的父类别时,也会发布显示子类别帖子的wordpress查询。
如何省略子类别帖子。请帮忙!! ..
<?
// Get the post ID
$id = get_the_ID();
//get all the categories ( this function will return all categories for a post in an array)
$category= get_the_category( $id );
if ($category->category_parent == 0) {
//extract the first category from the array
$catID = $category[0]->cat_ID;
//Assign the category ID into the query
$verticalNavigationSwitcher = "cat=$catID&orderby=ID&order=ASC";
}
$result = new WP_Query($verticalNavigationSwitcher);
//$featuredPosts->query('showposts=5&cat=3');
while ($result->have_posts()) : $result->the_post();
?>
<li><a href='<?php the_permalink() ?>'><span><?php the_title(); ?></span></a></li>
<?php
endwhile;
wp_reset_postdata();
?>

尝试使用此查询:
$verticalNavigationSwitcher = "category__in=$catID&orderby=ID&order=ASC";
