具有帖子计数和多个父项的分类菜单

我正在使用WordPress 3.1.3，并试图制作一个“产品”菜单，其中每个类别都有帖子数量。像这样：

新车（4）宝马（2）福特（1）日产（1）二手车（10）宝马（3）福特（1）日产（6）为此，我创建了定制post类型Cars 和分类法Type 和Brand. 不确定这是否是最好的方法，但下面是我的代码：

<?php $auto_types = get_terms(\'type\', \'hide_empty=1\'); ?>
<ul>
<?php foreach( $auto_types as $auto_type ) : ?>
  <li>
    <a href="<?php echo get_term_link( $auto_type->slug, \'type\' ); ?>">
      <?php echo $auto_type->name; ?> (<?php echo $auto_type->count; ?>)
    </a>
                <?php
                $terms = get_terms(\'brand\');
                $count = count($terms);
                if($count > 0) :
                    ?>
                     <ul>
                        <?php foreach ($terms as $term) : ?> 

                        <li>
                            <a href="/?type=<?php echo $auto_type->slug ?>&brand=<?php echo $term->slug ?>">
                                    - - <?php echo $term->name; ?> (<?php echo $term->count; ?>)
                            </a>
                        </li>
                        <?php endforeach ?>
                    </ul>
                    <?php endif ?>

    </li>           
<?php endforeach ?>
</ul>

所以我的问题是：

这是一个好方法吗Edit - 我已经设法解决了第二个问题，但我仍然不确定这是否是一个好方法。以下是新代码：

<?php $auto_types = get_terms(\'type\', \'hide_empty=1\'); ?>
    <ul>
    <?php foreach( $auto_types as $auto_type ) : ?>
        <li>
        <a href="<?php echo get_term_link( $auto_type->slug, \'type\' ); ?>"> 
            <?php echo $auto_type->name; ?>
        </a>
        <?php $auto_brands = get_terms(\'brand\', \'parent=0\' ); ?>
            <ul>
                <?php foreach ($auto_brands as $auto_brand) : ?>
                    <?php $brand_filter[\'tax_query\'] = array(
                            \'relation\' => \'AND\',
                            array(
                                \'taxonomy\' => \'type\',
                                \'terms\' => array($auto_type->slug),
                                \'field\' => \'slug\',
                            ),
                            array(
                                \'taxonomy\' => \'brand\',
                                \'terms\' => array($auto_brand->slug),
                                \'field\' => \'slug\',
                            ),
                        );
                    $tax_query = new WP_Query($brand_filter);
                        $count = 0;
                    if ( $tax_query->have_posts() ) : while ( $tax_query->have_posts() ) : $tax_query->the_post();
                        $count++;
                    endwhile; endif; wp_reset_postdata();
                        if ( $count > 0 ) : ?>
                            <li>
                                <a href="/?type=<?php echo $auto_type->slug ?>&brand=<?php echo $auto_brand->slug ?>">
                                    - - <?php echo $auto_brand->name; ?> (<?php echo $count; ?>)
                                </a>
                            </li>
                <?php endif; endforeach ?>
            </ul>                 
        </li>           
    <?php endforeach ?>
    </ul>

Edit 2 - 已更改query_posts() 方法到wp_query() （多亏了VicePrez），但使用query只获取正确的帖子计数是有效的还是有更好的方法来创建此菜单？

<?php $auto_types = get_terms(\'type\', \'hide_empty=1\'); ?> <ul> <?php foreach( $auto_types as $auto_type ) : ?> <li> <a href="<?php echo get_term_link( $auto_type->slug, \'type\' ); ?>"> <?php echo $auto_type->name; ?> </a> <?php $auto_brands = get_terms(\'brand\', \'parent=0\' ); ?> <ul> <?php foreach ($auto_brands as $auto_brand) : ?> <?php $brand_filter[\'tax_query\'] = array( \'relation\' => \'AND\', array( \'taxonomy\' => \'type\', \'terms\' => array($auto_type->slug), \'field\' => \'slug\', ), array( \'taxonomy\' => \'brand\', \'terms\' => array($auto_brand->slug), \'field\' => \'slug\', ), ); $tax_query = new WP_Query($brand_filter); if ( $tax_query->have_posts() ) : $count = 1; while ( $tax_query->have_posts() ) : $tax_query->the_post(); if ( $count >= 1 ) { ?> <li> <a href="/?type=<?php echo $auto_type->slug ?>&brand=<?php echo $auto_brand->slug ?>"> - - <?php echo $auto_brand->name; ?> (<?php echo $count; ?>) </a> </li> <? } $count++; endwhile; wp_reset_postdata(); endif; endforeach ?> </ul> </li> <?php endforeach ?> </ul>

<?php $auto_types = get_terms(\'type\', \'hide_empty=1\'); ?> <ul> <?php foreach( $auto_types as $auto_type ) : ?> <li> <a href="<?php echo get_term_link( $auto_type->slug, \'type\' ); ?>"> <?php echo $auto_type->name; ?> </a> <?php $auto_brands = get_terms(\'brand\', \'parent=0\' ); ?> <ul> <?php foreach ($auto_brands as $auto_brand) : ?> <?php $brand_filter = array( \'posts_per_page\' => \'-1\', \'tax_query\' => array( \'relation\' => \'AND\', array( \'taxonomy\' => \'type\', \'field\' => \'slug\', \'terms\' => array($auto_type->slug), ), array( \'taxonomy\' => \'brand\', \'field\' => \'slug\', \'terms\' => array($auto_brand->slug), ) ) ); $tax_query = new WP_Query($brand_filter); $count = 0; if ( $tax_query->have_posts() ) : while ( $tax_query->have_posts() ) : $tax_query->the_post(); $count++; endwhile; endif; wp_reset_postdata(); if ( $count > 0 ) : ?> <li> <a href="/?type=<?php echo $auto_type->slug ?>&brand=<?php echo $auto_brand->slug ?>"> - - <?php echo $auto_brand->name; ?> (<?php echo $count; ?>) </a> </li> <?php endif; endforeach ?> </ul> </li> <?php endforeach ?> </ul>

Menu API not switching menus?

我正在使用菜单API，我想切换到其他菜单，但出于某种原因，它保留了第一个菜单这是我的密码在函数中。php add_action( \'init\', \'register_my_menus\',10 ); function register_my_menus() { register_nav_menu(\'main-navigation\', \'Main Navigation\'); } 下面是我的主题文件（header.ph
