Stopped showing older posts when clicking on next page

According to Scribu,
“Say you have something like this:
query_posts(‘cat=8’);
or like this:
query_posts( array( ‘cat’ => 8 ) );
You just need to pass along the ‘paged’ query var from the main query:
query_posts( array( ‘cat’ => 8, ‘paged’ => get_query_var(‘paged’) ) );
If that doesn’t work, you can also try passing the ‘page’ query var:
query_posts( array( ‘cat’ => 8, ‘paged’ => get_query_var(‘page’) ) );

I actually have this:

<?php
                                $paged = ( get_query_var('paged') ) ? get_query_var('paged') : 1;

				$wp_query = new WP_Query (array(
				   'paged' => $paged,
				   'posts_per_page' => 3,
				   'order' => 'DESC',
				   'cat' => '-1077, -1076',
				   'post__not_in' => get_option( 'sticky_posts' )
				));

                                if ($wp_query->have_posts()) : while($wp_query->have_posts()) : $wp_query->the_post();?>

I’m really unsure as to where to put Scribu’s code? Any suggestions? I’m not a PHP coder i’m afraid, so it’s a bit intimidating!

Hi,

Looking at the documentation, I think the following code would work:

<?php

// Get paged or page if available
$paged = ( get_query_var('paged') ) ? get_query_var('paged') : get_query_var( 'page' );

$my_query = new WP_Query (array(
	'paged' => $paged,
	'posts_per_page' => 3,
	'order' => 'DESC',
	'cat' => '-1077, -1076',
	'post__not_in' => get_option( 'sticky_posts' )
));

if ( $my_query->have_posts() ) :
	while( $my_query->have_posts() ) : $my_query->the_post();
		// Do other loop stuff here
	endwhile;
endif;

// Now display pagenavi
if ( function_exists( 'wp_pagenavi' ) ) :
wp_pagenavi( array(
	// Pass our own query variable
	'query' => $my_query,
) );
else :
// Bring in default next/previous page links
endif;

// Avoid side effects
wp_reset_query();
