Grab only 1 category?

    Hi,

    This is my second, hopefully quick, question that I also cannot find through search, WP or Google:

    Is there a template tag that grabs the primary category or first category assigned to a post?

    In Moveable Type, which I’m moving from, I can specify the primary category and then use it as a heading placed right above my post content. So I’m wondering what WP has that is similar. I can get output of all categories. But I want only the primary category, ideally, or the first category assigned to a post.

    Thank you for any help!

    <?php single_cat_title(''); ?>

    Yes, I did search. And I found that tag. However, it did not work in my template. It gave me a blank. So I assumed that the tag is used for some other purpose. Remember, I want the primary tag, or the first tag, assigned to my post. Since single_cat_title appears to have no values to pass (e.g., a phrase like ‘primary’ or ‘first’), I assumed that tag was a dead end.

    If you have a moment, can you tell me if WordPress uses the concept of a “primary category” like MoveableType? Or are all categories equal?

    Thank you!

    Hum… I could be wrong, but no, in wordpress, the concept of “primary category” doesn’t exist…

    If you check many category for a post, this post will belong “equally” to all these category.

    You can make a hierarchy of categories if you use “child categories” and “parent categories”…

    Now, for <?php single_cat_title(''); ?>, this tag must be used outside the loop, in archive or category template, to display the category you are browsing. From what I can tell, you wont see anything with this tag in a single post page.

    To display the “first” category of a post, inside the loop of a single post page, you can use this piece of code :

    <?php
$category = get_the_category();
echo $category[0]->cat_name;
?>

    Hope this can help you.

    Thanks alot, Simon, for the code! This works well enough that I can play with the results. I’ll have to rethink my strategy for organizing posts to conform to WordPress.

    This thread can be marked as resolved. Thanks for the help!

    My pleasure Fredhead…

    To mark this thread as resolved, look at the right sidebar at the top of this page. You should see the option to do so.
