[Resolved] Display posts using values from dynamically populated select custom fields

Tell us what you are trying to do?
I have a custom post type (locations) that uses a content template. Inside the content template, I want to create a view that lists 3 nearby locations. The locations are the same post type, kind of like related posts but author defined.

I'm using 3 select custom fields (Nearby Communities One, Nearby Communities Two, Nearby Communities Three) in the locations post type dynamically populated from the locations post list using this code:

add_filter( 'wpt_field_options', 'func_dynamic_populate', 10, 3);

function func_dynamic_populate( $options, $title, $type ){
switch( $title ){
case 'Nearby Communities One':
case 'Nearby Communities Two':
case 'Nearby Communities Three':

$options = array();
$args = array(
'post_type' => 'location',
'posts_per_page' => -1,
'post_status' => 'publish');

$posts_array = get_posts( $args );

foreach ($posts_array as $post) {
$options[] = array(
'#value' => $post->ID,
'#title' => $post->post_title,
);
}
break;
}
return $options;

This code works to populate the select fields so the author can choose their 3 nearby location posts.

I've created a view to display these posts in the content template, but I can't work out what the query filter in the view should look like. No matter what I do the view just shows the latest 3 posts rather than the ones defined in the select fields.

Is there any documentation that you are following?
Nope, can't find anything

Is there a similar example that we can see?
No

What is the link to your site?
hidden link <<example page, Nearby Communities section

Hi,

Thank you for contacting us and I'd be happy to assist.

To limit the view's results, to only the location post IDs, coming from those 3 custom fields, you can use the 'wpv_filter_query' filter:
https://toolset.com/documentation/programmer-reference/views-filters/#wpv_filter_query

For example:

add_filter( 'wpv_filter_query', 'custom_filter_custom_field_posts', 1000 , 3 );
function custom_filter_custom_field_posts( $query_args, $view_settings ) {
	if ( ( isset($view_settings['view_id']) && $view_settings['view_id'] == 7547) ) {

		$post_array = array();
		$post_array[] = types_render_field( 'nearby-communities-one', array( 'output' => 'raw' ) );
		$post_array[] = types_render_field( 'nearby-communities-two', array( 'output' => 'raw' ) );
		$post_array[] = types_render_field( 'nearby-communities-three', array( 'output' => 'raw' ) );

		$query_args['post__in'] = $post_array;
		
	}
	return $query_args;
}

Note: The '7547' is the ID of the view that is being used on that example page, for the nearby location. Please make sure that the custom field slugs 'nearby-communities-one', 'nearby-communities-two', & 'nearby-communities-three' are used as set on your website.

The above code snippet can be included through either Toolset's custom code feature ( ref: https://toolset.com/documentation/adding-custom-code/using-toolset-to-add-custom-code/ ) or through the active theme's "functions.php" file.

I hope this helps and please let me know if you need further assistance.

regards,
Waqar
