Views reset button creates anonymous sessions

Open on Drupal.org →
Created on 11 August 2025, 2 months ago

Problem/Motivation

When BEF is used within a view that includes a reset button within the exposed filters, BEF is creating anonymous sessions.

This was originally identified as an issue within core that was fixed in in 2025. https://www.drupal.org/project/drupal/issues/3471220 🐛 Views exposed filter reset creates session for anonymous Active

The specific code that was updated/fixed in core, still exists within the BEF module.

Steps to reproduce

  1. Find a form that includes a reset button and open it in a different browser.
  2. Ping the database using drush sql:cli to get a count on anonymous sessions.
    SELECT count(*) FROM sessions WHERE uid = 0;
    You can use this to look closer at them.
    SELECT * FROM sessions WHERE uid = 0 ORDER BY timestamp DESC;
  3. Click the reset button.
  4. Run the 2 sql:cli commands again.
  5. Note the sessions count increases, and a new session is created in the database.

Proposed resolution

Within docroot/modules/contrib/better_exposed_filters/src/Plugin/views/exposed_form/BetterExposedFilters.php, make the same changes that were made within core.

Here is a snippet from the core issue:

The code in question is in \Drupal\views\Plugin\views\exposed_form\ExposedFormPluginBase::resetForm

  $session = $this->view->getRequest()->getSession();
    $views_session = $session->get('views', []);
    if (isset($views_session[$this->view->storage->id()][$display_id])) {
      unset($views_session[$this->view->storage->id()][$display_id]);
    }
    $session->set('views', $views_session);

The issue is the unqualified call to set the session

$session->set('views', $views_session);

This should be

if (!empty($views_session)) {
    $session->set('views', $views_session);
}
else {
    $session->remove('views');
}
