I am trying to sort custom posts using two meta fields ‘surname’ and ‘forenames’. The documentation is confusing me and I hope someone can help.
Here’s the code I have so far, which sorts the surname field:
function my_pre_get_posts( $query ) {
// do not modify queries in the admin
if( is_admin() ) {
return $query;
}
// only modify queries for ‘individuals’ post type
if( isset($query->query_vars[‘post_type’]) && $query->query_vars[‘post_type’] == ‘individuals’ ) {
$query->set(‘orderby’, ‘meta_value’);
$query->set(‘meta_key’, ‘surname’);
$query->set(‘order’, ‘ASC’);
}
// return
return $query;
}
add_action(‘pre_get_posts’, ‘my_pre_get_posts’);
How do I need to amend it?
Manny thanks

The only difference is that you set the meta_query and orderby values instead of what you’re doing.
Thanks John, though I don’t understand enough to know how to adapt my code. Is there a simple couple of lines I can add?
$meta_query = array(
'relation' => 'AND',
'date_clause' => array(
'key' => 'date_field_name',
'compare' => 'EXISTS'
),,
'time_clause' => array(
'key' => 'time_field_name',
'compare' => 'EXISTS'
),
);
$query->set('meta_query', $meta_query);
$orderby = array(
'date_clause' => 'ASC',
'time_clause' => 'ASC'
);
$query->set('orderby', $orderby);
Thank you John, I think I now understand what the query is doing.. However I’m getting an error which suggests the arrays are incorrect? See the error at the bottom of the image:
Thank you John, that works perfectly!
As a follow up, If I filter the posts by surname, the results are no longer in ascending order by forenames.. Does this mean I have to find a separate means of targeting the filtered results?
