This – from the ACF docs – is the kind of thing I’m trying to do, but this code isn’t working:
$posts = get_posts(array(
'meta_query' => array(
array(
'key' => 'field_name', // name of custom field
'value' => '"red"', // matches exaclty "red", not just red. This prevents a match for "acquired"
'compare' => 'LIKE'
)
)
));
if( $posts )
{
//...
}
