How To: Nested Loopers w/ Parent/Child CPT relationships

[simeoned]

This will be so much easier to show than to tell but, here’s the basic idea:

1. I have A CPT called “Locations” which allow for parent/child relationships.
2. I want to create all 50 States and nest certain Regions under them.
3. I want to create a looper which will go and get the titles of each State and place them in columns (easy)
4. Then in a list under each State name, another looper to go a get only those Regions which are a children of that State.

So, North Carolina has a column returned by the first looper which outputs “North Carolina”. South Carolina has a second column which out puts "“South Carolina”. AND under each one is listed the children of each.

North Carolina
-Charlotte
-Monroe
-Asheville

South Carolina
-Greenville
-Columbia

How can this be setup to work like I am describing?
Here’s a short video fro clarity:

Thank you!

Hi @simeoned,

Thanks for reaching out.
To check the setting you have in your Looper Provider, can you please share the following details in the secure note to examine it further, including:

– WordPress Site URL & Login URL
– WordPress Admin username/password

To create a secure note, click the key icon underneath any of your posts.

Thanks

The Secure note has been created for you to look around. A few details I wanted to bring up.

1. Please have a look here at the sandbox I setup for you: https://gestaltcreations.com/fia/sandbox/
   a. The first section has a manually build example of what I am trying to do exactly.
   b. The second section has what I am trying to do dynamically but don’t have working yet.

2. In that second section, the “First Looper” is the one using a Custom Provider Type referencing the following hook in my functions.php file

    // For Themeco Sandbox
    add_filter('cs_looper_custom_locations', function($result, $args) {
    return get_posts( 
    array(
    	'post_type' => 'locations',
    	'numberposts' => -1,
    	'orderby' => 'title',
    	'order' => 'ASC',
    	'post_parent' => 0
    )
   );
   }, 10, 2);  
   

Note that I’ve limited the query to output just the parent posts.

3. Finally the third section is where I echoed out the performed objects so we could see the data and how to potentially use it for the purposes I am describing. The custom shortcode I used for this is build in functions.php as well and looks like this:

   // For Themeco Sandbox
   function sandbox_output( $atts ){
   
   $posts = get_posts( 
    array(
    	'post_type' => 'locations',
    	'numberposts' => -1,
    	'orderby' => 'title',
    	'order' => 'ASC',
    	// 'post_parent' => 0
    )
   );
   
   echo '<pre>';
   print_r($posts);
   echo '</pre>';
   }
   add_shortcode( 'get_posts', 'sandbox_output' );
   

Not the query here is NOT limited to the parents of the post type only. This is so we can see everything in question and the relationship between them.

Hi @simeoned,

Unfortunately, the browser level restriction credentials are not provided and the current credentials do not work with it. I would suggest you check and provide the credentials for it.

Thanks

Secure note added… sorry about that.

Hello @simeoned,

It seems that the parent post id is not passed into the Nested Looper. This can be achieved by customization and that is beyond the scope of theme support. I would suggest you hire a developer who can assist you to do the customization or you can avail of our newly launched service called One, where the customization questions are answered.

Thanks for understanding
