I’m trying to add a “cancel” button to my content type.

In hook_form_alter(), I’m using this code:

  if ($  form_state->getFormObject()->getOperation() == 'default') { // On node add, make it clear "cancel" deletes any input     // Do not show cancel button to people who have not completed their profile.     if ($  user->hasPermission('create MYTYPE content')) {       $  form['actions']['submit_cancel'] = array (         '#type' => 'submit',         '#weight' => 999,         '#value' => t('Delete all input and return to previous page'),         '#submit' => array('MYMODULE_userpageredirect_callback'),         );       $  form['actions']['submit_cancel']['#attributes']['class'][] = 'btn-danger';     }   } 

….

/**  * Cancel changes and return to previous page  * @param array $  form  * @param FormStateInterface $  form_state  */ function MYMODULE_userpageredirect_callback(array &$  form, FormStateInterface &$  form_state) {   $  route_name = 'user.page';   $  form_state->setRedirect($  route_name); } 

This creates a cancel button that returns the user to the user page when they click cancel.

Problem

If a field is marked required, and the user has not input any text in the field, the browser prompts the user to input a value into the field before the cancel button will work.
