Hi basically I made a loop page but i just want to query posts from my custom posts type called “videos” then i have a custom post taxonomy along with “videos” called “topics”

<?php
       
       $customPost_type = 'videos';
       $taxonomyValue = get_field('loop_select_video');
       $taxonomyVideoNum = get_field('loop_number_of_videos');
       if($taxonomyValue){ 
       $args=array(
         'taxonomy' => $taxonomyValue,
         'post_type' => $customPost_type,
         'posts_per_page'=> $taxonomyVideoNum, // Number of related posts to display
         'order'=>'DESC' //query desc posts
        );
        
        $my_query = new wp_query( $args );
        while( $my_query->have_posts() ) {
        $my_query->the_post();
        ?>
       
      
       <article class="art-article art-video">       
      
        <?php if(get_field('video_code')) { ?>
         <div class="art-article-video">
          <?php echo do_shortcode('
          
          ['. get_field('video_type') .' id="'. get_field('video_code') . '"]
          
          ');?>
         </div>
        <?php } ?>

        
        <div class="art-article-desc alpha">
         <a href="#" title="<?php the_title(); ?>">
          <h2><?php the_title(); ?></h2>
         </a>
         <?php if(get_field('video_code')) { ?>
         <p><?php echo get_field('video_description');?></p>
         <?php } ?>
        </div>
       </article>
       
       
       
       <?php
       
       }
       
       wp_reset_query();
       }else{ //if no tag is selected
       echo("no Tag is selected in the Taxonomy Dropdown menu");
       }
       ?>
       
       <!-- LOOP -->

      
      </div>

In my page editor, there is a select box contains contents from topics (means categories of videos)..

that when i tick one of them, it should loop according from what i selected.. but in my case it doesnt .. by the way it has a hierarchy.

– Topic
– type a
– type b
– type c
– type d

if i want to select the type a , the loop should only show posts from type a . same with type b ,type c , and type d.. then If i select the parent “Topic” it should show all.. My was if i select the children they doesnt work but the parent works.. please help me.

– Topic
* Type a
* Type b
* Type c
* Type d

Hi @slash_1968

Just to clarify. Your question is how to get your WP_Query behaving correctly?

Lets first start by debugging the code. Perhaps you could print out the $args array. What does it look like? Does it look correct?

Then, print out the $my_query object. You will see a section of the object contains the actual SQL which is run. Does this look correct?

Please research up on the WP_Query object before posting back if you don’t understand some of the above.

Thanks

Hi @elliot,

sorry for the confusion.. i was trying to loop a post by terms under taxonomy.

Post type: Video
taxonomy: Topics
terms under topics:

– Videos
* Video type 1 (sub)
* Video type 1 (sub)
* Video type 1 (sub)
* Video type 1 (sub)
