Thanks Kobra. That's what I had to do. Just needed to know I wasn't missing something.
For those who are wondering, here is the CSS I am using and the lines of code I hacked.
In tpl_shopping_cart.php
Code:
if (($_SESSION['new_products_id_in_cart']) && ($_SESSION['new_products_id_in_cart'] == $products[$i]['id'])) {
$content .= '<div class="cartNewItem">';
} else {
$content .= '<div class="cartOldItem">';
}
$content .= zen_image(DIR_WS_IMAGES . $products[$i]['image'], $products[$i]['name'], IMAGE_SHOPPING_CART_WIDTH, IMAGE_SHOPPING_CART_HEIGHT) . '</div><div class="cartOldItemtext"> You have: <strong>' . $products[$i]['quantity'] . '</strong><br /><a href="' . zen_href_link(zen_get_info_page($products[$i]['id']), 'products_id=' . $products[$i]['id']) .'">'. $products[$i]['name'].'</a></div></li><br />' . "\n";
and the CSS
Code:
.cartNewItem {
float:left;
color: #000000;
margin-right: 3px;
position: relative; /*do not remove-fixes stupid IEbug*/
}
.cartOldItem {
vertical-align:middle;
float:left;
color: #000000;
margin-right: 3px;
position: relative; /*do not remove-fixes stupid IEbug*/
}
.cartOldItemtext {
vertical-align:middle;
font-size:.7em;
text-align:center;
color: #000000;
position: relative; /*do not remove-fixes stupid IEbug*/
}
Hope this helps others figure it out.
