I'm trying to display a link to just the child category on a Wordpress post. For instance if the category for a post is parent > child I want to show a link to just the child category page.

I'm using code from here: Name of last category level for a post

It works perfectly but just prints the child category, how do I go about making it a link tot he child category?

 $allCat = get_the_category();
 $lastCat = array_reverse($allCat);
 echo $lastCat[0]->name;
1

You can use get_category_link() for that:

$allCat = get_the_category();
if( ! empty( $allCat ) ){
    $lastCat = array_reverse( $allCat );
    $last_cat_link = get_category_link( $lastCat[0] );
    if( ! is_wp_error( $last_cat_link ) ){
        echo '<a href="' . $last_cat_link . '">' . $lastCat[0]->name . '</a>';
    }
}

  • I tried this and it shows the correct child category but the link goes to the post, not the category page. @freejack – Tnace Oct 9 '19 at 16:48
  • I have updated the code as there was a typo in $lastCat variable. Also added extra checks to avoid errors! – freejack Oct 9 '19 at 17:00
  • That's perfect, thanks for your help! – Tnace Oct 9 '19 at 17:02
