Drupal 7 - 注意：未定义索引：und in include（）

Question

I'm getting this error: Notice: Undefined index: und in include() (line 24 of /home/cliffdwellerproductions/dev.cliffdwellerdigital.com/Dahl/sites/all/themes/basic/templates/node--page2.tpl.php).

the code is:

if ($node->field_body_left !== NULL) : 
$text = trim($node->field_body_left['und']['0']['value']);
else:
$text = '';

Please help, as I haven't been able to define the variable...

Answer 1

Your $node->field_body_left variable is existent but it doesn't have an 'und' element.
