在 magento 中创建管理表单字段之间的依赖关系不起作用

Question

这是一个管理表单，我在其中添加了一个自定义选项卡，以便向其中添加一些自定义字段。该表格工作正常。但我需要添加field dependency一些字段。

如果该字段zipbasedprice_isrange设置为yes，那么我需要显示其他两个字段；如果它设置为no，则只应显示一个字段。

我如何使用下面的表格来实现这一点？

字段依赖关系应位于zipbasedprice_isrange, zipbasedprice_zip, zipbasedprice_zip_from_zip&之间zipbasedprice_zip_to_zip。

public function getFormHtml() {
        $form = new Varien_Data_Form(
            array('id' => 'edit_form', 'action' => $this->getData('action'), 'method' => 'post')
        );
    
            $this->getLayout()->createBlock('adminhtml/widget_form_renderer_element').
            $this->getLayout()->createBlock('adminhtml/widget_form_renderer_fieldset').
            $this->getLayout()->createBlock('adminhtml/widget_form_renderer_fieldset_element');


    $fieldset = $form->addFieldset('zipbasedprice_fields', array('legend' => Mage::helper('zipbasedprice')->__('Zip Based Price'))

    $default_country = array('label' => 'IN', 'code' => 'India');

Specified考虑此示例，仅在选择该选项时显示文本字段。

\n\n

$form = new Varien_Data_Form();\n\n$form->addField('yesno', 'select', array(\n    'label'  => $this->__('Yes or No?'),\n    'values' => Mage::model('adminhtml/system_config_source_yesnocustom')\n        ->toOptionArray(),\n));\n\n$form->addField('custom_value', text, array(\n    'label'  => $this->__('Other'),\n));\n\n// Append dependency javascript\n$this->setChild('form_after', $this->getLayout()\n    ->createBlock('adminhtml/widget_form_element_dependence')\n        ->addFieldMap('yesno', 'yesno')\n        ->addFieldMap('custom_value', 'custom_value')\n        ->addFieldDependence('custom_value', 'yesno', 2) // 2 = 'Specified'\n);\n

\n\n

depends\xe2\x80\x93 该节点包含当前字段对其他字段的依赖关系列表。该节点的结构非常简单。子节点名称是该字段所依赖的字段名称，节点值是使该字段可见的值。例如这样的配置：

\n\n

<depends>\n     <field_name>1</field_name>\n</depends>\n

\n\n

上面将添加仅当字段值调用时显示当前字段的规则field_name等于1时显示当前字段的规则。
