Label/Title as link

In any case you can do this by overriding the templates.

You will find this code in dc_ajax_add_cart.module

function template_preprocess_dc_ajax_shopping_cart(&$variables) {
...
    foreach ($line_item_list as $line_item) {
      if (property_exists($line_item, 'commerce_product')) {
        $product = commerce_product_load($line_item->commerce_product[LANGUAGE_NONE][0]['product_id']);

        if (variable_get('dc_ajax_add_cart_update_quantity', 0) == 1) {
          $updateable_quantity = drupal_get_form('dc_ajax_add_cart_update_quantity_' . $line_item->line_item_id, $line_item);
          $quantity = drupal_render($updateable_quantity);
        }
        else {
          $quantity = intval($line_item->quantity);
        }

        $row[] = array(
          array('data' => $quantity, 'class' => array('quantity')),
          array('data' => $product->title, 'class' => array('name')),
          array('data' => $product_prices[$product->product_id], 'class' => array('price')),
          array(
            'data' => l(variable_get(DC_AJAX_ADD_CART_REMOVE_CART, 'link') == 'link' ? t('Remove from cart') : $image_remove_cart,
            'remove-product/nojs/' . $line_item->line_item_id,
            array(
              'attributes' => array(
                'class' => array('use-ajax'),
              ), 'html' => TRUE)), 'class' => array('remove-from-cart')),
        );
      }
    }
...
}

array('data' => $product->title, 'class' => array('name')), this is the code that generates product title. You can use this code in your custom theme template preprocess, and override it there, and then use thise code to generate the cart markup:

    $variables['products_list_html'] = theme('table', array(
      'header' => $header,
      'rows' => $row,
      'attributes' => array(
        'class' => array('ajax-shopping-cart-table'),
      ),
      'sticky' => FALSE,
    ));

I am leaving it opened because I would like to add this in the module itself. Patches are welcome.

I used to query the database:

<?php
function template_preprocess_dc_ajax_shopping_cart(&$variables) {
...
foreach ($line_item_list as $line_item) {
...
$id = $product->product_id;
$id_node = db_select('field_data_field_product', 'n')
				  ->fields('n', array('entity_id'))
				  ->condition('n.field_product_product_id', $id)
				  ->execute()
				  ->fetchField();
		
$node_url = url('node/' . $id_node, array('absolute' => TRUE));

$row[] = array(
...
array('data' => '<a href="'.$node_url.'">'.$product->title.'</a>', 'class' => array('name')),
...
);
}

...
}
?>
