WordPress Pagination on Page - wordpress

Question

I have the following code on a WordPress page. It basically just grabs 3 posts and displays them as well as the page content itself up top. What I want to add is pagination so that a user can flick through all the posts, how do I get this working with custom loops like this?
<?PHP
get_header();
/* Template Name: News */
?>
<div style="padding: 0 20px;">
<div class="box clearfix side" style="margin:10px 0;">
<div style="float:left;width:628px;">
<?php if (have_posts()) : while (have_posts()) : the_post(); ?>
<div class="content" id="post-<?php the_ID(); ?>">
<h2><?php the_title(); ?><?php edit_post_link('Edit', ' <small>[', ']</small>'); ?></h2>
<?php the_content('<p>Read the rest of this page »</p>'); ?>
<?php wp_link_pages(array('before' => '<p>Pages: ', 'after' => '</p>', 'next_or_number' => 'number')); ?>
<hr />
</div>
<?php endwhile; endif; ?>
<hr />
<?php $blog_query = new WP_Query('posts_per_page=3'); while ($blog_query->have_posts()) : $blog_query->the_post(); ?>
<div class="content" id="post-<?php the_ID(); ?>">
<h4><?php the_title(); ?></h4>
<?php the_excerpt(); ?>
</div>
<?php endwhile; ?>
<?php if ($blog_query->have_posts()) : ?>
<?php if(function_exists('wp_pagenavi'))
{
wp_pagenavi();
}
?>
<?php else: ?>
<h2>oooops!!!</h2>
<?php endif; ?>
</div>
</div>
</div>
<?PHP
get_footer();
?>

Answer 1

Are you sure you're not re-inventing the wheel a little here? Why not set the number of posts to display in the admin, then use WP's native paging for the blog?

Answer 2

Turns out you have to do something like this:
<?php $temp = $wp_query; $wp_query= null; ?>
<?php $wp_query = new WP_Query(array('posts_per_page' => 3, 'paged' => $paged)); while ($wp_query->have_posts()) : $wp_query->the_post(); ?>
<div class="content" id="post-<?php the_ID(); ?>">
<h4><?php the_title(); ?></h4>
<?php the_excerpt(); ?>
</div>
<?php endwhile; ?>
<?php if(function_exists('wp_pagenavi'))
{
wp_pagenavi();
}
?>
<?php $wp_query = null; $wp_query = $temp; ?>
