- Merge request !25Issue #3159875: MissingMandatoryParametersException with BEF Links and taxonomy/term/% → (Closed) created by podarok
HI. When setting up BEF for exposed sort displayed as LINKS, then getting this error and blank page:
Symfony\Component\Routing\Exception\MissingMandatoryParametersException: Some mandatory parameters are missing ("arg_0") to generate a URL for route
The problem can be solved by not using exposed sort as link or if I change one line BetterExposedFiltersWidgetBase.php getExposedFormActionUrl() function like this. But not sure if it is the right solution. Just temporary fix. Can someone provide a patch with correct solution, please?
protected function getExposedFormActionUrl(FormStateInterface $form_state) {
/** @var \Drupal\views\ViewExecutable $view */
$view = $form_state->get('view');
$display = $form_state->get('display');
//if (isset($display['display_options']['path'])) {
if (isset($display['display_options']['path']) && $display['display_options']['path'] != 'taxonomy/term/%' ) {
return Url::fromRoute(implode('.', [
'view',
$view->id(),
$display['id'],
]));
}
$request = \Drupal::request();
$url = Url::createFromRequest(clone $request);
$url->setAbsolute();
return $url;
}
