tag list made from specific category - wordpress
I think the method you've found it's the only way you can achieve what you're looking for. Maybe you can modify some lines, but the concept is right.
at the moment i don't think there's a way to filter tags as you would using a core wordpress function.
I did not get the code above to work my installation of WordPress. I did however manage to tweak it until it worked. Here is my tweak:
$catid = get_cat_ID(single_cat_title("",false));
$catobj = get_category($catid);
$catslug = $catobj->slug;
$all_tags_arr = array();
query_posts('category_name='.$catslug);
if (have_posts()) : while (have_posts()) : the_post();
$posttags = get_the_tags();
if ($posttags) {
foreach($posttags as $tag) {
$all_tags_arr[] = $tag -> term_id;
}
}
endwhile; endif;
$tags_arr = array_unique($all_tags_arr);
$tagcloud_args = array(
'include' => implode(',',$tags_arr),
);
wp_tag_cloud( $tagcloud_args );
wp_reset_query();
Here is a much easier example.... Just change the category name and hey presto your done. The associated tags will print out in a list format.
<?php query_posts('category_name=html'); if (have_posts()) : while (have_posts()) : the_post();
$posttags = get_the_tags();
if ($posttags) {
foreach($posttags as $tag) {
$all_tags[] = $tag -> name;
}
}
endwhile; endif;
//This snippet removes any duplicates.
$tags_unique = array_unique($all_tags);
echo '<ul>';
foreach($tags_unique as $unique) {
echo '<li>'.$unique.'</li>';
}
echo '</ul>';
wp_reset_query();
?>
