    Hello,

    Thank you for the great plugin!

    I am trying to get the name of the permalink category to display, but the following code does not work:
    <div class="featured-cat"><?php $category = get_the_category(); echo $category[0]->cat_name; ?></div>

    The above code just displays the first category, which is ordered alphabetically. Is there any way I can get the main permalink category for display purposes? Something like what Yoast has done here: https://www.joshuawinn.com/using-yoasts-primary-category-in-wordpress-theme/ for example.

    Thank you in advance,
    Donna

  • You can do this:

    <?php
  setup_postdata($post);
  $perma_cat = get_post_meta($post->ID , '_category_permalink', true);
  if ( $perma_cat != null ) {
    $cat_id = $perma_cat['category'];
    $cat = get_category($cat_id);
    $category_link = get_category_link($cat_id);
    $category_name = $cat->name;
  } else {               
    $cat = get_the_category();
    $category_link = get_category_link($category->term_id);
    $category_name = $cat[0]->cat_name;
  }
?>
<a href="<?php echo $category_link ?>"><?php echo $category_name ?></a>

    Slightly updated version with a fix for the fallback category link:

    <?php
  $perma_cat = get_post_meta($post->ID , '_category_permalink', true);
  if ( $perma_cat != null ) {
    $cat_id = $perma_cat['category'];
    $category = get_category($cat_id);
  } else {
    $categories = get_the_category();
    $category = $categories[0];
  }
  $category_link = get_category_link($category);
  $category_name = $category->name;  
?>                                   
<a href="<?php echo $category_link ?>"><?php echo $category_name ?></a>

    Sorry, I am noticing the following in my error logs:
    [Sat Apr 22 09:42:13 2017] [error] PHP Warning: Illegal string offset ‘category’ in on line 29

    Which is this line of code:
    $cat_id = $perma_cat[‘category’];

    OK I added the following and the error seems to have stopped:
    if ( $perma_cat != null && is_array($perma_cat)) {

    So that it checks to make sure it’s an array.

    Thanks again!
    Donna
