Ok insert this code into your functions.php. You have to replace the variable $your_ajax_page_slug with the name of your page that you want the redirect to cart functionality to be disabled. Ensure that you have 'Enable AJAX add to cart buttons on archives" checked in settings.
add_filter( 'woocommerce_get_script_data', 'modify_woocommerce_get_script_data', 20, 2 );
function modify_woocommerce_get_script_data ( $params, $handle ) {
global $wp;
$page_slug = '';
$your_ajax_page_slug = 'your-page-slug';
$current_url = home_url( $wp->request );
// Break the URL by the delimiter
$url_pieces = explode('/', $current_url);
// Get the page slug
if( is_array( $url_pieces ) )
$page_slug = end( $url_pieces );
if( $handle == 'wc-add-to-cart' && $page_slug == $your_ajax_page_slug ) {
$params['cart_redirect_after_add'] = false;
}
return $params;
}
