    I was needing a link saying "back" that pointed to the category that the post was originally posted in. So I wrote this short plugin, I thought someone might use it.

    <?php
    /*
    Plugin Name: Parent Category
    Plugin URI:
    Description: Adds a link to the parent category in the single.php template. To use, call the_parent_category_link(); where you want the link to appear.

    function the_parent_category_link($text = "back", $selector = true)
    {
    global $post;
    if ( !isset($post->post_category) ) {
    return;
    }
    $url = get_settings('siteurl').'/index.php?cat='.$post->post_category;
    if(!$selector) {
    return $url;
    }
    else {
    echo '<a href="'.$url.'">'.$text.'</a>';
    }
    }

    ?>
