Drupal 7 - node custom display

Question

I've got this problem. I've created file node--mycontenttype.tpl.php to display nodes in custom way. I've listed all the $content array by print_r($content). I can display all the variables except CCK fields. For example I can print out node type like:

<?php print $content['body']['#bundle']; ?>

But if I try to display any CCK field like:

<?php print $content['body']['#object']->field_url[und][0]['value']; ?>

It gives me an error "Notice: Use of undefined constant und - assumed 'und' w include()". Alright, so the "und" means "undefined" for langauge, but nor 'pl', nor 'en' solves the problem. How can I manage this?

Answer 1

Alright, after researching I've finally found an answer. It works, but in some cases it look a bit inefficient. Code goes like this:

<?php 
$output = field_get_items('node', $node, 'field_url');
$output = $output[0]['safe_value'];
print $output;
?>

But if you have a lot of CCK fields it looks like you have to launch field_get_items() function a lot of times. If any of you knows a better approach it could be nice you could share.

Answer 2

When you write [und] Drupal (PHP) assumes that there's variable $und defined somewhere in the code.

You should use:

<?php print $content['body']['#object']->field_url['und'][0]['value']; ?>
