Now that WordPress comes with tag support, you might have posts that you only want tagged and not categorised. To set that up in the Connections theme, you'll need to set up a category that you don't want displayed (I used 'Uncategorised' and no, I don't live in America, thank you), and edit post.php.
If you enabled tags by following my instructions for enabling tags in Connections, you'll have some code like this:
Posted by under
The call to the function thecategory() outputs a link to the category page for each category under which your post is filed. To output categories conditionally you don't want to output them directly, so you need to use the getthe_category function, which returns an array of category objects. I'll ignore the fact that the function calls should really be plural. Replace the code above with the following code.
Posted by
cat_name == 'Uncategorised')) {
echo " under";
$category_url = get_option('siteurl') . '/category/';
foreach ($categories as $category) {
echo " category_nicename}\">";
echo "{$category->cat_name}";
}
}
the_tags(' tagged ', ', ', '');
edit_post_link(' (edit)');
?>
Unless there's only one category and it's the one you don't want to display, you want to output the categories. Basically, you need to manually build what thecategory builds automatically. Again, I'll ignore the terrible category method naming, some cat others category_.
