[英]How to create a new widget for a Paragraph field programmatically in an AJAX handler Drupal 8
I need to add Paragraph fields programmatically to an entity in an AJAX handler. 我需要以编程方式将“段落”字段添加到AJAX处理程序中的实体。
This is my AJAX callback: 这是我的AJAX回调:
function myAjaxCallback(array &$form, \Drupal\Core\Form\FormState $form_state) {
$paragraph3 = \Drupal\paragraphs\Entity\Paragraph::create([
'type' => 'media',
'field_caption' => 'Apart from the included Paragraph types, you can create your own simply by going to Structure -> Paragraphs types.',
]);
$paragraph3->save();
// Now I need to add $paragraph3 to $form['field_gallery_items']['widget']
return $form;
}
I need to add the new Paragraph I created to the widget so that when the $form is returned I have added a paragraph. 我需要将我创建的新段落添加到小部件中,以便在返回$ form时添加一个段落。
How Can I do that? 我怎样才能做到这一点?
尝试将段落追加到表单字段
$form['field_gallery_items']['widget']->appendItem($paragraph3);
