How do I display all tags (linked) from all posts, inline, with a separator?
I have this code but it has no separator
<?php
$tags = get_tags();
$html = '<div class="post_tags">';
foreach ( $tags as $tag ) {
$tag_link = get_tag_link( $tag->term_id );
$html .= "<a href='{$tag_link}' title='{$tag->name} Tag' class='{$tag->slug}'>";
$html .= "{$tag->name}</a> ";
}
$html .= '</div>';
echo $html;
?>
e.g.
