wordpress get_categories 计数也自定义帖子类型

Question

在我的主页上，我想展示每个类别有多少帖子。所以我使用 get_categories->count 。但我有一个新闻自定义帖子类型。每个新闻项目都与一个类别相关联。那么如何从计数中排除自定义帖子类型？

这是我的代码：

$args = array(
    'type'  => 'post',
    'child_of'  => 0,
    'parent'  => '',
    'orderby'  => 'name',
    'order'  => 'ASC',
    'hide_empty'  => 0,
    'hierarchical' => 1,
    'exclude' => array(1,8),
    'include' => '',
    'number' => '',
    'taxonomy'  => array('category'),
    'pad_counts' => true
  );
$categories = get_categories( $args );

然后我在循环中使用：echo $category->count

如果我正确理解了您的问题，这应该会对您有所帮助。以下代码将列出您的所有帖子类别及其各自的帖子计数，从计数总数中省略新闻 CPT 帖子。

<?php $cats = get_categories();  // Get categories ?>

<?php if ($cats) : ?>
    <ul>
    <?php // Loop through categories to print name and count excluding CPTs ?>
    <?php foreach ($cats as $cat) { 

        // Create a query for the category to determine the number of posts
        $category_id= $cat->term_id;

        $cat_query = new WP_Query( array( 'post_type' => 'post', 
                    'posts_per_page' => -1,
                    'cat' => $category_id
        ) );
        $count = $cat_query->found_posts;

        // Print each category with it's count as a list item
        echo "<li>" . $cat->name . " (" . $count . ")</li>";

    } ?>

    <?php wp_reset_query();  // Restore global post data  ?> 
    </ul>
<?php endif; ?>
