Well the subject says it all - I'm trying to figure out how to add a link to my secondary links to 'View Cart'. Simple enough, except that I'd like to also show the number of products the user has added in brackets. For example 'View Cart (2)'

Anyone have any ideas?

Thanks!

Re: Re: View Cart (x) link showing number of products added?

In case this is of interest to anyone else, I found this piece of code which I used in my page template:

<?php
if (module_exists('uc_store')) {
  $items = uc_cart_get_contents();
  if (is_array($items)) {
    $hasItems = count($items);
  }
  else {
    $hasItems = 0;   
  }
}
?>

You should use this instead:

<?php
if (module_exists('uc_cart')) {
  $hasItems = 0;

  foreach (

uc_cart_get_contents() as $item) {
    $hasItems += $item->qty;
  }
}
?>

Exactly what I was looking for.

I just have 1 question. Where do I place this? My "view cart" button is a one of my secondary links which is basically a link name with a path.

If I add this to the text name of the link it just spits out the PHP not the cart #.

Re: Exactly what I was looking for.

You need to output this manually via your page.tpl.php (or similar) file, it's not possible to show the number of items in the cart using Drupal's menu builder.

Re: Re: Exactly what I was looking for.

You can (and should) do this in template.php rather than page.tpl.php

<?php
function THEMENAME_preprocess_page(&$vars)
{
  if (module_exists('uc_cart')) {
    $item_count= 0;

    foreach (
     

uc_cart_get_contents() as $item) {
      $item_count += $item->qty;
    }
  }
$vars['shopping_cart_link'] = l(format_plural($item_count, 'Shopping Cart: !count item', 'Shopping Cart: !count items', array('!count' => $item_count))
}
?>

You can now add the following to page.tpl.php:

<?php
print $shopping_cart_link;
?>

Perfect

Yeah, that's much cleaner. LIking it. I'll be using this for the site I'm working on this month.

EDIT:
The above code did not work for me in D6, UC2. The last line was flunking it out. I changed it as noted, and this works fine.

<?php
function framework_preprocess_page(&$vars) {
  $vars['tabs2'] = menu_secondary_local_tasks();

  if (

module_exists('uc_cart')) {
    $item_count= 0;
    foreach (
uc_cart_get_contents() as $item) {
      $item_count += $item->qty;
    }
  }
  if ($item_count==0) {
      $cart_contents = 'Cart Empty';
  }
  elseif ($item_count==1) {
        $cart_contents = '1 Item';
  }
  else {
      $cart_contents = ($item_count . ' Items');
  }  
$vars['shopping_cart_link'] = ('View Cart | ' . $cart_contents);
}
?>
