WordPress插件"Search and Filter" - 在结果中显示自定义帖子类型类别.php文件

Question

我正在从Search and Filter Pro插件(WordPress(中操作results.php文件。我还试图显示每个自定义帖子类型的类别。但我在前端看到的只是"；数组"；而不是类别名称。这是我当前的代码：

if ( $query->have_posts() )
{
?>
<div class="pagination">

<div class="nav-previous"><?php next_posts_link( 'Older posts', $query->max_num_pages ); ?></div>
<div class="nav-next"><?php previous_posts_link( 'Newer posts' ); ?></div>
<?php
/* example code for using the wp_pagenavi plugin */
if (function_exists('wp_pagenavi'))
{
echo "<br />";
wp_pagenavi( array( 'query' => $query ) );
}
?>
</div>
<?php
while ($query->have_posts())
{
$query->the_post();

$post_id = get_the_ID();
$post_category = get_the_category();
$description = get_field('product_description', $post_id);

?>
<div class="product-div">

<?php 
if ( has_post_thumbnail() ) {
echo '<p>';
?>
<?php the_post_thumbnail("small");?>
<?php
echo '</p>';
}
?>
<h3><?php echo $post_category; ?></h3>
<h2><?php the_title(); ?></h2>
<?php echo $description;?>

</div>

<?php
}
?>
<?php
}
else
{
echo "No Results Found";
}
?>

我做错了什么？

Answer 1

查看函数get_the_category，根据引用页面返回一个WP_Term对象数组。试试<?php echo $post_category[0]->name; ?>，或者如果帖子分配了多个类别，你可以循环浏览，比如：

foreach($post_category as $category){
echo $category->name;
}
