I'm writing a module to change input HTML attributes with the next code:

use Drupal\Core\Form\FormStateInterface;

 * Implements hook_form_alter().
function custom_numeric_filter_form_alter(&$form, FormStateInterface $form_state, $form_id) {
  $field = 'yourfieldname';
  if ($form_id == 'views_exposed_form' && array_key_exists($field, $form)) {
    $form[$field]['#type'] = "range";
    $form[$field]['#step'] = 5;
    $form[$field]['#size'] = 5;
    $form[$field]['#min'] = 10;
    $form[$field]['#max'] = 60;

The problem is that the type gets overwritten back to number by something else.

I have Better Exposed Filters installed, maybe it gets rewritten there but why? And how can I make sure my module code has priority? With the help from NoSssweat I made sure it was executed after BEF and it didn't help.

    How can I make sure my module code has priority? By giving your module higher weight so your hook executes last. You can achieve that like this or with this

  • @NoSssweat thanks, is there a way to see all these weights for installed modules?

  • It was after BEF but I still changed the weight, cleared the cache and it didn't help unfortunately. Maybe it's something else. Like range being an unknown value for some reason.

  • Try setting type to BETWEEN, just a guess.

Try in this way:

function seven_form_alter(&$form, FormStateInterface $form_state, $form_id) {
  if (in_array($form_id, ['node_page_form', 'node_page_edit_form'])) {
    $form['field_number']['widget'][0]['value']['#type'] = 'range';
