I am using the below code to sort posts based on my meta key sub_seminars_0_start_date
. The code works fine as it gets all the posts from portfolio post_type
and then sorts them based on my meta key. However when I through a taxonomy query it displays nothing, a blank page with header and footer.
<?php
$args = array(
'post_type' => 'dt_portfolio',
'post_status' => 'publish',
'tax_query' => array(
array(
'taxonomy' => 'dt_portfolio_category',
'field' => 'slug',
'terms' => '',
),
),
'meta_key' => 'sub_seminars_0_start_date',
'orderby' => 'meta_value_num',
'order' => 'ASC',
);
$query = new WP_Query( $args ); ?>
How can I sort my posts that are in the taxonomy archive page ?
function change_order_for_events( $query ) {
//only show future events and events in the last 24hours
$yesterday = date('Ymd');
if ( $query->is_main_query() && (is_tax('dt_portfolio_category') || is_post_type_archive('dt_portfolio')) ) {
$query->set( 'meta_key', 'sub_seminars_0_start_date' );
$query->set( 'orderby', 'meta_value_num' );
$query->set( 'order', 'ASC' );
//Get events after 24 hours ago
$query->set( 'meta_value', $yesterday );
$query->set( 'meta_compare', '>' );
//Get events before now
//$query->set( 'meta_value', current_time('timestamp') );
//$query->set( 'meta_compare', '<' );
}
}
add_action( 'pre_get_posts', 'change_order_for_events' );
this code in function.php will sort your posts based on a specific meta key value.
sub_seminars_0_start_date
I have created a custom taxonomy Seminar Venues
but the above code won’t work for that even after adjustin the parameters.
