Hi,

I'm trying to get the tags for the current post outside the loop (for usage in a widget). I can't find any way to do it and would appreciate any help i can get.

To echo a list of tags from a particular post outside the Loop, you can set $post global, then do a foreach loop to echo the tags as normal.

For example, I use this loop to display post tags as meta keywords in my header if the page is a single post page.
```
<?php
   global $post;
   foreach(get_the_tags($post->ID) as $tag) {
      echo $tag->name . ', ';
   }
?>
```

Cool stuff.

This is a bit of code I have been working on. In this example the rtrim function removes the last comma of the last word in the list:
```
<?php
$posttags = get_the_tags();
    foreach((array)$posttags as $tag) {
        $show_tags .= $tag->name . ',';
    }{
$rel_art .= rtrim($show_tags , ',');{
}
print $rel_art;
}
?>
```
Based on the examples shown here:
