Block template override / X for Remove Product

Hey there,

I am looking to replace the "Remove Product" text and table row with a more simplistic X icon or link that removes the product instead. I will try to post my progress on the goal, but for now I just wanted to share some quick information on how to override the block and do a custom template without modifying the module.

The first thing you can do is copy uc_ajax_cart_block_content.tpl.php to your theme from uc_ajax_cart/templates/uc_ajax_cart_block_content.tpl.php -- this will allow you to customize the template quite a bit. However, for my goal with replacing Remove Product I need to also override some of the information provided to that block template. I did this by copying the uc_ajax_cart_preprocess_uc_ajax_cart_block_content function from uc_ajax_cart.theme.inc to my template.php while replacing uc_ajax_cart with mytheme like mytheme_preprocess_uc_ajax_cart_block_content

Note that for some reason this method requires a couple changes in order for it to work properly. One example is needing to change $item->module to $item['item']->module

function mytheme_preprocess_uc_ajax_cart_block_content(&$vars) {
  $content = $vars['items'];
  $items = array();

  $context = array(
    'revision' => 'themed',
    'type' => 'price',
  );

  $total = 0;
  $total_items = 0;
  foreach ($content as $item) {
    $display_item = module_invoke($item['item']->module, 'cart_display', $item['item']);
    if (!empty($display_item)) { 
          $attributes = $item->data['attributes'];
          $total += $display_item['#total'];
          $total_items += $display_item['qty']['#default_value'];
            $items[] = array(
              'nid'      => $display_item['nid']['#value'],
              'qty'      => t('@qty×', array('@qty' => $display_item['qty']['#default_value'])),
              'title'    => $display_item['title']['#value'],
              'descr'    => isset($display_item['description']['#value']) ? $display_item['description']['#value'] : FALSE,
              'link'     => url('node/' . $item['item']->nid),
              'item'     => $item,
              'image'    => uc_product_get_picture($display_item['nid']['#value'], 'cart'),
              'node'     => node_load($item['item']->nid),
              'total'    => uc_price($display_item['#total'], array(
                'revision' => 'themed-original',
                'type' => 'amount',
                )),
              'remove_link' => l(t('Remove ppproduct'),
                                  UC_AJAX_CART_REMOVE_CALLBACK,
                                  array(
                                  'attributes' => array(
                                                    'onclick' => "ajaxCartBlockUIRemove(this.href); return false;",
                                                    'class'    => 'remove-cart-link remove-cart-link-' . $display_item['nid']['#value'],
                                                  ),
                                  'query' => array(
                                    'nid' => $display_item['nid']['#value'],
                                    'destination' => $_GET['q'],
                                    'data' => base64_encode($display_item['data']['#value']),
                                    'action' => 'remove',
                                  ),
                                )
                              ),
            );
    }
  }
  $vars['total'] = uc_price($total, $context);
  $vars['items'] = $items;
  $vars['item_count'] = $total_items;
  $vars['cart_links'] = theme('uc_ajax_cart_cart_links');
  $vars['items_text'] = format_plural( $total_items , '<span class="num-items">@count</span> Item', '<span class="num-items">@count</span> Items');

}

I will go ahead and continue working on my present goal and will share the outcome as a patch in case other people are interested in the same thing or if it is to be considered for a commit.
