我有一个短代码，它为post category slug和returns以及post列表接受1个参数。

    //[list-products] creates the product table in the wholesale page, can be used to create a table list of any category

function list_products_func ( $atts ) {

$a = shortcode_atts( array (
  \'category\' => \'\',
), $atts);

  $args = array(
      \'posts_per_page\' => -1,
      \'tax_query\' => array(
          \'relation\' => \'AND\',
          array(
              \'taxonomy\' => \'product_cat\',
              \'field\' => \'slug\',
              \'terms\' => $a[\'category\']
          )
      ),
      \'post_type\' => \'product\',
      \'orderby\' => \'title,\'
  );

  $products = new WP_Query( $args );
  echo "<table>";
  while ( $products->have_posts() ) {
      $products->the_post();
    $product = new WC_Product(get_the_ID());
      ?>
          <tr class="product-list-item">
              <td><a href="<?php the_permalink(); ?>">
                  <?php the_title(); ?>
              </a></td>
              <td>
                  <?php echo get_the_excerpt(); ?>
              </td>
              <td>
                  <?php echo $product->get_price_html(); ?>
              </td>
          <td>
          <?php echo woocommerce_quantity_input(
            array(
                \'min_value\' => 1,
                \'max_value\' => $product->backorders_allowed() ? \'\' : $product->get_stock_quantity(),
            )); ?>
          </td>
          <td>
          <?php echo woocommerce_template_loop_add_to_cart(); ?>
          </td>
          </tr>
      <?php
  }
  echo "</table>";
}
add_shortcode ( \'list_products\' , \'list_products_func\' );

我希望它能够采取任何数量的类别，并返回符合这两个类别的帖子。在本用例中，咖啡经销商使用它来展示WooCommerce产品，这些产品的类别为wholesale 和他们的咖啡子类别之一distinct-well-defined 或者别的什么。

它的使用方式是[list-products CAT1 CAT2]

我试着用逗号键入短代码，希望代码能正确解释，但没有成功。

任何帮助都将不胜感激。

事实证明，我实际上需要它来过滤产品，所以它只显示两个类别的产品，而不显示两个类别中的所有产品。

<?php
function list_products_func($atts) {

   $a = shortcode_atts(array(
      \'categories\' => \'\',
   ), $atts);

   // Check for multiple categories by comma
   if ( strpos( $a[\'categories\'], \',\' ) !== false ) {
      $terms = explode( $a[\'categories\'] );
   } else {
      $terms = $a[\'categories\'];
   }

   $args = array(
      \'posts_per_page\'  => -1,
      \'tax_query\'       => array(
         \'relation\'     => \'AND\',
         array(
            \'taxonomy\'  => \'product_cat\',
            \'field\'     => \'slug\',
            \'terms\'     => $terms // Your exploded terms array 
         )
      ),
      \'post_type\' => \'product\',
      \'orderby\'   => \'title,\'
   );

   $products = new WP_Query($args);
   echo "<table>";
   while ($products->have_posts()) {

      $products->the_post();
      $product = new WC_Product(get_the_ID()); ?>
      <tr class="product-list-item">
         <td><a href="<?php the_permalink(); ?>"><?php the_title(); ?></a></td>
         <td><?php echo get_the_excerpt(); ?></td>
         <td><?php echo $product->get_price_html(); ?></td>
         <td>
            <?php echo woocommerce_quantity_input(
            array(
               \'min_value\' => 1,
               \'max_value\' => $product->backorders_allowed() ? \'\' : $product->get_stock_quantity(),
            )); ?>
         </td>
         <td><?php echo woocommerce_template_loop_add_to_cart(); ?></td>
      </tr>
      <?php

   }
   echo "</table>";
}
add_shortcode(\'list_products\', \'list_products_func\');
?>

//Generates an array of tax_query arguments
  $query_args = array ();
  foreach ( $terms as $term ) {
    array_push( $query_args, array (
          \'taxonomy\' => \'product_cat\',
              \'field\' => \'slug\',
              \'terms\' => $term
          )
    );
  }

  $args = array(
      \'posts_per_page\' => -1,
      \'tax_query\' => array(

          $query_args
