Hey Helmet,
thank you for your answer. I allready found a solution with the help of a developer.
It seems quite similar to yours.
Just for anyone who’s interested:
`
<?php
$locations = get_sub_field(‘orte_eingrenzen’);
$locationsSelected = array();
foreach( $orte as $ort ):
$locationsSelected[] = $ort->slug;
endforeach;
$loop = new WP_Query( array( ‘post_type’ => ‘kurse’, ‘posts_per_page’ => 99, ‘meta_key’ => ‘datum’, ‘orderby’ => ‘meta_value’, ‘order’ => ‘ASC’,
‘tax_query’ => array(
array(
‘taxonomy’ => ‘loacations’,
‘field’ => ‘slug’,
‘terms’ => $locationsSelected
)
)
) );
?>
