显示这些类别中的子类别和产品的列表

  • 772

玩的很开心！

任务是在当前嵌套级别显示子类别和这些类别中的产品的列表。

有一个代码显示忽略活动类别的所有商店类别。

                $args = array(

   'number'     => $number,

   'orderby'   => 'title',

   'order'     => 'ASC',

   'hide_empty' => $hide_empty,

   'include'   => $ids,
                  


);

$product_categories = get_terms( 'product_cat', $args );

$count = count($product_categories);

if ( $count > 0 ){

   foreach ( $product_categories as $product_category ) {

       echo '<h4><a href="' . get_term_link( $product_category ) . '">' . $product_category->name . '</a></h4>';

       $args = array(

           'posts_per_page' => -1,

           'tax_query' => array(

              'relation' => 'AND',

               array(

                   'taxonomy' => 'product_cat',

                   'field' => 'slug',

                   // 'terms' => 'white-wines'

                   'terms' => $product_category->slug

                )

           ),

           'post_type' => 'product',

           'orderby' => 'title,'

       );

       $products = new WP_Query( $args );

       echo "<ul>";

       while ( $products->have_posts() ) {

           $products->the_post();

           ?>

               <li>

                   <a href="<?php the_permalink(); ?>">

                       <?php the_title(); ?>

                   </a>

               </li>

           <?php

       }

       echo "</ul>";

   }

}

?>

有个理解是需要获取活动类别的ID，获取我需要的列表，但是我的php知识不足以实现这个。我挖出了这样一个代码，还有待了解如何在上述代码中正确应用它。

$current_term = get_queried_object();
    $terms = get_terms( [
        'taxonomy' => [ 'product_cat' ],
        'parent'         => $current_term->term_id,
    ] );
var_dump( $terms );

我希望得到您的提示，结果应该类似于以下结构：

商店 > 产品（活跃类别）

水果（儿童类别）

  • 香蕉（产品）
  • 苹果
  • 梨

蔬菜

  • 土豆
  • 洋葱
  • 胡椒

  1. 像这样试试

    
<?php
$args = array(
                                 'orderby'   => 'title',
                                 'order'     => 'ASC',
                                 'hide_empty' => false,
                                 'parent' => 0

);

$product_categories = get_terms( 'product_cat', $args );

$count = count($product_categories);

if ( $count > 0 ){

   foreach ( $product_categories as $product_category ) {

        echo '<h4><a href="' . get_term_link( $product_category ) . '">' . $product_category->name . '</a></h4>';
       
        $args = array(
                                'taxonomy' => 'product_cat',
                                'hide_empty' => false,
                                'parent' => $product_category->term_id,
                                'orderby'   => 'title',
                                'order' => 'ASC'
                             );

       $subcats = get_terms($args);    
       
       foreach ($subcats as $subcat ) :
       
             echo ' - <h5><a href="' . get_term_link( $subcat ) . '">' . $subcat->name . '</a></h5>';
             
             $args = array(
                             'posts_per_page' => -1,
                             'tax_query' => array(

                                array(
                                    'taxonomy' => 'product_cat',
                                    'field' => 'term_id',
                                    'terms' => $subcat->term_id

                                )

                            ),
                            'post_type' => 'product',
                            'orderby' => 'title',
                            'post_status' => 'publish'
                          );

            $products = new WP_Query( $args );

             echo "<ul>";

            while ( $products->have_posts() ) {

                $products->the_post();

                ?>

               <li>

                   <a href="<?php the_permalink(); ?>">

                       <?php the_title(); ?>

                   </a>

               </li>

                <?php

            }
            
            wp_reset_postdata();

            echo "</ul>";

       endforeach;
   }
}

    使用 get_queried_object，可以获得当前类别的对象数组。在参数中，我们使用'parent' => $current_term->term_id,

    $current_term = get_queried_object();

$args = array(
    'number'     => $number,
    'orderby'   => 'title',
    'order'     => 'ASC',
    'hide_empty' => $hide_empty,
    'include'   => $ids,
    'parent'   => $current_term->term_id,               
);

$product_categories = get_terms( 'product_cat', $args );

$count = count($product_categories);

if ( $count > 0 ){

   foreach ( $product_categories as $product_category ) {

       echo '<h4><a href="' . get_term_link( $product_category ) . '">' . $product_category->name . '</a></h4>';

       $args = array(

           'posts_per_page' => -1,
           'tax_query' => array(
              'relation' => 'AND',

               array(

                   'taxonomy' => 'product_cat',
                   'field' => 'slug',
                   // 'terms' => 'white-wines'
                   'terms' => $product_category->slug

                )

           ),

           'post_type' => 'product',
           'orderby' => 'title,'

       );

       $products = new WP_Query( $args );

       echo "<ul>";

       while ( $products->have_posts() ) {

           $products->the_post();

           ?>

               <li>

                   <a href="<?php the_permalink(); ?>">

                       <?php the_title(); ?>

                   </a>

               </li>
               
           <?php
       }
       echo "</ul>";
   }
}
