[英]Get categories for a single post in a custom post type
I'm trying to get an unformatted list (preferably a list of slugs) of the categories for a single post in a custom post type loop. 我试图在自定义帖子类型循环中获取单个帖子的类别的无格式列表(最好是子列表)。 This list will eventually serve as a class for a div (
$CATEGORYSLUGSWILLEVENTUALLYGOHERE
). 此列表最终将作为div(
$CATEGORYSLUGSWILLEVENTUALLYGOHERE
)的类。
I've found a few different methods of getting a list of ALL of the categories for a custom post type, but not the ones specific to a single one. 我发现了几种不同的方法来获取自定义帖子类型的所有类别的列表,但没有特定于单个类别的列表。 Here's what I have so far:
这是我到目前为止的内容:
<?php $projects_loop = new WP_Query( array( 'post_type' => 'projects', 'orderby' => 'menu_order' ) ); ?>
<?php while ( $projects_loop->have_posts() ) : $projects_loop->the_post(); ?>
<div class="box <?php $CATEGORYSLUGSWILLEVENTUALLYGOHERE; ?>">
<div class="port-item-home">
<a href="<?php the_permalink(); ?>"><?php the_post_thumbnail( 'portfolio-home' ); ?></a>
<p><a href="<?php the_permalink(); ?>"><?php the_title(); ?></a></p>
</div>
</div>
<?php endwhile; ?>
And here's what I've tried so far to get the category list: 到目前为止,这是我尝试获取类别列表的方法:
<?php
$args = array(
'orderby' => 'name',
'parent' => 0,
'taxonomy' => 'project-type'
);
$categories = get_categories( $args );
echo '<p> '.print_r(array_values($categories)).'something</p>'
?>
I have it returning the array - but the array is showing that it'll display all categories instead of the ones pertaining to that specific post. 我有返回数组的数组-但数组显示它将显示所有类别,而不是与该特定帖子有关的类别。
I also tried: 我也尝试过:
<?php
//list terms in a given taxonomy (useful as a widget for twentyten)
$taxonomy = 'project-type';
$tax_terms = get_terms($taxonomy);
?>
<?php
foreach ($tax_terms as $tax_term) {
echo $tax_term->name;
}
?>
And that also displays all categories instead of the ones pertaining to the post. 并且还会显示所有类别,而不是与帖子相关的类别。
Any suggestions?? 有什么建议么??
