删除电话作为运输必填字段，但不向 Magento 计费

Question

如何使电话字段在发货时不需要，但在单页结帐时需要在账单上？

我关注了许多指向以下方法的论坛，但这会禁用计费和运输所需的元素？

我不知道任何允许这样做的扩展。如果你想让它工作，你应该使用Mage_Customer_Model_Form。在结帐过程中，magento 调用此模型的 validateData() 方法。此方法在Mage_Eav_Model_Form 中定义。您需要重写另一个模型，即Mage_Sales_Model_Quote_Address，因为它的父Mage_Customer_Model_Address_Abstract 有一个valid() 方法来检查电话是否不是空的。因此，假设您已删除此属性的 is_required 和 validation_rules

在一个模块etc/config.xml

<config>
  <global>
    <models>
      <customer>
        <rewrite>
          <form>YourNamespace_YourModule_Model_Customer_Form</form>
        </rewrite>
      </customer>
      <sales>
        <rewrite>
          <quote_address>YourNamespace_YourModule_Model_Quote_Address</quote_address>
        </rewrite>
      </sales>
    </models>
  </global>
</config>

在YourNamespace/YourModule/Model/Customer/Form.php

class YourNamespace_YourModule_Model_Customer_Form extends Mage_Customer_Model_Form {

  public function validateData(array $data) {
    //perform parent validation
    $result = parent::validateData($data);

    //checking billing address; perform additional validation
    if ($this->getEntity()->getAddressType() == Mage_Sales_Model_Quote_Address::TYPE_BILLING) {
      $valid = $this->_validatePhoneForBilling($data);          
      if ($result !== true && $valid !== true) {
        $result[] = $valid;
      }
      elseif ($result === true && $valid !== true) {
        $result = $valid;
      }
    }

    return $result;
  }

  protected function _validatePhoneForBilling($data) {
    $errors     = array();
    if (empty($data['telephone'])) {
      $attribute  = $this->getAttribute('telephone');
      $label      = Mage::helper('eav')->__($attribute->getStoreLabel());
      $errors[] = Mage::helper('eav')->__('"%s" is a required value.', $label);
    }
    if (empty($errors)) {
      return true;
    }
    return $errors;

  }
}

在YourNamespace/YourModule/Model/Quote/Address.php

class YourNamespace_YourModule_Model_Quote_Address extends Mage_Sales_Model_Quote_Address {
  public function validate() {
    if ($this->getAddressType() == self::TYPE_SHIPPING) {
      $result = parent::validate();
      $errorMsg = Mage::helper('customer')->__('Please enter the telephone number.');
      if (is_array($result) && in_array($errorMsg, $result)) {
        $result = array_diff($result, array($errorMsg));
      }          
      if (empty($result)) {
        return true;
      }
      return $result;
    }
    else {
      return parent::validate();
    }
  }
}
