Thank you, getting closer. I had a parse error with the code you provided and changed it slightly to that:

<?php
$args = array(
  'taxonomy' => 'reisezeit'
);
$terms = get_terms($args);
$selected_terms = get_field('saison', false, false); // get only term IDs
if ($selected_terms) {
  foreach ($terms as $term) {
    if (in_array($term->term_id, $selected_terms)) {
      echo 'Found';
    } 
    else {
      echo 'NotFound';
    }
  }
}
?>

This returns me: FoundFoundNotFoundNotFoundFoundFoundFoundFoundFoundFoundFoundFoundFoundFoundNotFound
which is a little bit strange since it’s 15 matches/non matches, but my taxonomy can have 16 values (12 months + 4 seasons). Querying like so:

<?php
$args = array(
  'taxonomy' => 'reisezeit'
);
$terms = get_terms($args);
$selected_terms = get_field('saison', false, false);
print_r ($selected_terms);
?>

Gives me the ID’s of the selected terms:
Array ( [0] => 105 [1] => 95 [2] => 96 [3] => 97 [4] => 106 [5] => 98 [6] => 99 [7] => 100 [8] => 101 [9] => 107 [10] => 102 [11] => 103 )
which should be fine.

But how can I query in this result for a specific term ID? (as an end result I want to have 12 divs for all 12 months, but those months that are not selected greyed out // the selected ones marked with a color). So I need to do 12 in_array queries.

Thank you, Ralf
