im sure that this is something simple and probably already posted but i can not find it.
1. i want to replace the "add to cart' text with a cart image.
in my custom node i have
<?php print $node->content['add_to_cart']["#value"] ?>
how do i replace this with an image?

2. is it possible when one product is already in cart to replace the 'add to cart' text with something like 'already in cart' link that will point to the cart view?

thank you very much

In your custom node you'd have to call hook_form_alter and have it look for that form's form_id. Then you would say:

<?php
$node->content['add_to_cart']['#value'] = ...
?>

followed by however you want to control it - form button or cart link.

2. You can do, I'm not sure the easiest way but I did it with my Content Template. Here's how I did it:

<?php
$cartitems = uc_cart_get_contents();

$allNids = array();

foreach($cartitems as $cartitem) {
      $allNids[]=$cartitem->nid; // Probably an easier way to do this.
    }

if(in_array($node->nid, $allNids)) {       

?>
<img src="/<?php echo path_to_theme(); ?>/images/in-your-cart.jpg" border="0">

<?php } else { ?>

<a href="/cart/add">[ADD TO CART]</a>

<?php } ?>

So it basically cycles through the nids in your cart, and if the nid of the product you're looking at is found in your cart's content nids array, then it displays the "already in your cart" image and disables the add to cart functionality (which I have done here using Cart Links).

I'm trying to figure out the same thing. I read about the hook_form_alter thingy, and I still cannot figure it out. All I want to do is replace the Add to cart with an image.

I really wish Ubercart was more theme-able, but so far I'm finding that some serious PHP and core hacks are necessary to get Ubercart to do what you want. Not very Drupal friendly!

fwiw, having images for buttons is a Drupal core issue. We know we have our faults for theming, but this isn't one of them. Eye-wink You can search d.o for several different examples on how to turn buttons into images, but overriding theme elements will always require some PHP somewhere.
