Wordpress Query by Category using Post Slug

Question

I am trying to query some posts by the category slug (and parent post category slug)

I can get the slug using

<?php echo $post->post_name; ?>

or

<?php $post_data = get_post($post->post_parent);
$parent_slug = $post_data->post_name;
echo $parent_slug; ?>

I would like to insert that into the query below:

<?php $query = new WP_Query(array(
'post_type' => 'offers',
'category_name' => 'PAGE-SLUG-event'
)); ?>

So effectively I am trying to do this, which doesn't obviously work.

 <?php $query = new WP_Query(array(
 'post_type' => 'offers',
 'category_name' => '<?php echo $post->post_name; ?>-event'
 )); ?>

Answer 1

function namefunctions(){ $args = array( 'post_type' => 'CPT', 'posts_per_page' => -1, ); $recetax = new wp_query($args); while ( $recetax->have_posts()): $recetax->the_post(); ?>

/* your content of ctp*/

<?php endwhile; wp_reset_query();  

}
