Hi, i had an question. I made an shortcode which displays me locations. I use a meta_value ( ACF field ) to filter. But when i on a page of these locations, this one location should not be displayed. It should be excluded. I tryed the WP argument ‘post__not_in’ => array( $post->ID ) but it dont works.

Here is my code:

function messe_feld( $atts ) {

	$veranstalter = get_field('messe_namen_detail');

    // Defaults
    extract( shortcode_atts( array (
        'kategorie' => '',
        'veranstalter' => $veranstalter
    ), $atts ) );
 
    // Parameter
    $options = array(
        'post_type' => 'messen',
        'messe_kategorie' => $kategorie,
        'meta_value' => $veranstalter
    );

// query
$the_query = new WP_Query( $options );

if( $the_query->have_posts() ): 

        $return .= '<div class="messe-liste">';
        while( $the_query->have_posts() ) : $the_query->the_post();  

            $return .= '<div class="messe-item">';
                $return .= '<div class="messe-header-jail">';
                    $return .= '<img class="messe-bild" src="/wp-content/themes/wpcasa/img/messe-bild.jpg" alt="Messe Header" />';
                    $return .= '<img class="messe-logo" src="'.get_field('messe_logo').'" alt="Messe Logo" />';
                $return .= '</div>';
            $return .= '<div class="messe-datum">'.get_field('messe_datum_beginn').' - '.get_field('messe_datum_ende').'</div>';
            $return .= '<div class="messe-title">'.get_field('messe_name').'</div>';
            $return .= '<div class="messe-beschreibung">'.get_field('messe_beschreibung').'</div><span class="messe-weiter">Mehr erfahren</span>';
            $return .= '<a class="messe-details-link" href="'.get_field('messe_details_link').'"></a>';
            $return .= '</div>';

        endwhile;
        $return .= '</div>';
        endif;
        wp_reset_postdata();
        return $return;

}
add_shortcode( 'messe-feld', 'messe_feld' );

I hope you understand me, sorry for my bad english.

$post->ID does not have a value inside of your function unless you declare the global

function messe_feld( $atts ) {
  global $post;
    // ......
