I would like to turn a php function on and off, I've placed this code on my index.php
<?php
function default_sort_ascend($t) {
$q = $t->query_vars;
if ( empty($q['order']) || ((strtoupper($q['order']) != 'DESC') && (strtoupper($q['order']) != 'ASC')) )
$q['order'] = 'ASC';
$t->query_vars = $q;
}
add_action('pre_get_posts', 'default_sort_ascend');
?>
How to create a button to switch back and forth from 'DESC' to 'ASC'?
The code above is great because it affects not only the home page but also the archives, etc...
Thank you
