Also tried this:
<?php if (is_page( 'testpagina' ) ) {
// args
$args = array(
'numberposts' => -1,
'post_type' => 'any',
'meta_query' => array(
'relation' => 'OR',
array(
'key' => 'niveau_jaren',
'value' => '%Jaar 1%',
'compare' => 'LIKE'
),
array(
'key' => 'niveau_jaren',
'value' => '%Jaar 3%',
'compare' => 'LIKE'
)
)
);
// get results
$the_query = new WP_Query( $args );
This should mean it gets the posts with value ‘Jaar 1’ or ‘Jaar 3’, right? I don’t get anything..
