Loop through custom taxonomies and display posts
-

Question
While I've been able to get this working for normal WP categories I've been unable to get it working for custom taxonomies.
I'd like to loop through each custom taxonomy (categories in my case) and produce a number of posts for each.
An example of the output would be:
Category 1
post from category one
post from category one
read more category one
Category 2
post from category two
post from category two
read more category two
Of course it would repeat through any available taxonomy for the custom post type.
Solution
I thought I would provide another answer as the above one is a little hacky, also I added another layer that gets all taxonomies for a post_type.
$post_type = 'post';
// Get all the taxonomies for this post type
$taxonomies = get_object_taxonomies( (object) array( 'post_type' => $post_type ) );
foreach( $taxonomies as $taxonomy ) :
// Gets every "category" (term) in this taxonomy to get the respective posts
$terms = get_terms( $taxonomy );
foreach( $terms as $term ) :
$posts = new WP_Query( "taxonomy=$taxonomy&term=$term->slug&posts_per_page=2" );
if( $posts->have_posts() ): while( $posts->have_posts() ) : $posts->the_post();
//Do you general query loop here
endwhile; endif;
endforeach;
endforeach;
It would be recommended to add each post found to a $post__not_in
array, so you could pass that to the WP_Query
to prevent duplicate posts coming through.
OTHER TIPS
Are you looking for this ?
<?php query_posts(array('post_type' => 'post type name', 'Taxonomy slug' => $term->slug ) ); ?>
<?php if ( have_posts() ) : while ( have_posts() ) : the_post(); ?>
<?php endwhile; else: ?>
<p><?php _e('Sorry, no posts matched your criteria.'); ?></p>
<?php endif; ?>
How to create Custom Taxonomy loop
Hope it will help
Copy and paste this function in your functions.php
if ( ! function_exists( 'display_all_products_from_all_categories' ) ) {
function display_all_products_from_all_categories() {
// Get all the categories for Custom Post Type Product
$args = array(
'post_type' => 'product',
'orderby' => 'id',
'order' => 'ASC'
);
$categories = get_categories( $args );
foreach ($categories as $category) {
?>
<div class="<?php echo $category->slug; ?>">
<!-- Get the category title -->
<h3 class="title"><?php echo $category->name; ?></h3>
<!-- Get the category description -->
<div class="description">
<p><?php echo category_description( get_category_by_slug($category->slug)->term_id ); ?></p>
</div>
<ul class="mhc-product-grid">
<?php
// Get all the products of each specific category
$product_args = array(
'post_type' => 'product',
'orderby' => 'id',
'order' => 'ASC',
'post_status' => 'publish',
'category_name' => $category->slug //passing the slug of the current category
);
$product_list = new WP_Query ( $product_args );
?>
<?php while ( $product_list -> have_posts() ) : $product_list -> the_post(); ?>
<li class="product <?php the_field( 'product_flavor' ); ?>">
<a href="<?php the_permalink(); ?>" class="product-link">
<!-- if the post has an image, show it -->
<?php if( has_post_thumbnail() ) : ?>
<?php the_post_thumbnail( 'full', array( 'class' => 'img', 'alt' => get_the_title() ) ); ?>
<?php endif; ?>
<!-- custom fields: product_flavor, product_description ... -->
<h3 class="title <?php the_field( 'product_flavor' ); ?>"><?php the_title(); ?></h3>
<p class="description"><?php the_field( 'product_description' ); ?></p>
</a>
</li>
<?php endwhile; wp_reset_query(); ?>
</ul>
</div>
<?php
}
}
}
Then call it from anywhere in your template with:
display_all_products_from_all_categories();
Please check this example; create a own loop for your taxonomie. You can also use this in a foreach-loop to use all categories. Or you must create an own sql-query.
<?php
$taxonomies = get_the_term_list($post->ID, 'YOUR_TAXONOMIE', '', '', '');
$taxonomies = explode('>', $taxonomies);
$taxonomies = $taxonomies[1];
$myq = new WP_Query('your_taxonomie = '.$taxonomies);
if ($myq->have_posts()) : while ($myq->have_posts()) : $myq->the_post(); // the loop ?>
<?php the_title();?>
<?php the_content();?>
<?php endwhile; else:?>
<?php endif;?>
