查找多值字段的长度 [英] finding length of multi-value field

问题描述

我在drupal节点中有一个多值cck字段。该字段称为 field_multip 。我需要知道这个字段中的项目数量，例如下面的例子3中的

我会以为 length 会做这个伎俩，但是$ code> $ node-> field_multip.length 也不是$ code $ $ node-> field_multip.length（） code>为我工作。

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

解决方案

你想使用 count（）

  $ itemcount = count $节点 - > field_multip）; 
  

应该这样做。

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]

解决方案

You want to use count()

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

Should do it.
