Drupal 7 CCK feilds deconstruction from $content in node.tpl.php file-Collection of common programming errors

After a long quest, finally I got the solution for splitting $content in Drupal 7 in node.tpl.php.

Previously i was using i was using :-

print $node->field_name['und'][0]['value'];

Which was giving a warning :-

Notice: Undefined offset: 0 in include() (line 24 of C:\xampp\htdocs\drup\sites\all\themes\myCustomTheme\node.tpl.php)

Now I am using the function below which works fine with no errors

$output= field_get_items('node', $node, 'field_name');
$output = $output[0]['safe_value'];
print $output;

Now the problem is I have more than 50 fields on the page , I don’t think it would be efficient to call field_get_items(‘node’, $node, ‘field_name’) function 50 times.

Whats the alternate ? OR should I strict to the field_get_items function OR should I strict to the print $node->field_name[‘und’][0][‘value’]; which I heard is not good to use in Drupal 7 as und is undefined. This though solves my problem but gives irritating warnings.

1. In your template you should have access to the variables that are preprocessed earlier.

   Each of your field is actually a variable so you can do $field_name[LANGUAGE_NONE][0][‘safe_value’]

   To get rid of error notices, I suggest that you use the isset() function
