カスタムカテゴリIDでカスタム投稿を取得する方法

Question

カスタムカテゴリIDでカスタム投稿を取得しようとしています。カテゴリに付いた投稿データ。ただし、投稿カテゴリを1つ選択すると、自動的に他のカテゴリで選択されます。私は別のカテゴリに異なる投稿を割り当てることができません。ここで

$args = array( 
     'post_type'  => 'portfolio', 
     'posts_per_page' => 5 
    ); 

    $loop = new WP_Query($args,'category_name=categories'); 

    while ($loop->have_posts()) : $loop->the_post(); 
     echo '<div class="col-1-3">'; 
     ?><?php $thumbnail = wp_get_attachment_image_src(get_post_thumbnail_id($post->ID), "size");?> 
     <div class="wrap-col"> 
         <div class="item-container"> 
          <a class="fancybox" href="<?php echo $thumbnail[0]; ?>" data-fancybox-group= gallery> 

          <div class="overlay text-center"> 
          <div class="overlay-inner"> 
           <h4>BAKER CANISTER PUMP</h4> 
          </div> 
          </div><img src="<?php echo $thumbnail[0];?>"></a> </div> 
         </div> 
     <?php echo '</div>'; 
    endwhile; wp_reset_postdata();?>

<?php 

//loop the names of the slugs for the portfolio_categories 
$terms = get_terms(array ('taxonomy' => 'portfolio_categories', 'hide_empty' => false, 'parent' => 0, 'orderby' => 'date', 'order' => 'DESC')); 
foreach ($terms as $term) { 
    $slug = $term->slug; 

    $posts_args = array(
    'post_type'   => porfolio, 
    'posts_per_page' => -1, 
    'tax_query'   => array(
     'relation' => 'AND', 
     array (
      'taxonomy' => 'portfolio_categories', 
      'field' => 'slug', 
      'terms' => $slug, 
    ) 
    ), 
); 
    $posts_query = new WP_Query($posts_args); 
    if($posts_query->have_posts()): 
    echo '<div id="' . $slug . '"> 
     <h1 class="text-center">' . $term->name . '</h1> 
      while($posts_query->have_posts()): $posts_query->the_post(); 
       echo '<div>' . get_the_content() . '</div>'; 
      endwhile; 
    echo '</div>'; 
    endif; 
    } 
?>
