如何隐藏fieldset元素的特定子元素？

Question

我只需要隐藏一个fieldset元素的两个子节点中的一个。

我遇到了将#type ='hidden'值分配给字段集的2个子元素的问题。

换句话说，我有：

Array
(
    [4] => Array
        (
            [#type] => hidden
            [#title] => Distribution Product
            [#default_value] => Array
                (
                )

            [#options] => Array
                (
                    [] => - None selected -
                    [0] => stdClass Object
                        (
                            [option] => Array
                                (
                                    [38] => Cosmetics
                                )

                        )

                    [1] => stdClass Object
                        (
                            [option] => Array
                                (
                                    [39] => Hair
                                )

                        )

                )

            [#description] => 
            [#multiple] => 0
            [#size] => 0
            [#weight] => 0
            [#theme] => taxonomy_term_select
            [#required] => 0
        )

    [1] => Array
        (
            [#type] => select
            [#title] => Product
            [#default_value] => Array
                (
                    [0] => 26
                )

            [#options] => Array
                (
                    [] => - None selected -
                    [0] => stdClass Object
                        (
                            [option] => Array
                                (
                                    [28] => Cosmetics
                                )

                        )

                    [1] => stdClass Object
                        (
                            [option] => Array
                                (
                                    [26] => -Joelle Ciocco
                                )

                        )


                )

            [#description] => 
            [#multiple] => 0
            [#size] => 0
            [#weight] => 0
            [#theme] => taxonomy_term_select
            [#required] => 0
        )

    [#type] => fieldset
    [#title] => Vocabularies
    [#collapsible] => 1
    [#collapsed] => 
    [#weight] => -3
    [#tree] => 1
)

我现在正在分配

$form['taxonomy'][4]['#type'] = 'hidden';
$form['taxonomy'][1]['#type'] = 'hidden';

但它们都是可见的。

当然如果我隐藏

$form['taxonomy']['#type'] = 'hidden';

它有效，我隐藏了一切。

感谢

如果你尝试

怎么办？

unset($form['taxonomy'][4]);
