List all taxonomy terms / Show links if posts are attached, else names

by

I’m looking for a way to list all the terms from a custom taxonomy. Only the terms that have posts attached to it should have links to the archive page. If there are no posts attached it should only show the names.

Any ideas? Thanks!

<?php
$taxonomy = 'cat';
$queried_term = get_term_by( 'slug', get_query_var($taxonomy) );
$terms = get_terms($taxonomy);
if ( $terms !== 0 ) {
    foreach ( $terms as $term ) {
        echo $term->name . ", ";
    }
}
if ( $terms > 0 ) {
    foreach ( $terms as $term ) {
        echo '<li><a href="' . $term->slug . '">' . $term->name .'</a></li>';
    }
}
?>

I didn’t understood your question well, but try this. Explanation is in the comments.

// your taxonomy name
$tax = 'post_tag';

// get the terms of taxonomy
$terms = get_terms( $tax, [
  'hide_empty' => false, // do not hide empty terms
]);

// loop through all terms
foreach( $terms as $term ) {

  // if no entries attached to the term
  if( 0 == $term->count )
    // display only the term name
    echo '<h4>' . $term->name . '</h4>';

  // if term has more than 0 entries
  elseif( $term->count > 0 )
    // display link to the term archive
    echo '<h4><a href="'. get_term_link( $term ) .'">'. $term->name .'</a></h4>';

}

Hope it helped you.
