Okay. I took a look at your site. You seem to using categories to show wedding, portraits, events and blog. I’m going to assume that you do not want the other posts of these categories to appear in your blog. So, the use of category would be appropriate.
Here’s how I would do it.
1. Duplicate the page.php template in your theme file and rename it category-(insert your category id).php. Based on your site, I determined that your blog category id is 4. Thus, category-4.php.
The reason why we are not duplicating the archive.php in your theme is because the blog formatting is not already there. By using page.php we retain the the main page and right side-bar layout.
Note: Check out this page in wordpress codex, for the category template.
2. Open category-4.php in a editor of your choice (I use Editra). Replace everything within the div id “content” with the following code. Then test your site to see if it works correctly. If it does work do the css styling. In the next step, I’ll show you the code to add numbered pagination.
<!-- Start the Loop. -->
<?php if ( have_posts() ) : while ( have_posts() ) : the_post(); ?>
<!-- The following tests if the current post is in category 4. -->
<!-- If it is, the div box is given the CSS class "post-cat-four". -->
<!-- Otherwise, the div box will be given the CSS class "post". -->
<? php if ( in_category('4') ) { ?>
<div class="post-cat-four"> <?php } else { ?>
<div class="post"> <?php } ?>
<!-- Display the Title as a link to the Post's permalink. -->
<h2><a href="https://wordpress.stackexchange.com/questions/58333/<?php the_permalink() ?>" rel="bookmark" title="Permanent
Link to <?php the_title_attribute(); ?>"><?php the_title(); ?></a></h2>
<!-- Display the date (November 16th, 2009 format) and a link to other posts
by this posts author. -->
<small><?php the_time('F jS, Y') ?> by <?php the_author_posts_link() ?></small>
<!-- Display the Post's Content in a div box. -->
<div class="entry"> <?php the_content(); ?> </div>
<!-- Display a comma separated list of the Post's Categories. -->
<p class="postmetadata">Posted in <?php the_category(', '); ?></p>
</div> <!-- closes the first div box -->
<!-- Stop The Loop (but note the "else:" - see next line). --> <?php endwhile; else: ?>
<!-- The very first "if" tested to see if there were any Posts to -->
<!-- display. This "else" part tells what do if there weren't any. -->
<p>Sorry, no posts matched your criteria.</p>
<!-- REALLY stop The Loop. --> <?php endif; ?>
Note: The code above is from wordpress codex, which I have already adjusted to your category ‘blog’.
3. Add pagination after your loop with this pagination tutorial by WP tut. I have extracted the code for easy reference.
<?php global $wp_query;
$total_pages = $wp_query->max_num_pages;
if ($total_pages > 1){
$current_page = max(1, get_query_var('paged'));
echo paginate_links(array(
'base' => get_pagenum_link(1) . '%_%',
'format' => '/page/%#%',
'current' => $current_page,
'total' => $total_pages,
));
} ?>
You can style the pagination links with the css code provided on the tutorial.
Please note that I did not test out the code. I hope this helps.
