Check if CCK field is empty?

For empty, use the text comparison condition with your user reference field and a blank comparison pattern. For not empty, do the same but also check the "negate" option.

Could you please share your PHP snippet?
The solution in #1 doesn't work, because both fields in the text comparison condition form are required (cannot be left blank).

Thanks, that is useful information. I ended up using the "field has value" condition, with this code as the value:
return array( 0 => array('value' => NULL));

I'm not sure which solution is more 'efficient' but it's good to know they both work.

Thank you very much, obrienmd!!!!

After hours of research, your code in post #4 solved my problem.

<?php if($node->field_picture_accessoires[0]['view'] != NULL) { ?>
<div class="accessoires">
<h3>Accessoires</h3>
<?php foreach ($node->field_picture_accessoires as $picture_accessoires) { print $picture_accessoires['view']; } ?>
</div>
<?php } ?>

I just don't understand, why I get an error message, when i close with an "endif".

Hi Lucience,

You are getting error when closing if statement with endif as you are using curly braces to open and close the if statement. If you want to use endif then if statement should open with colons ":" like this :

<?php if($node->field_picture_accessoires[0]['view'] != NULL) : ?>
<div class="accessoires">
<h3>Accessoires</h3>
<?php foreach ($node->field_picture_accessoires as $picture_accessoires) { print $picture_accessoires['view']; } ?>
</div>
<?php endif; ?>

Hope this clear your doubt.

you can use print null; in the second field in the rules interface, this will print nothing. While the requirement is forfilled.

Instead of NULL, how can you rewrite this statement to return true if the field had data?

if (isset($node->field_your_name[0]['value'])) {
return TRUE;
}
else {
return FALSE;
}

Thank you!

Had same problem, but with random type fields. Came back here to share solution:

$filtered = array();
$function = $field['module'] .'_content_is_empty';
foreach ((array) $node->$field['field_name'] as $delta => $item) {
  if (!$function($item, $field)) {
    $filtered[] = $item;
  }
}
if (empty($filtered)) {
  // field is empty
}   

We discussed this issue in a PHP community especially to determine a way that can give a true response in situations where the field might be empty (in human terms), but there is some markup in it (&nbsp,

The first proposed solution will work (doing it using Textual Comparison) if you check "Evaluate as RegEx" and enter ^$ as the pattern, which matches an empty string.
