earlier posts link with wp_query

on this page i'm using the following code to pull in the 25 most recent posts from category 4.

<?php
$custom_query = new WP_Query( 'posts_per_page=25&cat=4' );
if ( $custom_query->have_posts() ) : while ( $custom_query->have_posts() ) : $custom_query->the_post(); ?>
<h3><?php the_title(); ?></h3>
<?php the_content(); ?>

<hr class="homenews" />

<?php endwhile; else : ?>
<h3>Sorry...</h3>
No posts were found.

<?php next_posts_link('&laquo; Older Entries') ?>

<?php endif; ?>

Code (markup):

but how do i add a link at the bottom of the page that says "click here for earlier posts", and leads to a page that lists the 25 items posted before that???

please advise. thanks in advance.

 

Try in custom page template.

1. Make a php file recentposts.php like below

<?php
/*
Template Name: 25 Recent posts
*/
?>
<?php get_header( ); ?>
Your custom code for 25 posts
<?php get_sidebar();?>
<?php get_footer(); ?>

2. Goto "Add New Page" in wp admin page. Then create new page with select the template name "25 Recent posts" in right side template selection dropdown.

3. Make a link manually in footer.php (for add a link in bottom of the site)
<a href="your newly created custom template link page">click here for earlier posts</a>
