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。表格工作正常。但我需要为我的一些字段添加field dependency。

如果zipbasedprice_isrange字段设置为yes，则需要显示其他两个字段，如果设置为no，则只显示一个字段。

我怎样才能使用下面的表格来实现呢？

字段依赖关系应在zipbasedprice_isrange、zipbasedprice_zip、zipbasedprice_zip_from_zip 和zipbasedprice_zip_to_zip 之间。

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');
    
    $fieldset->addField('zipbasedprice_country', 'select', array(
                    'name' => 'zipbasedprice_country',
                    'label' => Mage::helper('zipbasedprice')->__('Country'),
                    'values'    => Mage::getModel('adminhtml/system_config_source_country')->toOptionArray(),

         ));
    
    $regions = array();
    $regions['*'] = '*';
$regionList = Mage::getModel('directory/region')->getResourceCollection()->addCountryFilter('IN')->load();
foreach($regionList as $region){ $regions[$region['code']] = $region['default_name']; }
    
    $fieldset->addField('zipbasedprice_state', 'select', array(

Answer 1

考虑此示例仅在选择Specified选项时才显示文本字段。

$form = new Varien_Data_Form();

$form->addField('yesno', 'select', array(
    'label'  => $this->__('Yes or No?'),
    'values' => Mage::model('adminhtml/system_config_source_yesnocustom')
        ->toOptionArray(),
));

$form->addField('custom_value', text, array(
    'label'  => $this->__('Other'),
));

// Append dependency javascript
$this->setChild('form_after', $this->getLayout()
    ->createBlock('adminhtml/widget_form_element_dependence')
        ->addFieldMap('yesno', 'yesno')
        ->addFieldMap('custom_value', 'custom_value')
        ->addFieldDependence('custom_value', 'yesno', 2) // 2 = 'Specified'
);

depends - 此节点包含当前字段与其他字段的依赖关系列表。这个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。比如这样的配置：

<depends>
     <field_name>1</field_name>
</depends>

上面将添加规则，仅当名为field_name的字段的值等于1时才显示当前字段。

我想扩展@Slimshadddyyy 的答案，再举一个具有多个依赖值的示例。

$fieldset->addField("transfer_interval", "select", array(
    "label" => Mage::helper("core")->__("Transfer Interval"),
    "name" => "transfer_interval",
    "class" => "required-entry",
    'values' => array(
        array(
            'value' => 'daily',
            'label' => Mage::helper('core')->__('Daily'),
        ),
        array(
            'value' => 'weekly',
            'label' => Mage::helper('core')->__('Weekly'),
        ),
        array(
            'value' => 'monthly',
            'label' => Mage::helper('core')->__('Monthly'),
        )
    ),
    "required" => true,
));

$fieldset->addField("transfer_day_weekly", "select", array(
    "label" => Mage::helper("core")->__("Transfer Day"),
    "name" => "transfer_day_weekly",
    "class" => "required-entry",
    'values' => $this->getWeekDays(), // Pay attention here you need to change this for your array values
    "required" => true,
));

$fieldset->addField("transfer_day_monthly", "select", array(
    "label" => Mage::helper("core")->__("Transfer Day"),
    "name" => "transfer_day_monthly",
    "class" => "required-entry",
    'values' => $this->getMontlyDays(), // Pay attention here you need to change this for your array values
    "required" => true,
));

// Append dependency javascript
$this->setChild('form_after', $this->getLayout()
    ->createBlock('adminhtml/widget_form_element_dependence')
    ->addFieldMap('transfer_interval', 'transfer_interval') // Putting fields for mapping
    ->addFieldMap('transfer_day_weekly', 'transfer_day_weekly')
    ->addFieldMap('transfer_day_monthly', 'transfer_day_monthly')
    ->addFieldDependence('transfer_day_weekly', 'transfer_interval', 'weekly') // Pay attetion below as you can add more than one dependence
    ->addFieldDependence('transfer_day_monthly', 'transfer_interval', 'monthly')
);

在此示例中，当您选择“每周”时，它将显示带有每周选项的字段，因此如果您选择“每月”选项。

Answer 3

有不同的方法可以做到这一点。最简单和最简单的方法是将onclick 属性添加到另一个字段所依赖的字段。即

$fieldset->addField('zipbasedprice_isrange', 'select', array(
    'name' => 'zipbasedprice_isrange',
    'label' => Mage::helper('zipbasedprice')->__('Is Range?'),
    ......
    'onclick' => someFunction();

然后定义 someFunction() 以实现您的需要。
