I have this...

$args = array('child_of' => 3422 );
$categories = get_categories( $args );
foreach($categories as $category) { 
    echo '<a href="' . get_category_link( $category->term_id ) . '" title="' . sprintf( __( "View all members in %s" ), $category->name ) . '" ' . '>' . $category->name.'</a> '; 
}

I can't find a way to add a separator between each term?

• categories
• list
• wp-parse-args

• What is it you have now and what is the desired result? You can add a seperator via CSS also. Just add a border-left of border-right. – Refilon Commented Sep 24, 2019 at 11:30
• @Refilon That's not a true separator as it will occur outside the terms. A separator only appears within the terms. – Pete Commented Sep 24, 2019 at 11:56

With the code that you're using your just going to get a list of words that are links to the categories.

You are facing two problems, adding the separator and also making sure the separator isn't added to to the last item.

You have a couple options: With your code:

$args = array('child_of' => 3422 );
$categories = get_categories( $args );
$i = 1;
$separator = ', '; // Include a separator to separate the category
$count_category = count($categories);   // get total category value  to limit the separator for last
foreach($categories as $category) { 
    if ($i != 1) {
       echo $separator;
    }
    if($i< $count_category && $i!=1){
      echo '.';
    }
    echo '<a href="' . get_category_link( $category->term_id ) . '" title="' . sprintf( __( "View all members in %s" ), $category->name ) . '" ' . '>' . $category->name.'</a> ';  
  $i++;
}

or you can do it using

get_the_category_list( string $separator = '', string $parents = '', int $post_id = false )

$args = array('child_of' => 3422 );
echo get_the_category_list (',' );
