finding length of multi-value field

问题:

I have a multi-value cck field in a drupal node. The field is called field_multip. I need to know the number of items in this field, for example 3 in the case below

I would have thought that length would do the trick, but neither $node->field_multip.length nor $node->field_multip.length() worked for me.

field_multip
   [0] 
      [id]
      [sec]
   [1]
      [id]
      [sec]
   [2]
      [id]
      [sec]

You want to use count()

$itemcount = count($node->field_multip);

Should do it.
