I have created a custom form using FormBase. In which there are 3 fields City, State & Country. I've created taxanomy for these 3 fields. Now i want to create autocomplete field which will fetch data from database from taxanomy and also add the the term to taxanomy if not exist in the table. Please help me with these. Below is the code :
HotelForm.php under src/Form directory
/**
* @file
* Contains \Drupal\hotel_form\Form\HotelForm
*/
namespace Drupal\hotel_form\Form;
use Drupal\Core\Form\FormBase;
use Drupal\Core\Form\FormStateInterface;
use Drupal\Core\Url;
class HotelForm extends FormBase {
public function getFormId() {
return 'hotel';
}
public function buildForm(array $form, FormStateInterface $form_state) {
$form['hotel_title'] = array(
'#type' => 'textfield',
'#size' => 50,
'#title' => t('Hotel Name'),
'#required' => TRUE,
'#placeholder' => t('Hotel Name'),
);
$form['hotel_city'] = array(
'#type' => 'entity_autocomplete',
'#target_type' => 'node',
'#size' => 50,
'#title' => 'City',
'#required' => TRUE,
'#placeholder' => t('City'),
);
$form['hotel_state'] = array(
'#type' => 'textfield',
'#size' => 50,
'#title' => t('State'),
'#required' => TRUE,
'#placeholder' => t('State'),
);
$form['hotel_country'] = array(
'#type' => 'textfield',
'#size' => 50,
'#title' => t('Country'),
'#required' => TRUE,
'#placeholder' => t('Country'),
);
$form['hotel_mobile'] = array(
'#type' => 'number',
'#title' => t('Mobile Number'),
'#required' => TRUE,
'#placeholder' => t('Mobile Number'),
);
$form['hotel_phone'] = array(
'#type' => 'number',
'#title' => t('Phone Number'),
'#required' => TRUE,
'#placeholder' => t('Phone Number'),
);
$form['submit'] = array(
'#type' => 'submit',
'#value' => t('Submit'),
'#attributes' => array(
'class' => array('btn btn-submit'),
),
);
return $form;
}
public function validateForm(array &$form, FormStateInterface $form_state) {

_title: 'Hotel Form'
_form: 'Drupal\hotel_form\Form\HotelForm'
requirements:
_permission: 'access content'
Thanks
