Limit number of posts on a custom category template - breaking pagination

Question

The following code was mentioned from one of the commentors, however it is breaking the pagination. Any corrections please

 <?php 
    include(TEMPLATEPATH. '/includes/headline.php'); rewind_posts();
    if (have_posts()) 
    {
    echo '<div class="gridrow clear">';
    while (have_posts()) : the_post();
    global $post;
    $query_string;
    query_posts( $query_string .'&posts_per_page=5' );
    include(TEMPLATEPATH. '/includes/loop.php');
    $q = $wp_query->current_post;
    $maxq = tj_current_postnum();
    if($q < $maxq-1 && is_int(($q+1)/2)) echo '</div><div class="gridrow clear">';
    $postcount++;
    endwhile;
    echo '</div> <!--end .gridrow-->';
    } else { 
    include(TEMPLATEPATH. '/includes/not-found.php'); 
    } 
    if ( $wp_query->max_num_pages > 1 ) tj_pagenavi();?>

Answer 1

You need to tell Wordpress to get only 5 posts per page. The parameter to do this is posts_per_page. You should use query_posts() function before your have posts as in the following example.

<?php
   // your includes and stuff

   global $query_string;

   query_posts( $query_string . '&posts_per_page=5' );

   // now your have_posts
   if ( have_posts() ) {
       // list the posts
   } else {
       // not found msg here..
   }
?>

The code you have at the top of this page has a nested loop. Is that what you want?

The following code would normally go above the while loop for "the_post()"

$query_string;
query_posts( $query_string .'&posts_per_page=5' );

This may not be your issue, but I thought it may help.
