WP_Query – Order by multiple custom fields

By Bridget Wessel | February 26, 2016

The Code

$args = array(

    'post_status' => 'publish'                  
    'post_type'     => 'board',
    'meta_query' => array(
        'last_name' => array(
            'key'     => 'last_name'
        ),
        'first_name' => array(
             'key' => 'first_name'
        ),
     ),
     'orderby'   => array( 'last_name' => 'ASC', 'first_name' => 'ASC' ),
     'nopaging' => true
 );

$query = new WP_Query( $args );

if ( $query->have_posts() ) :
    while ( $query->have_posts() ) : $query->the_post();

$args = array(

'post_status' => 'publish'

'post_type' => 'board',

'meta_query' => array(

'last_name' => array(

'key' => 'last_name'

'first_name' => array(

'key' => 'first_name'

'orderby' => array( 'last_name' => 'ASC', 'first_name' => 'ASC' ),

'nopaging' => true

);

$query = new WP_Query( $args );

if ( $query->have_posts() ) :

while ( $query->have_posts() ) : $query->the_post();

Always call

wp_reset_postdata()

1	wp_reset_postdata()

afterwards to reset the global $post value. Otherwise, any attempt to retrieve data from the page will return null.
