Question

我正在从Drupal示例文件创建一个向导，并希望重构在设置选项和无线电等项目时重复的代码段。

我已经尝试过一个简单的函数传递“普通”和“优先”，但找不到让它工作的方法。

有人可以告诉我最佳方法吗？

无需考虑的代码如下：

function services_wizard_share_capital_classes($form, &$form_state) {

$form['share_classes']['type_of_class'] = array(
'#type' => 'select',
'#title' => t('What type of share will this class be?'),
'#options' => array(
  1 => t('Ordinary'),
  2 => t('Preferential'),
),
);

$form['ordinary']['share_type'] = array(
'#type' => 'item',
'#description' => t("You chose Ordinary Shares"),
'#states' => array(
  'visible' => array(
    ':input[name="type_of_class"]' => array('value' => '1'),
  ),
),
);

$form['preferential']['share_type'] = array(
'#type' => 'item',
'#description' => t("You chose Preferential Shares"),
'#states' => array(
  'visible' => array(
    ':input[name="type_of_class"]' => array('value' => '2'),
  ),
),
);
return $form;
}

我不确定这是最好的方法，但它肯定是重构代码的方法：

function _services_wizard_share_capital_classes_add_el(&$form, $name, $description, $index) {
  $form[$name]['share_type'] = array(
    '#type' => 'item',
    '#description' => t($description),
    '#states' => array(
      'visible' => array(
        ':input[name="type_of_class"]' => array('value' => "$index"),
      ),
    )
  );
}

function services_wizard_share_capital_classes($form, &$form_state) {
  // Other code

  _services_wizard_share_capital_classes_add_el($form, 'ordinary', 'You chose Ordinary Shares', 1);
  _services_wizard_share_capital_classes_add_el($form, 'preferential', 'You chose Preferential Shares', 2);
  // etc...
}
