Pagination in categories with permalink set to postname

    Hi, I use this function to paginate posts within categories:

    add_filter( 'pre_get_posts', 'number_of_posts' );
function number_of_posts( $wp_query = '' ) {
	remove_filter( 'pre_get_posts', 'number_of_posts' );
	global $wp_query;
	$cat_obj = $wp_query->get_queried_object();
	$category_id = $cat_obj->term_id;
	if ( is_category(3) ) {
		$wp_query->query_vars['posts_per_page'] = 2;
	} elseif( is_category(1)) {
		$wp_query->query_vars['posts_per_page'] = 1;
	}

	return $wp_query;
}

    It works very fine if permalinks are set on default. But, if I use %postname%, it doesn’t work, and the number of displayed posts is the same of the global $posts_per_page set in “Settings / Reading”…

    Any idea?

    Thanks in advance!

    Ok… I tryed another way:

    add_filter( 'pre_get_posts', 'number_of_posts' );
function number_of_posts( $wp_query = '' ) {
	remove_filter( 'pre_get_posts', 'number_of_posts' );
	global $wp_query;
	global $wpdb;
	$cat_obj = $wp_query->get_queried_object();

		if ( $wp_query->is_category ) {
			if ( !($category_id = $wp_query->get('cat')) ) {
				$category    = $wp_query->get('category_name');
				$sqlstr  = "SELECT term_id FROM $wpdb->terms WHERE slug = '". $wpdb->escape($category) ."'";
				$category_id = (int) $wpdb->get_var($sqlstr);
				if ( $category_id==3 ) {
				echo "<script>alert (".$category_id.");</script>";
					$wp_query->query_vars['posts_per_page'] = 2;
				} elseif( $category_id==1) {
				echo "<script>alert (".$category_id.");</script>";
					$wp_query->query_vars['posts_per_page'] = 1;
				}
			}
			else  {
				$category_id = $cat_obj->term_id;
				if ( $category_id==3 ) {
					$wp_query->query_vars['posts_per_page'] = 2;
				} elseif( $category_id==1) {
					$wp_query->query_vars['posts_per_page'] = 1;
				}
			}
		}

	return $wp_query;
}

    But it still doesn’t work. The strange thing:
    the alert() function works and display the category id.

    Please help…

    Sorry… my fault! There was a conflict with another function… it works! But in the second way, not the first.

    Bye
