wordpress add link for next post

I need to add links in wordpress on single post page for post before and for post after the current post from that category.
I guess i need to create some loop and include category there, but i don*t know how to make it post only 1 link for the next post because the next postid doesn*t have to be from the same category, and on the other side i need only 1 link for next post not all posts from that category.

 

next post:

<?php next_post_link('%link', 'Next post in category', TRUE); ?>

PHP:

previous post:

<?php previous_post_link('%link', 'Previous post in category', TRUE); ?>

PHP:

Maybe you can use anchor text link at the bottom of your post.

 

the best way is the way mentioned above by ansi

 

Yes...of course. Both are right.
