I currently have the following trying to avoid showing tags (the icon in this case) when there aren't any, but the icon continues to show up. Any thoughts?

<?php if ( is_singular() && function_exists('the_tags') ) : ?> 
    <p><i class="icon-tags"></i><?php the_tags('', ', ', ' '); ?></p>
<?php endif; ?>

Get a string value for the tags and print it only if there are tags:

$tags = get_the_tag_list('', ', ', ' ');

if ( "" !== trim( $tags ) )
{
    echo "<p><i class='icon-tags'></i>$tags</p>";
}

  • Your icon is defined in your css for the icon-tags class. So your code still displayed the HTML. @toscho code doesn't echo the HTML unless you have tags.

  • @Stephen I made an edit, the HTML should be printed now only if there are tags.

  • Actually I didn't catch the error. Was referring to the OP; but yes your edit is correct of course.

  • You could also use the OP's the_tags('', ', ', ' '); inside the conditional (although it would be redundant). Nov 25, 2012 at 18:33

you could also add the html into the 'before' parameter of the_tags()

for example reducing your whole code to one line:

<?php if ( is_singular() ) the_tags('<p><i class="icon-tags"></i>', ', ', '</p>'); ?>`

  • +1 For very short strings this is indeed the most pragmatic approach. :)
