Question

是否可以隐藏/禁用Widget中的参数？在CMS页面上放置窗口小部件时，您会看到窗口小部件参数，您可以选择各种选项。在我的一个小部件中，如果特定模块不活动，我想隐藏一个参数。（我知道如何检查模块是否处于活动状态）我还想从模板下拉列表中删除选项值。删除使用缺少的模块的模板。有Magento方式吗？使用Magento Enterprise 1.12.0.2

您可以通过位于模块的etc文件夹中的模块widget.xml来执行此操作。例如在我的情况下，我想显示选择器选择/关联事件（我的自定义模块中的实体）与小部件，所以我这样做了如下

在我的小部件块下（在widget.xml中）我添加了如下所示的参数：

 <eventsmanager_event_view type="tpl_eventsmanager/event_widget_view" translate="name description" module="tpl_eventsmanager">
        <name>Event Calendar</name>
        <description>Event Calendar widget</description>
        <is_email_compatible>0</is_email_compatible>
      <parameters>
            <event_id type="complex" translate="label">
                <visible>1</visible>
                <required>1</required>
                <label>Event</label>
                <type>label</type>
                <helper_block>
                    <type>tpl_eventsmanager/adminhtml_event_widget_chooser</type>
                    <data>
                        <button translate="open">
                            <open>Select Event</open>
                        </button>
                    </data>
                </helper_block>
                <sort_order>120</sort_order>
            </event_id>
        </parameters>
    </eventsmanager_event_view>

然后我添加了包含此代码的文件chooser.php：

<?php
class Tpl_EventsManager_Block_Adminhtml_Event_Widget_Chooser extends Mage_Adminhtml_Block_Widget_Grid

    /**

    public function __construct($arguments=array())
    {
        parent::__construct($arguments);
        $this->setDefaultSort('entity_id');
        $this->setDefaultDir('ASC');
        $this->setUseAjax(true);
        $this->setDefaultFilter(array('chooser_status' => '1'));
    }

    public function prepareElementHtml(Varien_Data_Form_Element_Abstract $element)
    {
        $uniqId = Mage::helper('core')->uniqHash($element->getId());
        $sourceUrl = $this->getUrl(
            '*/eventsmanager_event_widget/chooser',
            array('uniq_id' => $uniqId)
        );
        $chooser = $this->getLayout()->createBlock('widget/adminhtml_widget_chooser')
            ->setElement($element)
            ->setTranslationHelper($this->getTranslationHelper())
            ->setConfig($this->getConfig())
            ->setFieldsetId($this->getFieldsetId())
            ->setSourceUrl($sourceUrl)
            ->setUniqId($uniqId);
        if ($element->getValue()) {
            $event = Mage::getModel('tpl_eventsmanager/event')->load($element->getValue());
            if ($event->getId()) {
                $chooser->setLabel($event->getEventName());
            }
        }
        $element->setData('after_element_html', $chooser->toHtml());
        return $element;
    }

Magento Widget.xml，禁用或隐藏参数
