Make Wordpress not Show Posts of Subcategory
In some cases you may wish to display ONLY the posts of a category and not posts of its child categories on a Wordpress blog.
Lets say you had a parent category of "Weather" with sub-categories "America" and "United Kingdom". When a user clicks on the weather category, Wordpress will automatically display posts from the Weather category AS WELL AS the posts of America and United Kingdom.
If this is not the behaviour you are after, there is a template tag trick that you can use in your theme to show posts of the current category ONLY.
If you have an archive.php or category.php open that, otherwise open index.php. Don't forget to back them up just in case things go wrong!
Find the line similar to:
<?php while (have_posts()) : the_post(); ?>
Which is the start of "The Loop" and add after it on the next line:
<? if ((is_category()) && in_category($wp_query->get_queried_object_id())) { ?>
This line checks if we are viewing a category, and that the post being processed is a member of the category being viewed. If it is then we will show the post.
$wp_query->get_queried_object_id() returns an integer ID of the category being viewed.
in_cagegory() tests if the current post in the loop is a member of the specified category, in this case we pass it the current category.
Next find the line:
<?php endwhile; ?>
Which is the end of the loop, and add a line BEFORE it containing:
<?php } ?>
This small modification will stop posts of child categories from showing when a parent category is selected. Of course you will need some posts in Weather otherwise you will have a blank page. You can also use the information on the Wordpress Codex template tags to create static pages for each category if you wish.
If you only wish to stop sub category posts from showing on one particular parent category you can specify the required category in the is_category() method. Simply insert the numerical id of the parent category in the brackets, e.g. is_category(10) will stop sub category posts from showing only if we are viewing the category with ID of 10. All other categories will retain their default setting.
