   How would I go about showing all the tags that are used in a certain category and just that category?

   tag: tdo-tag-fixes

   there are 2 different functions in here. not perfect. will leave trailing commas and write duplicates if there are any. It's a start.

   <!-- here -->
   <div>
   <ul>
   <?php
   // this will build a list of all categories and then all posts in them and list all tags used in each post
   foreach (get_categories(array('hide_empty'=>true)) as $category)
   {
   $catid = $category->cat_ID;
   global $post;
   $myposts = get_posts('category='.$catid);
   echo '<li>' . $category->cat_name . "\n";
   echo '<ul>' . "\n";
   foreach($myposts as $post) {
   echo '<li>';
   foreach(get_the_tags($post->ID) as $tag) {
   	echo $tag->name . ', ';
   	}
   
   echo '</li>' . "\n";
   }
   echo '</ul>' . "\n";
   echo '</li>' . "\n";
   }
   ?>
   </ul>
   
   <ul>
   <?php
   // a specific category
   global $post;
   $myposts = get_posts('category=wordpress');
   echo '<li>' . $category->cat_name . "\n";
   echo '<ul>' . "\n";
   foreach($myposts as $post) {
   echo '<li>';
   foreach(get_the_tags($post->ID) as $tag) {
   	echo $tag->name . ', ';
   	}
   echo '</li>' . "\n";
   }
   echo '</ul>' . "\n";
   echo '</li>' . "\n";
   ?>
   </ul>
   </div>
   <!-- here -->
