Here's a tiny shopping cart block for Ubercart that fits right in with the menu. Of course the standard block could be themed this way, but this is handy when the design calls for the full-sized block elsewhere in the layout.
/**
* Implementation of hook_block().
*/
function uc_microcart_block($op = 'list', $delta = 0, $edit = array()) {
switch ($op) {
case 'list':
$blocks[0] = array(
'info' => t('Micro-sized cart block for page header.'),
// This block cannot be cached, because anonymous
// sessions can have differing cart contents.
// To improve this, see drupal.org/project/uc_ajax_cart
'cache' => BLOCK_NO_CACHE,
);
return $blocks;
case 'view':
if ($item_count = uc_cart_get_total_qty()) {
$block = array();
$block['subject'] = '';
$block['content'] = theme('image',
drupal_get_path('module', 'uc_cart') .'/images/cart-full.png');
$block['content'] .= format_plural($item_count,
'My cart: 1 item', 'My cart: @count items');
$block['content'] = l($block['content'], 'cart', array('html' => TRUE));
return $block;
}
break;
}
