Support,

Is there an option to add a Query Filter to display only related child posts?

My goal is to display 4-6 related posts at the end of the active/current post with the same child category.

Thanks,
Chuck

Hi Chuck

Can you clarify exactly what you are aiming for?

Where you say "related child posts" that sounds like you have set up parent-child post relationships and when viewing a child post you want to display siblings (i.e. other children of the same parent post).

But then you say "with the same child category", which sounds like something else.

Can you give a concrete example?

Nigel,

Apologies for the mixed language.

Here is the URL of an example post: enlace oculto

At the bottom of that post I am trying to display 4 Ashtray posts, 2x2 with a "more" button leading to ashtray archives. The site consists of a few parent categories and each parent has multiple children. I'm trying to create one view/template that will display posts related to the child category.

Thanks,
Chuck

Hi Chuck

This may not something you can readily do in Toolset without writing custom code. The problem is that when getting the categories of a post there is no distinction made about the position of the category in any hierarchy (https://developer.wordpress.org/reference/functions/get_the_category/).

I assume that for this example post it has both the cigar and the ashtray categories, yes?

You can create a View that you display on the same post which has a Query Filter to display posts with categories the same as the post where it is displayed (see screenshot).

But the current post with that example has the categories "cigar" and "ashtray". So the View will find posts that have categories "cigar" or "ashtray".

I assume you want it to only show other posts that have the "ashtray" category.

If you want that then you will need to code a custom solution.

If your related posts can be any other cigar-related post then the above will work for you.

Got it. Sounds like I need a custom solution. Do you have any insight as where to begin?

Thanks,

Hi Chuck

Sorry, I didn't manage to get to this today, I'll try and propose something for you tomorrow.

Nigel,

No worries. Your help is greatly appreciated!

Hi Chuck

I came up with the following code example for you.

You will need to edit the View ID.

Please note that providing custom code is outside of our support policy and this is intended to help you get started if the code needs modifying in any way.

The intended use is that you insert a View for related posts which has a Query Filter to display posts within the same category as the current post.

It then removes the top level categories from consideration.

So if you have an ashtray post which is categorised "cigar" and "ashtray" and you add a View as described above, this code will remove the parent "cigar" category from the matches, so it will find other posts with the ashtray category, but not lighter posts which also have the cigar category.

function skip_top_level_categories( $query_args, $view_settings, $view_id ){

	if ( 39 == $view_id ){

		global $post;
		$child_terms = array();

		$terms = wp_get_post_terms( $post->ID, "category" );

		foreach ($terms as $key => $term) {
			
			if ( 0 != $term->parent ) {

				$child_terms[] = $term->term_id;
			}
		}
		$query_args['tax_query'][0]['terms'] = $child_terms;

	}
	return $query_args;
}
add_filter( 'wpv_filer_query', 'skip_top_level_categories', 101, 3);

Nigel,

Thanks! I'll give this a try this evening.

Any updates on this thread: https://toolset.com/forums/topic/wrap-flexslider-in-custom-url/
I see it's marked closed. Not sure if I closed it by mistake or support did.

Hi Chuck

Let me know how you get on here and if you need more help or we can close this, thanks.

[Charles]

Nigel,

Per your instructions, I change this line:

    if ( 39 == $view_id ){

I changed 39 to 9094 (my view ID), but no changes occurred. Is there additional/different lines that need to be changed?

If this is out of scope please close the ticket.

Thanks,
Chuck

Hi Chuck

I looked at the code I suggested... and there is a tiny but crucial typo.

In the last line the name of the filter is "wpv_filter_query", it's missing a T.

[Charles]

That did the trick! Thank you for your help.

Best,
Chuck
