Sometimes, WordPress developers may need custom loops that cannot be generated using standard loops (such as category, author, index, date, archive, taxonomy, etc.). One of them is "Posts I commented on” >". In Q&A sites it means "questions I answered", so many developers may need it. Building on this tutorial, we can create another custom loop. Let's create this section.

step 1

Go to your theme folder and create a myanswers.php file and copy and paste the following code into it:

<?php /* Template Name: myanswers */ ?>
<?php
get_header(); ?>
<?php
get_template_part( 'loop', 'myanswers' );	 
?>
<?php get_sidebar(); ?>
<?php get_footer(); ?>

Copy after login

We just created a template file named myanswers. It will be used to display our custom loop.

Step 2

Stay in your theme folder and create a second file called loop-myanswers.php. and paste the following code into the file:

<?php
if($wp_query->query_vars['paged']==0){$wp_query->query_vars['paged']=1;}
$querystr = "
    SELECT $wpdb->posts.* 
    FROM $wpdb->posts  inner join $wpdb->comments on $wpdb->posts.ID=$wpdb->comments.comment_post_ID 
    WHERE $wpdb->posts.post_status='publish' and $wpdb->comments.user_id=".wp_get_current_user()->ID."
    GROUP BY $wpdb->posts.ID
    ORDER BY $wpdb->posts.post_date DESC  ";

$lim_per_page=" limit ".($wp_query->query_vars["posts_per_page"]*($wp_query->query_vars['paged']-1)).",".$wp_query->query_vars["posts_per_page"];

$query_for_count = $wpdb->get_results($querystr, OBJECT);
$wp_query->max_num_pages=ceil($wpdb->num_rows/$wp_query->query_vars["posts_per_page"]);
$querystr=$querystr.$lim_per_page;
$pageposts = $wpdb->get_results($querystr, OBJECT);
 ?>

<?php if ($pageposts): ?>
 <?php global $post; 
 ?>
 
 <?php foreach ($pageposts as $post): ?>
 <?php setup_postdata($post); ?>
 
<?php
/// THIS PART IS LOOP FROM TWENTYTEN, YOU CAN CHANGE IT HOWEVER YOU WANT BEGIN
?>
<div id="post-<?php the_ID(); ?>" <?php post_class(); ?>>
<h2 class="entry-title"><a href="<?php the_permalink(); ?>" title="<?php printf( esc_attr__( 'Permalink to %s', 'twentyten' ), 
the_title_attribute( 'echo=0' ) ); ?>" rel="bookmark"><?php the_title(); ?></a></h2>

			<div class="entry-meta">
				<?php twentyten_posted_on(); ?>
			</div><!-- .entry-meta -->

	<?php if ( is_archive() || is_search() ) : // Only display excerpts for archives and search. ?>
			<div class="entry-summary">
				<?php the_excerpt(); ?>
			</div><!-- .entry-summary -->
	<?php else : ?>
			<div class="entry-content">
				<?php the_content( __( 'Continue reading <span class="meta-nav">→</span>', 'twentyten' ) ); ?>
				<?php wp_link_pages( array( 'before' => '<div class="page-link">' . __( 'Pages:', 'twentyten' ), 'after' => '</div>' ) ); ?>
			</div><!-- .entry-content -->
	<?php endif; ?>

			<div class="entry-utility">
				<?php if ( count( get_the_category() ) ) : ?>
					<span class="cat-links">
						<?php printf( __( '<span class="%1$s">Posted in</span> %2$s', 'twentyten' ), 'entry-utility-prep entry-utility-prep-cat-links', get_the_category_list( ', ' ) ); ?>
					</span>
					<span class="meta-sep">|</span>
				<?php endif; ?>
				<?php
					$tags_list = get_the_tag_list( '', ', ' );
					if ( $tags_list ):
				?>
					<span class="tag-links">
						<?php printf( __( '<span class="%1$s">Tagged</span> %2$s', 'twentyten' ), 'entry-utility-prep entry-utility-prep-tag-links', $tags_list ); ?>
					</span>
					<span class="meta-sep">|</span>
				<?php endif; ?>
				<span class="comments-link"><?php comments_popup_link( __( 'Leave a comment', 'twentyten' ), __( '1 Comment', 'twentyten' ), __( '% Comments', 'twentyten' ) ); ?></span>
				<?php edit_post_link( __( 'Edit', 'twentyten' ), '<span class="meta-sep">|</span> <span class="edit-link">', '</span>' ); ?>
			</div><!-- .entry-utility -->
		</div><!-- #post-## -->

 <?php endforeach; 
/// THIS PART IS LOOP FROM TWENTYTEN, YOU CAN CHANGE IT HOWEVER YOU WANT  END
?>
 <?php else : ?>
    <h2 class="center">Not Found</h2>
    <p class="center">Sorry, but you are looking for something that isn't here.</p>
    <?php include (TEMPLATEPATH . "/search.php"); ?>
 <?php endif; ?>
 
 <?php
echo  $wp_query->max_num_pages;
 if (  $wp_query->max_num_pages > 1 ) : ?>
				<div id="nav-below" class="navigation">
					<div class="nav-previous"><?php next_posts_link( __( '<span class="meta-nav">←</span> Previous', 'twentyten' ) ); ?></div>
					<div class="nav-next"><?php previous_posts_link( __( 'Next<span class="meta-nav">→</span>', 'twentyten' ) ); ?></div>
				</div><!-- #nav-below -->
<?php endif; ?>

Copy after login

This file is used to generate our custom loop in the template file.

Step 3

Open your theme's theme functions file (functions.php) and add this function and filter to the file:

add_filter('query_vars', 'parameter_queryvars' );
function parameter_queryvars( $qvars )
{
/* Plugin Name: Parameter
Plugin URI: https://webopius.com/
Description: A plugin to allow parameters to be passed in the URL and recognized by WordPress
Author: Adam Boyse
Version: 1.0
Author URI: http://www.webopius.com/
*/
$qvars[] = 'paged';
return $qvars;
}

Copy after login

This pair of functions and filters is used to obtain the page ID required to build pagination in a permalink structured site.

Step 4

Finally, go to your dashboard, create new page from Pages -> Add new page and name it "myanswers", by default its slug will be myanswers. Select a template for this page before publishing. In the template widget, you will see a combo box containing the myanswers option. Select it.

Create a personalized loop for My Comment Posts

After selecting the myanswers option, click the Publish button.

Finish!

You can now use yoursite.com/myanswers url as the page that displays the "Posts you commented on" loop. Of course, not just you, every logged in user can see theirs.
