Drupal 表单中字段集的渲染顺序

Question

我有一个表单，它根据计数变量在 Fieldset 中创建多个条目 $form_state['num_entries']。它包含一个用于区域的文本字段、一个滑块元素和一个用于滑块值的隐藏字段。

我需要渲染顺序为：文本域，滑块，隐藏字段。

但是表单只渲染所有区域，然后是所有滑块等等。如何修复渲染顺序？

提前感谢您抽出时间！

  for ($i = 0; $i < $form_state['num_entries']; $i++) {


    $form['region_fieldset']['places'][$i] = [
      '#type' => 'textfield',
      '#title' => "Region" . " " . ($i + 1),
      '#size' => 22,
      '#attributes' => ['multiple' => 'multiple'],
      '#default_value' => isset($default_values["regions"][$i]) ? $default_values["regions"][$i] : '',

    ];

    $form['region_fieldset']["radius_slider"][$i] = [
      '#type' => 'slider_form_element_field',
      '#title' => 'Radius',
      '#attributes' => ['multiple' => 'multiple', 'id' => "slider_" . $i],
      '#default_value' =>  40,
    ];

    $form['region_fieldset']['slider_value'][$i] = [
      '#type' => 'hidden',
      '#default_value' => isset($form['entry_fieldset']["test-slider"]["#default_value"]) ? $form['entry_fieldset']["test-slider"]["#default_value"] : 40,
      '#attributes' => [
        'class' => ['slider-hidden-value'],
        'multiple' => 'multiple',
        'id' => "slider_value_" . $i,
      ],
    ];
  }

好的，我找到了。数组中键的顺序有误。正确的方法是：

 for ($i = 0; $i < $form_state['num_entries']; $i++) {


    $form['region_fieldset']['regions'][$i]["places"] = [
      '#type' => 'textfield',
      '#title' => "Region" . " " . ($i + 1),
      '#size' => 22,
      '#attributes' => ['multiple' => 'multiple'],
      '#default_value' => isset($default_values["regions"][$i]) ? $default_values["regions"][$i] : '',

    ];

    $form['region_fieldset']["regions"[$i]["radius_slider"]] = [
      '#type' => 'slider_form_element_field',
      '#title' => 'Radius',
      '#attributes' => ['multiple' => 'multiple', 'id' => "slider_" . $i],
      '#default_value' =>  40,
    ];

    $form['region_fieldset']["regions][$i]["slider_value"] = [
      '#type' => 'hidden',
      '#default_value' => isset($form['entry_fieldset']["test-slider"]["#default_value"]) ? $form['entry_fieldset']["test-slider"]["#default_value"] : 40,
      '#attributes' => [
        'class' => ['slider-hidden-value'],
        'multiple' => 'multiple',
        'id' => "slider_value_" . $i,
      ],
    ];
  }
