single.php wordpress中的类别描述

Question

any ideas.

this works fine in category.php <?php echo category_description(the_category_id()); ?>

but it does not work in single.php, just the category id shows up not the description.

any ideas, how to get this done?

thanks in advance

Answer 1

the_category_id() 

has been deprecated. This should work instead.

$category = get_the_category();
echo category_description($category[0]->cat_ID);
