Different number of posts (WordPress)

Question

We have selected to show 5 posts per page in admin panel.

And we want to show 10 posts per page in specific category (for example, "projects" width id=2).

How would we do it?

Answer 1

Change the normal loop to a query post. Like

if ( is_category(2) ){

//The Query
query_posts('posts_per_page=5');

//The Loop
if ( have_posts() ) : while ( have_posts() ) : the_post();
   the_content();
endwhile; else:
   echo'Nothing here...';
endif;

//Reset Query
wp_reset_query();

}
