limit a list of tags to one category [closed]

Question

Sorry if this has already been asked, but I am attempting to limit a list of tags to one category, in a couple different spots on my web page. I have this code:

    <?php
    $tags = get_tags();
    $tags_count = count($tags);
    $percolumn = ceil($tags_count / 3);

    for ($i = 0;$i < $tags_count;$i++):
    if ($i < $percolumn):
    $tag_left .= '
<li><a href="'. get_tag_link($tags[$i]->term_id) . '"rel="tag">' . $tags[$i]->name .'</a></li>
    ' . "\n";
    elseif ($i >= $percolumn && $i < $percolumn*2):
    $tag_mid .= '
<li><a href="'. get_tag_link($tags[$i]->term_id) . '"rel="tag">' . $tags[$i]->name .'</a></li>
    ' . "\n";
    elseif ($i >= $percolumn*2):
    $tag_right .= '
<li><a href="'. get_tag_link($tags[$i]->term_id) . '"rel="tag">' . $tags[$i]->name .'</a></li>
    ' . "\n";
    endif;
    endfor;
    ?>
    <ul>
    <?php echo $tag_left; ?>
    </ul>

    <ul>
    <?php echo $tag_mid; ?>
    </ul>

    <ul>
    <?php echo $tag_right; ?>
    </ul>

How can I leverage this, and restrict the query to just one category.

Answer 1

I was trying to do this exact thing a day or two ago. I ended up using the plugin/widget: http://wordpress.org/extend/plugins/simple-taxonomy/

It allows you to create custom taxonomies, and includes a tag cloud/list limited to whatever category you choose. And other things, but I've only used those two. Easy to style with CSS and worked right away.

Hope that helps.

You can easily do this without a plugin, but you would need to get all the posts with that specific category and then loop through those to get the tags of each of those specific posts.
