PHP/Wordpress: list posts per sub-category

In the below code there's a loop that features all products under a given category:


            query_posts($query_string . '&posts_per_page=15&paged=' . $paged);
            if (have_posts()) :
            while ( have_posts() ) : the_post();
                $price =  get_post_meta(get_the_ID(), 'inception_price', true);


            <div class="omc-product-listing">
                <a href="<?php the_permalink();?>">

                        if(has_post_thumbnail()) {
                        the_post_thumbnail('product', array('class' => 'omc-product-frame'));  
                        } else {

                    <img src="<?php echo get_template_directory_uri() ;?>/images/no-image.png" width="170" height="170" class="omc-product-frame" alt="no photo" />

                    <?php } ?>


                <span class="omc-listing-header"><a href="<?php the_permalink();?>"><?php the_title();?></a></span>

                <span class="omc-listing-price"><?php echo($price);?></span>

                <span class="omc-listing-more"><a href="<?php the_permalink();?>">&raquo;</a></span>

            </div><!-- /omc-product-listing -->

        <?php endwhile;  ?>

        <br class="clear" /> 

        <div class="product-pagination">

            <?php  kriesi_pagination(); ?>    


        <br class="clear" /> 

        <?php endif; wp_reset_query(); ?>

In this loop, I'd like to pull out every product for a given category (that's what the code does now), but display then "per subcategory", like this:

For category publications:


  • Book 33
  • Book 32
  • Book 1
  • ...

Mobile Apps:

  • App 12
  • App 76
  • ...


I think the code above needs a foreach loop, like below, but I don't know how to implement it in this case.

            // get all the categories from the database
            $cats = get_categories();

                // loop through the categories
                foreach ($cats as $cat) {
                    // setup the categories ID
                    $cat_id= $cat->term_id;
                    // Make a header for the categories
                    echo "<h2>".$cat->name."</h2>";
                    // create a custom wordpress query
                    // start the wordpress loop!
                    if (have_posts()) : while (have_posts()) : the_post(); ?>

                        <?php // create our link now that the post is setup ?>
                        <a href="<?php the_permalink();?>"><?php the_title(); ?></a>
                        <?php echo '<hr/>'; ?>

                    <?php endwhile; endif; // done our wordpress loop. Will start again for each category ?>
                <?php } // done the foreach statement ?>


I've taken this request to It just got resolved by Abdessamad Idrissi. the answer is too long to copy it here, so I'm posting the discussion link and the code link here, in case someone has the same need.

You could try the following:

$cats = get_categories();

foreach ($cats as $cat) :

// setup the categories ID
 $cat_id= $cat->term_id;
// Make a header for the categories
echo "<h2>".$cat->name."</h2>";

$args = array( 'cat' => $cat_id, 'posts_per_page' => 100 );

$posts = get_posts($args);

if($posts) :

foreach($posts as $post) : setup_postdata($post); ?>

<a href="<?php the_permalink();?>"><?php the_title(); ?></a>

<?php endforeach; // foreach($posts)

endif; // if($posts)

endforeach; // foreach($cats)

Not tested this but it should put you in the right direction!
