Here is my current code. I’ve resolved the issue of querying multiple post types but now I need to only get posts that have:
date_picker_value1 <= current_date <= date_picker_value2
$args = array (
'post_type' => array('friday','saturday','sunday','special'),
'meta_query' => array(
array(
'key' => 'publish_area',
'value' => 'left',
),
),
);
