获取多个帖子类型和分类法

Question

I want to display latest news/alerts post on my homepage and I need some help.

I am currently only displaying news with post post-type using below code. This is working perfectly. The problem occurs when I want to use more than one post-type. once I modify as 'post_type' => array('post','blog'), nothing appears. The reason why it does not show is $term = get_the_category();. Once I remove this whole section for color with <a></a>. It works perfectly.

So I believe I have to specify the taxonomies. Because in Post I have tax as category and in Blog I have tax as blog-category. I could not get these two in same time.

So how can I call two taxonomies in $term = get_the_category();

Thank you from now

Cannot add a comment, so I'll post it as an answer. Try:

<?php
      $term = get_the_category();
      if ( ! empty( $term ) ) {
          $term = $term[0];
          $color = get_term_meta($term->term_id, 'color', true);
          ?>
          <a href="<?php echo get_term_link($term) ?>" class="category" style="background-color: <?php echo $color ?>">
          <?php echo $term->name ?>
          </a>
          <?php
       }
       ?>
       <h2 class="title">
              <a href="<?php the_permalink() ?>" class="underline"><?php the_title() ?></a>
       </h2>

This will at least prevent from showing / executing when $color is not set.
