Limited number of products displayed on portfolio page

Limited number of products displayed on portfolio page

On the portfolio page I want to a limited number of products. I have 300
products and that's too much to be all on one page.
I put this code for limited number of products (10 products per page)
'posts_per_page' => 10
And I put this code for insert page switching (in this case 30 page)
<!-- Pagination -->
<?php if(function_exists('pagination')){ pagination(); }else{
paginate_links(); } ?>
<!-- Pagination End -->
And in fact both codes work. Number of shown products is limited to 10
products. At the bottom of the page I got the option to switch to one of
the 30 pages.
But whatever number page I click, I always opened the first 10 the
products of.
