[Support request] Using WPSP with Search and Filter Pro

Hello,

My question is a bit complex and it may not be possible to easily do what I want.

Today I use the plugin Search and filter Pro to display posts according to tags.

These posts are displayed with The Grid plugin (a plugin similar to WPSP).

For example here is a search on the “Rock” posts: https://hautlescours.fr/recherche/?_sft_pratiques=rock. Posts are filtered with Search and Filter Pro and displayed with The Grid.

To do that, Search and filter Pro uses a custom archive.php template which I modified to “call” The Grid. Search and filter Pro indicates that “Templates must use the The Loop and not a custom query”.

Here is the code of the custom archive.php template I use. The important part is the line The_Grid('Posts_archive', true); // where true is for template mode that makes it possible to display the filtered posts using The Grid plugin.

<?php
/**
 * The template for displaying Archive pages.
 *
 * @package GeneratePress
 */
if ( ! defined( 'ABSPATH' ) ) {
	exit; // Exit if accessed directly.
}
get_header(); ?>
	<div id="primary" <?php generate_do_element_classes( 'content' ); ?>>
		<main id="main" <?php generate_do_element_classes( 'main' ); ?>>
			<header class="page-header">
			<h1 class="page-title">Résultats de la recherche</h1>
			</header>		
			<?php	
			do_action( 'generate_before_main_content' );
			/*if ( generate_has_default_loop() )*/ {
			
			The_Grid('Posts_archive', true); // where true is for template mode	
		
}
			/**
			 * generate_after_main_content hook.
			 *
			 * @since 0.1
			 */
			do_action( 'generate_after_main_content' );			
			?>	
		</main>
	</div>
	<?php
	/**
	 * generate_after_primary_content_area hook.
	 *
	 * @since 2.0
	 */
	do_action( 'generate_after_primary_content_area' );
	generate_construct_sidebars();
	get_footer();

I tried to do something similar with WPSP using the line if ( function_exists( 'wpsp_display' ) ) wpsp_display( 78685 ); instead of The_Grid('Posts_archive', true); but unfortunately it displays all the posts and not only the filtered posts (posts with the tag “Rock” in my example hereabove).

Bottom line: I would like to use WPSP with Search Filter Pro given that WPSP doesn’t have a filter/search function

What are your views on that? I understand this question is difficult and relates to a third-party plugin.
Best,
