You misread the documentation, I assume.
hiddenFieldis to enable/disable specific hidden fields for specific form fields.
你误读了文档，我想。
hiddenField是启用/禁用特定表单字段的特定隐藏字段。
You are either looking for
你要么正在寻找
$this->Form->hidden('group_id')
or
或者
$this->Form->input('group_id', ['type' => 'hidden']);
I usually only use the latter.
我通常只使用后者。
See http://book.cakephp.org/2.0/en/core-libraries/helpers/form.html

BUT - that said - you shouldnt actually use either one of those. And omit any fields that serve no real purpose for the view and its form. Instead you should inject those fields into the data array prior to saving. See http://www.dereuromark.de/2010/06/23/working-with-forms/
但是 - 也就是说 - 你实际上不应该使用其中任何一个。并省略对视图及其形式没有实际用途的任何字段。相反，您应该在保存之前将这些字段注入到数据数组中。见http://www.dereuromark.de/2010/06/23/working-with-forms/

If you are looking to add a hidden field that uses a related second data array that will not be passed via post or put by default, you can use this to pass it:
如果您要添加一个隐藏字段，该字段使用相关的第二个数据数组，默认情况下不会通过 post 或 put 传递，您可以使用它来传递它：
echo $this->Form->hidden('Group.name');
This is useful for echoing out edit page titles when the post or put encounters an error. A dynamic title can lose Group.namedata array when your form is set up such as this:
这对于在 post 或 put 遇到错误时回显编辑页面标题很有用。Group.name当您的表单设置如下时，动态标题可能会丢失数据数组：
<h1>Edit Group - <?php echo h($this->request->data['Group']['name']); ?></h1>
For data that is to be saved to db however, follow Mark's suggestion above.
但是，对于要保存到 db 的数据，请遵循上面 Mark 的建议。
