Hello I am new to wordpress and I am creating a custom template. I am sorry if this is simple and has been asked before. I have 8 posts in a page and I have set the page to display a maximum of 4 posts on this page. So my question is how can I create something like arrows which can change from "pageName/1" to "pageName/2" which will display the other 4 posts also known as older posts.
The term you are looking for is Pagination.
Placing this code inside the loop should work:
<div class="nav-previous alignleft"><?php next_posts_link( 'Older posts' ); ?></div> <div class="nav-next alignright"><?php previous_posts_link( 'Newer posts' ); ?></div>
