cpatienceI need some assistance listing tags of posts alphabetically. Right now I use a category page to list a unique instance of the tag associated with the posts within the category.
For example, a coupon post is created with the category clothing and with the tag 'Sears.' For the Clothing category page, I list the tags for all of the posts, such as 'Sears', 'Kmart', etc.
Currently I'm using the following code which works, but I'd like to sort these tags alphabetically.
<?php
$project_query = query_posts($query_string . '&orderby=name&order=asc&posts_per_page=-1');
while (have_posts()) : the_post();
$posttags = get_the_tags();
if ($posttags) {
foreach($posttags as $tag) {
$all_tags_arr[] = $tag -> name; //USING JUST $tag MAKING $all_tags_arr A MULTI-DIMENSIONAL ARRAY, WHICH DOES WORK WITH array_unique
}
}
endwhile;
?>
<?php if ( is_array($all_tags_arr) && count($all_tags_arr) > 0 ): ?>
<ul>
<?php
$tags_arr = array_unique($all_tags_arr); //REMOVES DUPLICATES
foreach( $tags_arr as $tag ):
$el = get_term_by('name', $tag, 'post_tag');
$arr[] = '"tag-'.$el->slug.'"';
?>
<li><a href="<?php echo get_bloginfo('url'); ?>/?tag=<?php echo $el->slug; ?>" id="taglink-tag-<?php echo $el->slug; ?>" rel="tag-<?php echo $el->slug; ?>"><?php echo $el->name; ?></a> </li>
<?php endforeach; ?>
</ul><?php endif; ?>I'm guessing that somehow I need to sort $el alphabetically, but I'm not sure how. Any ideas?
