Update my custom theme cart to show correct product link
As default the links within cart should reflect the original shop where they pushed to the cart. In some cases a custom theme is not using the recommended WooCommerce template implementation which conclude to wrong url. Fortunate this is a small update, explained in the following lines.
Many themes use something like this to output the cart:
global $woocommerce;
$carts = array_reverse( $woocommerce->cart->get_cart() );
foreach ( $carts as $cart_item_key => $values ) : ?>
<?php $_product = $values['data'];
if ( $_product->exists() && $values['quantity'] > 0 ): ?>
<div class="product">
... more code ...
</div>
<!--/product -->
<?php endif; ?>
<?php endforeach; ?>
This need a bit of update to include the switch_to_blog() and restore_current_blog() so add the 2 new lines:
global $woocommerce;
$carts = array_reverse( $woocommerce->cart->get_cart() );
foreach ( $carts as $cart_item_key => $values ) : ?>
<?php do_action( 'woocommerce/cart_loop/start', $values ); ?>
<?php $_product = $values['data'];
if ( $_product->exists() && $values['quantity'] > 0 ): ?>
<div class="product">
... more code ...
</div>
<!--/product -->
<?php endif; ?>
<?php do_action( 'woocommerce/cart_loop/end', $values ); ?>
<?php endforeach; ?>
At this point the products within the cart, pushed on other shops will use the correct links back to original shop.
