Hiding CCK field in Product View

Hi,

I posted a topic a few minutes ago, but have just removed it, as it was inaccurate.

In case anyone has read the topic, this is the actual situation and what I want to achieve.

I have found the solution to what I need to do, but when trying to implement it, it isn't working out. I've been going at this problem for over 12 hours straight.

I have created 2 CCK fields with wholesale prices. I wish to hide these prices when users are not logged in by using a custom module. I also wish to display a helper text with the prices, when users are logged in.

Here is the code I have tried:

<?php
  function uc_product_nodeapi(&$node, $op, $arg3, $arg4){
    global $user;
    switch ($op){
      case 'view':
$node->field_wholesale_price_single[0]['view'] =  $node->field_wholesale_price_single[0]['view'] && $user->uid;

$node->content['field_wholesale_price_multiple']['#weight'] = $node->content['field_wholesale_price_multiple']['#weight'] && $user->uid;
break;
    }
  }
?>

I can enable this module, but it is not having any effect.

I have also customised my product display page with the file: node-product-tpl.php, with the code:

<div id="product_title"><h2><?php print $title ?></h2></div>
<div id="product_image"><?php print $node->picture ?> <?php print $node->content['image']['#value'] ?></div>

<div id="product_code">Code: <?php print $node->field_code[0]['view']; ?></div>
<div id="product_brand"><p>Brand: <?php print $node->taxonomy[16]->name; ?></p></div>
<div id="product_manufacturer"><p>Manufactured In: <?php print $node->field_manufactured_in[0]['view']; ?></p></div>
<div id="product_description"><?php print $node->content['body']['#value'];  ?></div>
<div id="product_image_info">Click Image to Enlarge</div>
<div id="product_pdf"><?php print $node->content['files']['#value']; ?></div>
<div id="product_price">(Effective 01/08/2008. May be subject to change without notice. Price shown excludes GST)<?php print $node->content['field_wholesale_price_single']['#value']; ?> <?php print $node->content['field_wholesale_price_multiple']['#value']; ?></div>

Can anyone help?

Thanks.

I think you want to use '#access' instead of 'view'. I had thought that 'view' was the actual content being displayed on the screen.

Thanks Lyle,
Been away for a while. Thanks for your help.

Tried replacing 'view' with 'access', and now it shows/hides the field title, but not the field value. I have uploaded the site to a web server: http://www.dtoomey.com/nam/node/1

Can't get past this one. Would anyone be able to give some further clues as to how this can be accomplished?

I've found a solution to this, for non-programmers like myself.

The problem had been solved with a drupal module called: 'cck field permissions'

I think I spoke too soon.

The module works perfectly, but if you've customized the product view using node-product.tpl.php (as I have), this overrides the permissions.

I'm back to square one now.

Hello Newb cousin!

You may be able to do it in your theme. In your node-whatever.tpl.php file you could have an if statement that would display the field only if the current user's uid isn't 0.

Hi Newbstah,

Many thanks. This was the way to do it, for sure.

I got some help over at #drupal-ubercart (a great irc community).

I'm going to list the steps here in the hope that it'll make someone else's life a bit easier.

I'm very thin on the ground with PHP and can only really alter working examples to achieve what I need to do.

Anyway, to get this working, I followed these steps:

• Add a CCK field to product page from: Administer > Content Management > Content Types

• Add a product and populate all your fields, including your added custom CCK field

• Place this code at the end of your node-product.tpl.php page:

<pre>
<?php // this will print the $node array at the bottom of each node take it out when finished ?>
<?php var_dump($node); ?>
</pre>

You'll find your node-product.tpl.php page in your working theme directory. This page can be customized to alter and theme your product pages.

Load a product page in your browser. At the end of the page you'll notice drupal has spat out a lot of raw PHP code. Through some trial and error, you need to pick up the PHP code which represents your custom CCK field.

Here's an example: $node->field_wholesale_details[0]['view']

• To display, theme or alter the display position of this field, you can use CSS and DIVs on your tpl.php page

• To hide this field based on whether or not a user is logged in, you can surround it with this code:

<?php
global $user;
if($user->uid != 0){
  print $node->field_wholesale_details[0]['view'];
} else {
  print "Log in to view wholesale information";
} ?>

As I understand it, the user id (uid) of 0 is assigned to anonymous users. So as per the above code, the field will only be displayed to users 1 >.

This is probably a rough way of doing this. I ideally wanted to create a custom module to achieve this, but I simply could not get it to work, after many weeks of effort and research.

Thanks to acm over at #drupal-ubercart for your help.
