So, I have a couple custom fields using ACF. On them I have a field called cd\_location (group -> repeater -> select).

I've made a page template (based on my custom working archive) that should return ALL the courses that contain the location Y (GET / xxx.com/?loc=YYY) but it's not working at all and I don't know why. Can someone advise please?

Based on [Dynamic $\_GET parameters](https://www.advancedcustomfields.com/resources/query-posts-custom-fields/).

**My top php code:**

```
global $post;
global $_GET;
$heading = get_field( 'heading', $post->ID );
$course_dates = get_field('course_dates', $post->ID);

```

**Then I have the loop:**

```
<?php
                if ( have_posts() ) : 
                    $counter = 0;
                    while ( have_posts() ) : the_post(); ?>
                        <div class="one_half<?php echo ( ++$counter == 2 ) ? ' last_column' : ''; ?>">
                            <div class="break-link">
                                <?php
                                get_portfolio_item_thumbnail( $post->ID, '5', '528', '328', true );
                                ?>
                            </div>
                            <h4 class="cont-subtitles"><a href="<?php the_permalink(); ?>"><?php the_title(); ?></a></h4>
                            <p class="excerpt"><?php echo excerpt(15); ?></p>
                        </div><!-- end one_half -->

                        <?php if ( $counter == 2 ) : ?>
                            <div class='clear'> </div>
                        <?php $counter = 0; 
                        endif;
                    endwhile;
                endif; ?>

```

**This on functions.php:**

```
add_action( 'pre_get_posts', function( $query ) {
        if ( isset( $query->query_vars[ 'post_type' ] ) && $query->query_vars[ 'post_type' ] == 'e-kursus' && isset( $_GET[ 'loc' ] ) ) {
            $query->set( 'meta_key', 'cd_location' );
            $query->set( 'meta_value', sanitize_text_field( $_GET[ 'loc' ] ) );
        }
        return $query;
    } );

```

It's returning a dummy post with the name of the page with no fields from ACF
