I’m using a custom loop to display my events on a page, I get it fine ordering by the event start date using the below:
$args = array(
'post_type' => 'event',
'order' => 'ASC',
'orderby' => 'meta_value',
'meta_key' => '_event_start_date');
$loop = new WP_Query( $args );
But the meta_key option only allows one value. How to use two values (_event_start_date and _event_start_time)?
From WP_Query documentation, use meta_query and fill up with an array of meta key/values:
$args = array(
'post_type' => 'product',
'meta_query' => array(
array(
'key' => 'color',
'value' => 'blue',
'compare' => 'NOT LIKE'
),
array(
'key' => 'price',
'value' => array( 20, 100 ),
'type' => 'numeric',
'compare' => 'BETWEEN'
)
)
);
$query = new WP_Query( $args );
