I’m trying to use “#states”. When my checkbox is true, I want to make “required” another field. Drupal prints the “required” asterisk but not correctly.
Here it’s the code:
// Return origin. $form['search']['return']['return_ori'] = [ '#attributes' => [ 'class' => ['field-autocomplete', 'ret-ori-name'], 'data-type' => 'busstop', 'placeholder' => t('Write your origin', [], ['context' => 'Backend']), 'required' => TRUE, ], '#default_value' => !empty($_GET['return_ori']) ? $_GET['return_ori'] : '', '#prefix' => '<div class="row"><div class="col-md-5">', '#states' => [ 'required' => [ ':input[name="search_return"]' => [ 'checked' => TRUE, ], ], ], '#size' => 40, '#suffix' => '</div>', '#title' => t('Return origin'), '#type' => 'textfield', ]; // Return trip. $form['search']['search_return'] = [ '#default_value' => !empty($_GET['search_return']) ? $_GET['search_return'] : FALSE, '#prefix' => '<div class="row"><div class="col-md-5">', '#suffix' => '</div></div>', '#title' => t('Search return trip'), '#type' => 'checkbox', '#attributes' => [ 'class' => ['search-return-trip'], ], ];
The submit button has not specific method, so Drupal should handle it. When I press it, the form is sended ignoring my new required field.
Thanks all for help!!
