Comment filtrer le type de post personnalisé par taxonomie?

voici mon code essayant de le faire

<div class="row">
<div class="col-lg-3 col-md-12">
    
    <div class="card">
        <div class="card-body">
            
        <form action="<?php the_permalink() ?>" method="GET">
            <?php
            $terms = get_terms([
              'taxonomy' => 'topics',
              'hide_empty' => false
            ]);
            foreach ( $terms as $term ) : ?>
                <label>
                    <input
                        type="checkbox"
                        name="topics[]"
                        value="<?php echo $term->slug; ?>"
                        <?php checked(
                        (isset($_GET['topics']) && in_array($term->slug, $_GET['topics']))
                        ) ?>
                    />

                    <?php echo $term->name; ?>
                </label>
            <?php 
            endforeach; ?>
            <button type="submit">Apply</button>
        </form>

        </div>
    </div>
    
</div><!--end of col1 col-lg-3 col-md-12 -->
<div class="col-lg-9 col-md-12">
    
    <div class="row">
    <?php
    $courses = new WP_Query(
        array(

            'tax_query' => array(
                array(

                    'field'    => 'slug',
                    'terms'    => $term->slug,
                    'operator' => 'IN'
                )
            ) // This is the amount of posts per page you want to show
        )

    <?php 
    endwhile;
    rewind_posts();
    wp_reset_postdata();
    ?> 
    </div>
    
</div><!--end of col2 col-lg-9 col-md-12 -->
</div>

mais quand je rafraîchis la page, il faut essayer de charger et quand je supprimai la fonction rewind_posts, il charge la page, mais les filtres ne fonctionnent pas, j'ai regardé de nombreuses vidéos essayant de le résoudre mais qu'aucun code de réussite expliquant deux colonnes une fois les filtres et la deuxième colonne ayant les postes

Je crois que vous pouvez ajouter ce qui suit aux fonctions du thème.php & Visit /courses/?topics=foo,bar Pour obtenir les résultats que vous recherchez:

<?php

/**
 * Custom search-query with taxonomy filter
 */
function wpse373353_search_query( $wp_query ) {

    // exit early if this isn't that main loop on the front-end of the site
    if ( ! $wp_query->is_main_query() || is_admin() ) {
        return;
    }

    if ( $wp_query->get( 'post_type' ) === 'courses' ) {

        if ( ! empty( $_GET['topics'] ) ) {
            $topics = $_GET['topics'];
            foreach ( $topics as $key => $val ) {
                $topic_terms[ $key ] = sanitize_key( $val );
            }
        }

        if ( ! empty( $topic_terms ) {
            
            if ( ! $tax_query = $wp_query->get( 'tax_query' ) ) {
                $tax_query = [
                    // change to OR instead of default AND here if desired
                    // 'relation' => 'OR',
                ];
            }

            // add the topics tax-query
            if ( ! empty( $topic_terms ) ) {
                $tax_query[] = [
                    'taxonomy' => 'topics',
                    'field'    => 'slug',
                    'terms'    => $topic_terms,
                ];
            }

            // save the modified wp_query
            $wp_query->set( 'tax_query', $tax_query );

        }
        
    }
}
// hook into the pre_get_posts action
add_action( 'pre_get_posts', 'wpse373353_search_query' );
