get all tags of published posts Wordpress

问题:

How do I fetch all tag names (with ID and count) from all published posts?

I know there is wp_tag_cloud but I only want an array of all tags.

回答1:

Check out get_terms() to retrieve the terms in a given taxonomy:

Examples:

$categories = get_terms( 'category',    'orderby=count&hide_empty=0' );

$tags       = get_terms( 'post_tag',    'orderby=count&hide_empty=0' );

$myterms    = get_terms( 'my_taxonomy', 'orderby=count&hide_empty=0' );

This works for me along with tags count.

<?php
$tags = get_tags();
if ($tags) {
?><ul class="tags"><?php
foreach ($tags as $tag) {
    echo '<li><a href="' . get_tag_link( $tag->term_id ) . '" 
          title="' . sprintf( __( "View all posts in %s" ), $tag-
          >name ) . '" ' . '>' . $tag->name.' (' . $tag->count . ')</a></li>';
}
echo '<li><a href="#">View All</a><span class="arrow"></span>
</li>'; ?></ul>
<?php }?>
