Show archives of current post category only

Thanks Moshu, that was a helpful article. However I don’t know how to use correct php code to get the category of the post.

For example:
} elseif (is_category()) {
// we're looking at a single category view, so let's show _all_ the categories
echo "<ul>";
wp_list_cats ('optionall=0&sort_column=name&list=1&children=1&hierarchical=1');
echo "</ul>";

What code will get the category of the post currently being viewed? Is it: (<?php the_category_ID(echo); ?> ? If so, where does that go in the above argument?

Thanks for any and all help!

Moshu, your code idea is pretty much what I’m thinking. Where I get stuck is in the “show stuff” part. The “stuff” I would like to show is [I believe] a get_archive function, to display the titles of posts in the same category X. However, I can’t figure out how to call a list of post titles based on the category ID of the post being viewed.

I feel like I have tried just about everything!!

I should also note that the above code, is_category(x) displays the condition only on category archive pages. I am specifically interested in creating a condition that would occur on a single post (is_single) of a particular category.

[Sorry for the multiple posts here; it’s sorta late and I’m trying to provide as much info on my problem as possible!!] Thanks again for any help!! 🙂

Moshu, THANKS!!! 🙂 That looks really promising! I still need some code help to figure out how to arrange everything correctly, though.

My guess:

elseif(is_single(<?php global $post;
$categories = get_the_category();
foreach($categories as $category) {
$cat = $category[0]->cat_ID;
} ?> = **category#**)) echo('header**category#**');

[where **category#** would be an actual integer.

I’m not sure if that will work or not… I need a PHP reference book for this one! 😐

Echozone, what you’ve done is great! Can you please share the plugin you used or the code? Pretty please?? Thank you!!!
