Got it! need to foreach the $filter array 🙁
if($programCat){
// meta filter
$metaFilter = array('relation' => 'OR');
foreach ($programCat as $program){
$filter = array(
'key' => 'zorgverlener_programmas',
'value' => '"'.$program.'"',
'compare' => 'LIKE'
);
array_push($metaFilter, $filter);
}
}
is there a nicer way to do this?
