Display tags only if assigned to more than one post

to only show if there are other posts with the same tag

<?php
$tags = wp_get_post_tags($post->ID);
  if ($tags) {
    foreach($tags as $tag) {
      if ($tag->count > 1) {
        echo '' . $title . '<a href="' . get_term_link( $tag->term_id, 'post_tag' ) . '" title="' . sprintf( __( "View all posts in %s" ), $tag->name ) . '" ' . '>' . $tag->name.'</a> is assigned to ' . $tag->count . ' posts.
 ';
      }
    }
  }
?>

Thank you!! Works perfectly

Great! But where to put the code?

First review Template Hierarchy…your theme’s index.php or archive.php or category.php are possibilities.
