Let's 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 the 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 (start of the loop):
<?php while (have_posts()) : the_post(); ?>
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 need to 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.
Excellent! I tried a lot of plugins for view posts only from parent category without sub, but when one post is in parent and child category, they weren't working. Thank you very much
hey dear
the information u provide is not enough to solve my problems..
pls explaine in detail...
YES! After 3 hours searching this nails it. (will have to be sure it doesn't paginate though!
BTW for anyone who gets a fail: In the top code, you must change the & & to just one &
get_queried_object_id())) { ?>
2feedme: thank you a lot!!
Nice solution, I really thank you for your tutorial!!!
there is an issue when used with wp-pagenavi....
it counts all the posts that return from the have_posts() function
so it shows a blank page (or more) in pagenavi.
i found this and its working.

Perfect! only one addition, how to display one of the categories just one? thank you so much.
Finally.. I got it.. Thank you so much dude.. I was looking for this for about two weeks.
Regards
I was looking for this for over one month. Thank you. it worked for me.
Perfect!
Worked perfect for me. I found the code in archive.php -> themes folder.
Yep, didn&squot;t work for me either...
causes a fatal error in category.php in V 2.51 Any ideas??
thanks
I tried this fix but then the first page of every main category was blank. The "next" page would show entries that were inside that main category, but for some reason the first page still showed up without any posts on it. ???
Works fine on all the sub categories but the main category is blank, any ideas?
