Hi,
There were some code errors so i corrected.Please open to edit cart.php at /joyn/woocommerce/cart/.
Find this code:-
<div class="cart-collaterals">
<?php do_action('woocommerce_cart_collaterals'); ?>
</div>
Change to :-
<div class="cart-collaterals">
<?php
global $product, $woocommerce, $woocommerce_loop;
$upsells = $product->get_upsells();
if ( sizeof( $upsells ) == 0 ) return;
$meta_query = $woocommerce->query->get_meta_query();
$args = array(
'post_type' => 'product',
'ignore_sticky_posts' => 1,
'no_found_rows' => 1,
'posts_per_page' => $posts_per_page,
'orderby' => $orderby,
'post__in' => $upsells,
'post__not_in' => array( $product->id ),
'meta_query' => $meta_query
);
$products = new WP_Query( $args );
//$woocommerce_loop['columns'] = $columns;
$woocommerce_loop['columns'] = 4;
if ( $products->have_posts() ) : ?>
<div class="upsells products">
<h4 class="lined-heading"><span><?php _e( 'You may also like…', 'swiftframework' ) ?></span></h4>
<?php woocommerce_product_loop_start(); ?>
<?php while ( $products->have_posts() ) : $products->the_post(); ?>
<?php woocommerce_get_template_part( 'content', 'product' ); ?>
<?php endwhile; // end of the loop. ?>
<?php woocommerce_product_loop_end(); ?>
</div>
<?php endif;
wp_reset_postdata();
?>
</div>
Thanks
