adding "order" as query arg to the homepage url you are redirected to the last posts page

[giuse]

I've tested it on many sites, with different plugins, no plugins, different themes, default WordPress themes. If you add ?order=something to the home page url you have a redirection to the last posts page.

Hi @giuse, welcome to WordPress Trac! Thanks for the report.

order is one of the ​reserved terms in WordPress. In WP_Query::parse_order()​, any value other than ASC is treated as DESC.

If the home page is set to display the latest posts, adding ?order=something doesn't seem to affect anything.

If a static home page is selected in Reading Settings, this parameter does indeed show the list of latest posts instead of the home page, but I don't necessarily see an issue with that.

I see a very big issue because WooCommerce uses this query argument in the download link for a digital product. If the customer clicks on that link instead to download the product sees the last posts.
In any case this is not normal and I think it can be easily avoided.

for people who have a shop with downloadable products who probably have my same problem, until WooCommerce or WordPress don’t find a clean solution, I suggest to use this dirty solution in functions.php:

if( !isset( $_GET[‘redirected’] ) && isset( $_GET[‘order’] ) && strpos( $_GET[‘order’],’wc_order’ ) === 0 ){
$_GET[‘redirected’] = true;
wp_redirect( add_query_arg( $_GET,get_permalink( get_option( ‘woocommerce_checkout_page_id’ ) ) ) );
exit;
}
