获取分类(cat&term)信息

WordPress get_terms()的使用方法：

例1.输出term相关信息

<ul class="products">
                <?php  $terms = get_terms('category',array(
    'with_thumbnail' => true,
    'hide_empty' => false,
)   );
if ( ! empty( $terms ) && ! is_wp_error( $terms ) ){
    foreach ( $terms as $term ) {?>
                <li>
                    <a href="<?php  echo get_term_link($term->term_id) ?>">
                        <div class="term-pic">
                            <?php the_term_thumbnail($term ->term_id, 'post-thumbnail');?>
                        </div>
                        <div>
                            <h3>
                                <?php echo $term->name;?>
                            </h3>
                            <div>
                                <?php echo $term->description;?>
                            </div>
                        </div>
                    </a>
                </li>
                <?php    }
}?>
            </ul>

例2.循环term显示相应的文章

        <?php
 $terms = get_terms([
    'taxonomy' => 'area',
    'hide_empty' => true,
]);
   foreach( $terms as $term):?>
            <div class="area-part">
                <h3>
                    <?php echo $term->name;  ?>
                </h3>
                <ul class="posts-list">
                    <?php
 $args = array(
    'post_type'=>'store',
    'tax_query' => array(
		array(
            'taxonomy' => 'area',
            'field' => 'id',
			'terms'    => $term->term_id,
		),
	),
    ); 
    $query = new WP_Query( $args );
    if( $query->have_posts()):
     while($query->have_posts()):$query->the_post();                         
get_template_part('partials/content','shopList');
//Restore orginial post Data
    wp_reset_postdata();  
    endwhile;?>
                </ul>
                <?php endif;?>
            </div>
            <?php endforeach;
    ?>
