Метки поля внутри поля Drupal 9

Аватар пользователя Babich Babich 19 мая в 6:46

Здравствуйте, решил спрятать метки поля внутрь поля для красоты. Для 7 версии был модуль Form Placeholder. Для 9 версии такого модуля не нашел. Добавил вот такую конструкцию

<?php/**
 * Implements template_preprocess_input().
 */
function THEMENAME_preprocess_input(&$variables) {
  if ($variables['attributes']['type'] == 'text') {
    $variables['attributes']['placeholder'] = $variables['element']['#title']; 
  }
}?>

Подскажите пожалуйста, как спрятать метки во внутрь поля у всех типов, а не только у текстового. Может быть есть другой способ.

</div>

Так мы поменяем местами input и label. Далее стилизуем с помощью css.

А в восьмёрке/девятке разве плейсхолдеры не в ядре? У меня для полей формы можно прямо в админке задать плейсхолдеры, и ничего специального я для этого не ставил.
PS Красота кстати весьма сомнительная. В пустой форме видно что куда вводить, а если форма уже заполнена, то иногда трудно понять что где и зачем.

В идеале, чтобы из плейсхолдера, при заполнении название переносилось вверх. Как на сайте сдека например.

Можно сделать на чистом css. Но для этого нужно поменять местами input и label. Как это сделать?

перенести {% if label_display in ['before', 'invisible'] %}
{{ label }}
{% endif %} вниз, но тогда появляется закрывающийся тег у Input. Не понимаю почему.
