Pagination removing space in query

I’m wondering the same thing. We have a URL structure like this…

https://mydomain.com/some-category/?subject=Some+Subject

I’m trying to get pagination properly working. I urlencode() the space and get the +, but it doesn’t matter if I use a space or a + …Wordpress always tries to do this…

https://mydomain.com/some-category/page/2/?subject=SomeSubject

…instead of this…

https://mydomain.com/some-category/page/2/?subject=Some+Subject

WordPress is removing the space/+ for some reason. We haven’t figured out why just yet. Any help is greatly appreciated.

The problem is caused by the canonical redirect checked on using a theme. If you place
remove_action('template_redirect','redirect_canonical');
in the functions.php file belonging to your template, the problem is fixed.

If you want more information, see
this related issue.

Is there another fix. Cause remove_action(‘template_redirect’,’redirect_canonical’); just breaks everything.

<?php
global $wp_query, $wp_rewrite;
$wp_query->query_vars['paged'] > 1 ? $current = $wp_query->query_vars['paged'] : $current = 1;

$pagination = array(
	'base' => @add_query_arg('paged','%#%'),
	'format' => '',
	'total' => $wp_query->max_num_pages,
	'current' => $current,
	'show_all' => true,
	'type' => 'plain'
	);

if( $wp_rewrite->using_permalinks() )
	$pagination['base'] = get_bloginfo('url') . '/page/%#%/';

$cq = $_GET['s'];
	$sq = str_replace(" ", "+", $cq);

if( !empty($wp_query->query_vars['s']) )
	$pagination['add_args'] = array( 's' => $sq);

echo paginate_links( $pagination );
?>
