PHP-SelectionGroup不添加额外的属性

我有PHP代码：

SelectionGroup::create(
//...
SelectionGroup_Item::create(/*...*/),
SelectionGroup_Item::create(/*...*/),
//...
)
->addExtraClass("some-extra-class")
->setAttribute('ng-change','log(myModel)')
->setAttribute('ng-model','myModel')

和呈现的html看起来像：

...
<ul class="SelectionGroup field CompositeField selectiongroup some-extra-class nolabel">
    ...
</ul>
...

我要添加额外的类,为什么不添加我的额外属性？

此SelectionGroup是FieldList的一部分,其他字段允许设置属性,而SelectionGroup_Item中的字段可以设置其属性,例如：

FieldList::create([
  HiddenField::create(...)->setAttribute("does","this work"),
  SelectionGroup::create(
    //...
    SelectionGroup_Item::create('name',
      FieldGroup::create(null,[
        HiddenField::create(...)->setAttribute("maybe","it does")
      ])
    ),
    SelectionGroup_Item::create(...),
    //...
  )
  ->addExtraClass("some-extra-class")
  ->setAttribute('ng-change','log(myModel)')
  ->setAttribute('ng-model','myModel')
])

呈现以下HTML：

...
<input type="hidden" ... does="this work" />
<ul class="SelectionGroup field CompositeField selectiongroup some-extra-class nolabel">
  ...
  <input type="hidden" ... maybe="it does" />
  ...
</ul>
...

解决方法:

在SilverStripe 3.4中,SelectionGroup_Item使用的默认模板中未调用$AttributesHTML变量.

SelectionGroup_Item使用CompositeField模板(因为它是extends CompositeField,并且在框架中没有设置自己的模板).

框架中当前的CompositeField模板在开始标记中不包含$AttributesHTML：

<$Tag class="CompositeField $extraClass <% if ColumnCount %>multicolumn<% end_if %>">
    <% if $Tag == 'fieldset' && $Legend %>
        <legend>$Legend</legend>
    <% end_if %>

    <% loop $FieldList %>
        <% if $ColumnCount %>
            <div class="column-{$ColumnCount} $FirstLast">
                $Field
            </div>
        <% else %>
            $Field
        <% end_if %>
    <% end_loop %>
</$Tag>

我们可以创建自己的SelectionGroup_Item模板或CompositeField来添加$AttributesHTML变量.

为此,我们在mysite / templates / includes目录中创建SelectionGroup_Item.ss文件.

mysite / templates / includes / SelectionGroup_Item.ss

<$Tag $AttributesHTML class="CompositeField $extraClass <% if ColumnCount %>multicolumn<% end_if %>">
    <% if $Tag == 'fieldset' && $Legend %>
        <legend>$Legend</legend>
    <% end_if %>

    <% loop $FieldList %>
        <% if $ColumnCount %>
            <div class="column-{$ColumnCount} $FirstLast">
                $Field
            </div>
        <% else %>
            $Field
        <% end_if %>
    <% end_loop %>
</$Tag>

创建此模板后,我们需要在页面URL中调用？flush = all,以使系统清除其缓存并找到此新模板.
