Is there a way I can list all posts in a specific custom post type and arrange them by the custom taxonomy term attached to them?
For example;
Taxonmy Term #1
Post Type
Post Type
Post Type
Taxonomy Term #2
Post Type
Post Type
Any help would be most appreciated.
Thanks.

Method 1
Try this
$custom_terms = get_terms('custom_taxonomy');
foreach($custom_terms as $custom_term) {
wp_reset_query();
$args = array('post_type' => 'custom_post_type',
'tax_query' => array(
array(
'taxonomy' => 'custom_taxonomy',
'field' => 'slug',
'terms' => $custom_term->slug,
),
),
);
$loop = new WP_Query($args);
if($loop->have_posts()) {
echo '<h2>'.$custom_term->name.'</h2>';
while($loop->have_posts()) : $loop->the_post();
echo '<a href="'.get_permalink().'" rel="nofollow noreferrer noopener" rel="nofollow noreferrer noopener" rel="nofollow noreferrer noopener">'.get_the_title().'</a><br>';
endwhile;
}
}
We get all the terms of a taxonomy, loop through them, and fire off a title link to each post that belongs to that term. If you need to reorder the taxonomy terms, you can do so with a plugin pretty easily. Reorder Taxonomy, I believe. But pay attention that this plugin adds(!) another column to your table on activation and does not remove it upon deactivation!
Method 2
Not a particularly elegant solution but you can create multiple queries each for the specific terms and then output them. Hopefully someone can come up with a nicer way of automatically pulling the terms to modify the output/sorting. But this would get you going.
<?php
//First Query for Posts matching term1
$args = array(
'tax_query' => array(
array(
'taxonomy' => 'taxonomy_1',
'field' => 'slug',
'terms' => array( 'term1' )
),
),
'post_type' => 'my-post-type'
);
$query = new WP_Query( $args );
if ( have_posts() ) {
$term = $query->queried_object;
echo 'All posts found in ' . $term->name;
while ( have_posts() ) : the_post();
//Output what you want
the_title();
the_content();
endwhile;
}
//RESET YOUR QUERY VARS
wp_reset_query();
//Second Query for term2
$args = array(
'tax_query' => array(
array(
'taxonomy' => 'taxonomy_1',
'field' => 'slug',
'terms' => array( 'term2' )
),
),
'post_type' => 'my-post-type'
);
$query = new WP_Query( $args );
if ( have_posts() ) {
$term = $query->queried_object;
echo 'All posts found in ' . $term->name;
while ( have_posts() ) : the_post();
//Output what you want
the_title();
the_content();
endwhile;
}
Method 3
Nice one! GhostOne’s solution was what I had been looking for.
In my situation the custom post type was ‘minining_accidents’ and custom taxonomies associated with this was ‘accident-types’ which had multiple terms under it. My idea was to create a custom widget to show list of posts under terms in this custom taxonomies. In my trial run it got what I wanted. Rest was spruce up. Here is my code:
function fn_get_list_of_mining_accident_types()
{
$custom_taxonomy='accident-types';
$custom_terms = get_terms($custom_taxonomy);
$str_return='<ul>';
foreach($custom_terms as $custom_term)
{
wp_reset_query();
$args = array(
'post_type' => 'minining_accidents',
'tax_query' => array(
array(
'taxonomy' => $custom_taxonomy,
'field' => 'slug',
'terms' => $custom_term->slug,
),
),
);
$loop = new WP_Query($args);
$term_name=$custom_term->name;
$term_slug=$custom_term->slug;
$term_link=get_term_link($term_slug, $custom_taxonomy);
$str_return.='<li><a href="'.$term_link.'" rel="nofollow noreferrer noopener">'.$term_name.'</a>';
if($loop->have_posts())
{
$str_return.='<ol>';
while($loop->have_posts()) : $loop->the_post();
$str_return.='<li><a href="'.get_permalink().'" rel="nofollow noreferrer noopener" rel="nofollow noreferrer noopener" rel="nofollow noreferrer noopener">'.get_the_title().'</a></li> ';
endwhile;
$str_return.='</ol>';
}
$str_return.='</li>';
}
$str_return.='</ul>';
return $str_return;
}
Yes! There always is an option to further improve the code.
Method 4
This is long solution i tried before coming to this thread. Hope this may help someone to understand better.
<?php
// Get list of all taxonomy terms -- In simple categories title
$args = array(
'taxonomy' => 'project_category',
'orderby' => 'name',
'order' => 'ASC'
);
$cats = get_categories($args);
// For every Terms of custom taxonomy get their posts by term_id
foreach($cats as $cat) {
?>
<a href="<?php echo get_category_link( $cat->term_id ) ?>" rel="nofollow noreferrer noopener">
<?php echo $cat->name; ?> <br>
<?php // echo $cat->term_id; ?> <br>
</a>
<?php
// Query Arguments
$args = array(
'post_type' => 'portfolio', // the post type
'tax_query' => array(
array(
'taxonomy' => 'project_category', // the custom vocabulary
'field' => 'term_id', // term_id, slug or name (Define by what you want to search the below term)
'terms' => $cat->term_id, // provide the term slugs
),
),
);
// The query
$the_query = new WP_Query( $args );
// The Loop
if ( $the_query->have_posts() ) {
echo '<h2> List of posts tagged with this tag </h2>';
echo '<ul>';
$html_list_items = '';
while ( $the_query->have_posts() ) {
$the_query->the_post();
$html_list_items .= '<li>';
$html_list_items .= '<a href="' . get_permalink() . '" rel="nofollow noreferrer noopener">';
$html_list_items .= get_the_title();
$html_list_items .= '</a>';
$html_list_items .= '</li>';
}
echo $html_list_items;
echo '</ul>';
} else {
// no posts found
}
wp_reset_postdata(); // reset global $post;
?>
<?php } ?>
Method 5
To show a list of custom posts from a custom taxonomy
$args = array(
'tax_query' => array(
array(
'taxonomy' => 'your-custom-taxonomy',
'field' => 'slug',
'terms' => array( 'your-term' )
),
),
'post_type' => 'your-post-type'
);
$loop = new WP_Query($args);
if($loop->have_posts()) {
$term = $wp_query->queried_object;
while($loop->have_posts()) : $loop->the_post();
//Output what you want
echo '<li><a href="'.get_permalink().'" rel="nofollow noreferrer noopener" rel="nofollow noreferrer noopener" rel="nofollow noreferrer noopener">'.get_the_title().'</a></li>';
endwhile;
}
