我的自定义Ajax表单未带定义的默认值

Question

我正在创建一个自定义实体配置，除#default_values“属性不起作用外，其他一切都很好。我尝试了几种方法解决该问题，即买东西没有任何作用。

不起作用的字段是循环内的以下字段：“宽度”，“高度”和“设备”

附上我的Php代码。

public function form(array $form, FormStateInterface $form_state) {
$form = parent::form($form, $form_state);
$default_entity = $this->entity;
$form['label'] = [
  '#type' => 'textfield',
  '#title' => $this->t('Name'),
  '#maxlength' => 255,
  '#default_value' => $default_entity->label(),
  '#description' => $this->t("Label for the Default entity."),
  '#required' => TRUE,
 ];
$form['id'] = [
  '#type' => 'machine_name',
  '#default_value' => $default_entity->id(),
  '#machine_name' => [
    'exists' => '\Drupal\publicity\Entity\DefaultEntity::load',
  ],
  '#disabled' => !$default_entity->isNew(),
];
$form['url']=[
  '#type'=>'url',
  '#title'=>t('Url'),
  '#description'=>'Add a custom url for your configuration',
  '#default_value'=>$default_entity->get('url'),
];
$form['id_publicity']=[
  '#type'=>'textfield',
  '#title'=>$this->t('ID Publicity'),
  '#default_value'=> $default_entity->get('id_publicity'),
  '#placeholder'=>$this->t('Ej: XUY-146'),
];
$form['render_section']=[
  '#type'=> 'select',
  '#default_value'=> $default_entity->get('render_section'),
  '#options'=>[
    'Home Page','Article','Sections',
  ],
  '#empty_option'=>'Render Sections',
];
// Gather the number of breakpoints in the form already.
$fields = $form_state->get('fields');
// We have to ensure that there is at least one name field.
if ($fields === NULL) {
  $name_field = $form_state->set('fields', 1);
  $fields = 1;
}
$form['#tree'] = TRUE;
$form['breakpoints'] = [
  '#type' => 'fieldset',
  '#title' => $this->t('RENDERED'),
  '#prefix' => '<div id="breakpoints-fieldset-wrapper">',
  '#suffix' => '</div>',
];

  for ($i = 0; $i < $fields; $i++) {
  $form['breakpoints']['subfieldset'][$i] = [
  '#type' => 'fieldset',
  '#title' => $this->t('RESPONSIVE DESIGN'),
  ];
  $form['breakpoints']['subfieldset'][$i]['width'] = [
    '#type' => 'number',
    '#title' => $this->t('Width'),
    '#placeholder'=>$this->t('Ej: 720px'),
    '#default_value'=> $default_entity->get('width'),
  ];
  $form['breakpoints']['subfieldset'][$i]['height'] = [
    '#type' => 'number',
    '#title' => $this->t('Height'),
    '#placeholder'=> $this->t('Ej: 1080px'),
    '#default_value'=> $default_entity->get('height'),
  ];
  $form['breakpoints']['subfieldset'][$i]['device']=[
  '#type'=>'select',
  '#options'=>[
    'Desktop','Mobile','Tablet',
  ],
  '#title'=>t('Device'),
  '#default_value'=> $default_entity->get('device'),
  '#placeholder'=>$this->t('Custom Devices'),
  '#empty_option'=>$this->t('Devices List'),
  ];
}
$form['breakpoints']['actions'] = [
  '#type' => 'actions',
];
$form['breakpoints']['actions']['add_name'] = [
  '#type' => 'submit',
  '#value' => $this->t('Add one more'),
  '#submit' => ['::addOne'],
  '#ajax' => [
    'callback' => '::addmoreCallback',
    'wrapper' => 'breakpoints-fieldset-wrapper',
  ],
];
// If there is more than one name, add the remove button.
if ($fields > 1) {
  $form['breakpoints']['actions']['remove_name'] = [
    '#type' => 'submit',
    '#value' => $this->t('Remove one'),
    '#submit' => ['::removeCallback'],
    '#ajax' => [
      'callback' => '::addmoreCallback',
      'wrapper' => 'breakpoints-fieldset-wrapper',
    ],
  ];
}
$form['breakpoints']['actions']['submit'] = [
  '#type' => 'submit',
  '#value' => $this->t('Submit'),
];
return $form;
}

我需要默认值属性由用户或填写配置表格的人带来所选值。
